It is usually the case that a <b>permanently lower room temperature &lt;20\u00b0C<\/b> is desired in the bedrooms, corridors or fitness room than in the living rooms, lounges or swimming pool with &gt;21\u00b0C. <\/p>\n<p>A modern KNX heating actuator, which should actually be called a heating actuator with integrated heating controller, is very often selected as a component without knowing the details and functions in detail. Either because it is recommended to the electrician by a trusted wholesaler or simply because it comes from the same manufacturer as all the other components anyway. <\/p>\n<p><span style=\"font-size: 17px;\">There are basically three types of heating systems that can be found in buildings today:<\/span><\/p>\n<ol style=\"font-style: normal; font-size: 17px;\">\n<li style=\"font-size: 17px;\">as <b>underfloor heating<\/b>, almost classic as in most cases of new construction<\/li>\n<li style=\"font-size: 17px;\">as <b>wall-mounted radiators<\/b> or radiator heating where old radiator valves have been replaced<\/li>\n<li style=\"font-size: 17px;\">as <b>electric heating<\/b> or infrared heating\/window heating as is common in bungalows<\/li>\n<\/ol>\n<p style=\"font-style: normal; font-size: 17px;\">Each of the 3 variants must be controlled and regulated in a house using a KNX heating actuator. It does not matter how large the house is or whether a combination of the three different variants is required. <\/p>\n<p><span style=\"font-size: 17px;\">In the DIY sector, people often <b>buy according to the &#8220;cheapest price&#8221;<\/b>, which is why we are also looking at this topic here. Specifically, it&#8217;s about the   <\/span><span style=\"font-style: inherit;\">Best price per heating channel or actuator output<\/span><span style=\"font-size: 17px;\">. Und gerade in diesem Punkt gibt es sehr gro\u00dfe Unterschiede. <\/span><\/p>\n<p>The fact that the decision to buy the right KNX heating actuator is anything but trivial is shown by the frequent problems encountered by building owners who have already moved into their new house or villa. Want some examples? It is often too cold in the rooms of a newly built house or it only gets warmer or colder with a long time delay. Or the heating is on full blast, so that the residents have to open the windows in a cold sweat. This is shown by the inquiries we receive.    <\/p>\n<p>Or the <b>heating\/cooling switchover<\/b> does not work, even though it is supported by the heat pump. Ultimately, <b>everything depends on the KNX heating actuator<\/b> and can be traced back to its functions and settings, which are anything but trivial, even if it seems so at first glance.

PWM is an abbreviation for &#8220;pulse width modulation&#8221;. Here, a 0 to 100 percent control value (with a 1-byte group address) is specified and sent by a room temperature controller.  <\/p>\n<p>Continuous PWM control is always used for underfloor heating and wall\/ceiling heating in new buildings and for component activation\/concrete core activation. The background: Due to the large quantities of water in the concrete\/screed, such water heating systems are very inert. The main advantage of continuous PWM control<b> lies in the premature reduction of the heating output<\/b> when <b>the actual value quickly approaches the setpoint<\/b>. In this case, the heating circuit control valves are already closed gradually, even though the setpoint value has not yet been fully reached.   <\/p>\n<p>With this control system, <b>room temperatures can be maintained<\/b> and ensured very <b>precisely<\/b>. And how does it all work? The desired setpoint is set on the heating controller &#8211; for example a KNX push-button. The heating controller in the KNX push-button measures the current room temperature and uses this to calculate the control value to be sent. Unfortunately, some KNX push-buttons do not have an integrated heating controller -&gt; see our <span style=\"text-decoration: underline; color: #3366ff;\"><strong><a style=\"color: #3366ff; text-decoration: underline;\" href=\"https:\/\/www.smartest-home.com\/en\/best-knx-push-buttons\/\" target=\"_blank\" rel=\"noopener\">Top 30 comparison of the best KNX push-buttons<\/a><\/strong><\/span>.    <\/p>\n<p>The advantage over all other controls of a heating actuator: With continuous PWM control, rapid temperature changes are counteracted prematurely.<\/p>\n<p>The KNX heating actuator converts the continuous manipulated variable signal (group address with 1 byte 0 to 100 percent) from the heating controller into corresponding switching pulses within the set cycle time. This process is called pulse width modulation, whereby on\/off signals are modulated within a PWM cycle. <\/p>\n<p><u>Here is a setting that we made on all test candidates as an example:<\/u><\/p>\n<p>PWM cycle set = 8 minutes<br \/>Control value = 75%<br \/>Result: the heating actuator opens the control valve for 6 minutes and closes it for 2 minutes. With a set PWM cycle of 30 minutes, the control valve opens for 22.5 minutes and closes for 7.5 minutes. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1f048f3 elementor-widget elementor-widget-image\" data-id=\"1f048f3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"723\" src=\"https:\/\/www.smartest-home.com\/wp-content\/uploads\/2024\/06\/Heizungsregelung-Stellantrieb-KNX-Heizungsaktor.jpg\" class=\"attachment-large size-large wp-image-48170\" alt=\"Heizungsregelung Stellantrieb KNX Heizungsaktor\" srcset=\"https:\/\/www.smartest-home.com\/wp-content\/uploads\/2024\/06\/Heizungsregelung-Stellantrieb-KNX-Heizungsaktor.jpg 800w, https:\/\/www.smartest-home.com\/wp-content\/uploads\/2024\/06\/Heizungsregelung-Stellantrieb-KNX-Heizungsaktor-300x271.jpg 300w, https:\/\/www.smartest-home.com\/wp-content\/uploads\/2024\/06\/Heizungsregelung-Stellantrieb-KNX-Heizungsaktor-768x694.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">230 volt actuator for a heating control system in an old villa with radiators.

Like the other manufacturers in the test field, MDT is a German company with a relatively short KNX history compared to the competition, but an even more extensive product range.   <br \/>MDT is going full throttle, especially with KNX actuators and their features, including the heating actuators. With a narrow width of 72 mm (only 4 TEs), the manufacturer packs 8 outputs including status LEDs into its KNX heating actuator. A maximum of 4 actuators can be connected to each output: This makes <b>a total of 32 actuators<\/b>, which can be sufficient for many a detached house or even a new-build apartment. If you need more, simply use several heating actuators.   <\/p>\n<p>In contrast to the other test candidates, <b>MDT has dispensed with the option of manual operation<\/b> on the heating actuator itself, so that the 8 outputs can only be switched via the KNX bus using software. MDT has visibly saved on the simple housing and workmanship, but this does not affect the functions.   <\/p>\n<p>The MDT heating actuator supports the three familiar operating modes &#8211; continuous PI control, switching PI control (PWM) and switching 2-point control &#8211; just like the other competitors. One special feature: the settings in the <b>ETS software are clear<\/b> and much easier to understand than those of ABB and Hager, for example.   <\/p>\n<p>It goes without saying that the MDT AKH-0800.03 supports <b>both heating and cooling operation<\/b>. The latter is essential today in conjunction with a frequently used air-to-water heat pump, even in the lower house construction price segment, so that it is possible to switch to cooling mode in summer when temperatures are hot. Finally, the heating actuator must also support this in order to enable room temperature control via KNX button or touch panel. Or everything can be completely automatic without any external intervention, whereby a good deal of practical experience is required for parameterization\/programming.     <\/p>\n<p>We probably don&#8217;t need to mention the typical modes such as &#8220;Comfort&#8221;, &#8220;Night reduction&#8221;, &#8220;Standby&#8221; and &#8220;Frost\/heat protection&#8221; here, as these have been available for KNX heating actuators for over 15 years and are hardly relevant in practice.<\/p>\n<p>All in all, the MDT AKH-800.03 heating actuator takes first place with its good features, its outputs for 32 actuators, the simple housing (with processing flaws) and its very reasonable price of approx. 140 euros.

The top model is the Theben HM 12 T KNX <b>with a total of 12 outputs<\/b> for controlling actuators. With a width of 144 mm (8 TEs), the heating actuator takes up twice as much space in the control cabinet as the MDT AKH-0800.03 (with 8 outputs).  <\/p>\n<p>Theben allows the connection of <b>up to 36 actuators<\/b> via the 12 outputs and is therefore also suitable for a larger detached house with 3 to 4 floors and approx. 180 to 230 square meters of living space. As usual with Theben, the settings in the software are logical and almost self-explanatory. In the past, we have very often carried out our technical planning with heating actuators from Theben, as the support and updates have also suited us.  <\/p>\n<p>For those who prefer convenience, the Theben heating actuator is also available in a version for placement in the heating circuit distributor. This saves on the power cables and the KNX cable is routed to the heating circuit distributor instead.

With a width of 107 mm (6 TEs), it takes up little space in the control cabinet.   <br \/>Elsner provides each channel with 8 watts of power, so that theoretically a maximum of 8 actuators (each with 1 watt) can be connected to one output. Wow, no other test participant can do that! This means that <b>a total of 64 actuators<\/b> can be controlled <b>at the 8 outputs<\/b>. As with all other test candidates, all outputs on the Elsner heating actuator can be set as heating controllers or as &#8220;classic&#8221; heating actuators. Manual operation is available with LED status displays, which can be switched off in the software if required. Overall, the Elsner K8 heating actuator is not quite as well equipped as MDT and Theben, but it still commands the highest price in this comparison test. In terms of price per channel, it comes in second place behind the MDT.      <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0cf6333 elementor-widget__width-initial elementor-widget elementor-widget-progress\" data-id=\"0cf6333\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"progress.default\">\n\t\t\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t<p class=\"elementor-title\" id=\"elementor-progress-bar-0cf6333\">\n\t\t\t\tElsner KNX K8 heating actuator 8-fold rating\t\t\t<\/p>\n\t\t\n\t\t<div aria-labelledby=\"elementor-progress-bar-0cf6333\" class=\"elementor-progress-wrapper\" role=\"progressbar\" aria-valuemin=\"0\" aria-valuemax=\"100\" aria-valuenow=\"93\" aria-valuetext=\"93% (Processing quality  )\">\n\t\t\t<div class=\"elementor-progress-bar\" data-max=\"93\">\n\t\t\t\t<span class=\"elementor-progress-text\">Processing quality  <\/span>\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-progress-percentage\">93%<\/span>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6455e06 elementor-widget__width-initial elementor-widget elementor-widget-progress\" data-id=\"6455e06\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"progress.default\">\n\t\t\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\n\t\t<div class=\"elementor-progress-wrapper\" role=\"progressbar\" aria-valuemin=\"0\" aria-valuemax=\"100\" aria-valuenow=\"81\" aria-valuetext=\"81% (Features &amp;

comes to the best price\/performance ratio of all KNX heating actuators, the <strong>MDT AKH-0800.03 heating actuator<\/strong> with its 8 outputs is by far the best. Added to this is the fact that up to 32 actuators can be connected to the MDT heating actuator for heating control &#8211; with a width of just 72 mm in the electrical control cabinet. This is enough for many &#8220;normal&#8221; detached houses up to 160 square meters or larger apartments. We have listed it in the table above:   &nbsp;<\/p>\n<p>MDT comes to 4.38 euros per actuator output if all 32 possible actuators are used. The manufacturer has dispensed with &#8220;manual operation&#8221;, which is acceptable in view of the many good features. On closer inspection, there are compromises to be made in terms of workmanship and quality of detail, but these should hardly bother anyone as the MDT heating actuator disappears out of sight in the electrical cabinet.

KNX<\/strong> is the best choice for controlling up to 36 heating circuit valves. We have been particularly impressed by the good and very simple software parameterization for years, which can also be found in the top model HM 12T KNX. The manual operation via buttons on the actuator and the LED status indicators convey a very good impression of quality that no other test participant can offer. In terms of price\/performance ratio, Theben is more in the middle of the field.<\/p><p>The third-placed <b>Elsner KNX K8 heating actuator<\/b> is unrivaled in terms of switching capacity: according to the data sheet, 8 watts can be switched per output. With an actuator with an output of 1 watt (as we often use), this theoretically results in up to 8 heating circuit valves per output and 64 heating circuit valves in total on the heating actuator. We have not yet tested where the practical limit really lies.<\/p><p>The <b>Hager TXM646R 6-way heating actuator<\/b> plays a special role, because despite its 6 outputs, it has 12 integrated heating controllers (the &#8220;R&#8221; stands for integrated heating controller). The configuration in the ETS software allows a wide range of options and in terms of price, Hager is in second place &#8211; which was not to be expected &#8211; just behind MDT.<\/p><p>Despite its 12 outputs and the control of up to 36 heating circuit valves, the <b>ABB VAA S.12 Heating actuator <\/b> not so convincing. The configuration in the ETS software is really reminiscent of the early 2000s! The outdated terms and designations can also only be understood straight away by &#8220;KNX insiders&#8221; who are very deeply familiar with the subject. In terms of price, ABB ranks more in the mid-range, although this should not be a purchase criterion for this heating actuator. The ABB heating actuator ends up in the project business anyway, where completely different rules apply in the context of tenders.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-57560db elementor-widget elementor-widget-author-box\" data-id=\"57560db\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"author-box.default\">\n\t\t\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-author-box\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.smartest-home.com\/en\/story\/\" class=\"elementor-author-box__avatar\">\n\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.smartest-home.com\/wp-content\/uploads\/2024\/06\/Smartest-Home-Team.jpg\" alt=\"Picture of Frank V\u00f6lkel &amp;
