Significant improvement over the old heating actuator

Compared to the old heating actuator of the new heating thermostat turns out significantly more voluminous. But he makes for the same price a very high-quality impression; not least because of the union nut of metal. In addition, the heating thermostat can now work completely autonomously without wall thermostat. Alternatively, it can, however, also be combined with the new wall thermostat HM TC-IT-WM-W-EU. Here then in groups of up to eight heating thermostat. In addition, can be divided into the groups the previous Fensterdrehgriff- and door contacts integrate. The group then works also very easy on the CCU2 (from CCU1 is the group function is not yet supported) and automatically creates the corresponding direct links.

Positive on new heating thermostat is also very easy to read and background lit display. The new boost function for rapid heating makes sense. Unlike the old heating actuator so far I could also not 0 or 4 - find bug -%. Say the heating thermostat the heating valve closes reliably complete if required.

Another note about the firmware update. I've gotten five of the current radio-actuators in use. Four were originally with version 1.0, a provided with version 1.1. The update to firmware version 1.2 ran in all five heating thermostat without any problems with the CCU2. A precondition is that they are connected by radio directly with the CCU2 and eg no LAN adapter is interposed for radio range magnification. In this case, the standard connection must only be set again and the heating thermostat be placed within radio range of CCU2 in the WebUI CCU2.

But a few things have me nevertheless somewhat negatively noticeable:

1. In the display, only the set temperature, but not the valve position and / or the actual temperature is displayed.
2. Also in the favorites of the WebUI CCU2 the valve position is no longer displayed.
3. I would appreciate it if you enter the parental PIN the boost function may be activated by, for example, a three seconds, press the Boost button to lock the thermostat.
4. There is no way to manually operate the valve of the radiator when the batteries of the thermostat are empty.

Nevertheless, the new heating thermostat is a thoroughly successful development.
