EvoHome open therm
Posted: Sun May 18, 2014 10:48 pm
Hi,
Since a week I have the evohome system (color display) partly installed.
I have a display, an internet gateway and open therm module setup at this moment. Other parts are not connected yet.
At the evotouch, a single zone is installed in which the evotouch measures temperature.
Also the open therm module is linked. The signal strength when testing is 5 blinks, so that should be no problem.
Unfortunately, the heating does not start when temperature is set to 30 degrees Celsius for that zone.
When pressing the button on the open therm module, heating starts/stops (according to indicator on heater), so the heater is connected to the module correctly. But pressing the button is manual control, so not for normal use. After disconnecting the module, the evotouch unit indicates communication loss with the module, so communication really seems ok.
Should the evotouch indicate when heat is requested? Since I do not see any indicators for it.
Trying to resolve the issue, the evotouch display was completely reset and linked again to the open term module which was also fully reset. Unfortunately still no luck.
The module is connected to the heater (agpo econpact 27c) on pins 3 and 4.
Configuration is done by the wizard as well as by hand.
Does anyone have a clue what is wrong with this very basic setup?
I do not want to connect extra components until this works. I have read info about similar problems but this seemed to be the previous version of the device.
If more information is needed, don't hesitate to ask.
Thanks in advance for thinking along
