I am trying to use following equipment for zone control:
* ATC928G3026 (evotouch) - central unit
* HR92 valve
* T87RF2025 thermostat
The HR92 is placed in the way that makes temperature measurement completely unreliable so I would like to use T87RF in some other place of the same room.
I played with following evohome settings to enable external temperature sensor:
* Heating type: Radiator valve (HR92 paired)
* Temperature sensor: Remote sensor (T87RF paired)
I could achieve one of the results, depending on the pairing order I guess:
1.
* Temperature measurement from T87RF, shown properly in evotouch screen and used for schedule
* T87RF could make manual overwrite of the temperature setting (overriding schedule)
* HR92 does not work
(no heat requests, no valve opening)2.
* Temperature measurement from HR92, also shown in evotouch screen and used for scheduling
* HR92 works OK - opens and requests heat as expected
* T87RF can be only used to manually overwrite set temperature but it's setting is referring to HR92 measured temperature
None of these is what I want
My target scenario is obvously:
* Temperature measurement from T87RF, shown properly in evotouch screen and used for schedule
* T87RF could make manual overwrite of the temperature setting (overriding schedule)
* HR92 requesting the heat and opening accordingly to T87RF measured temperatures and schedule
First of all, is my target sceanrio possible or there are some limitations which I am not aware of ?
Does pairing or configuration order of these devices matter ?
Is there some impact of another option "RF Device Binding (Devices Bound)" available in the zone control on my scenario ?
I would appreciate some hints.
Best,
Sebastian
