Hi,
Until now I used the OTGW with a Honeywell touch modulation in combination with a Siemens PLC. The PLC controlled the boiler completely.
Now I have moved to another house and am forced to use a wireless (RF) thermostat.
The thermostat in the new house is a Honeywell wireless. I can connect this directly to the boiler via RF.
But the boiler does not transmit thermostat data to the OTGW. So then I bought a Honeywell opentherm RF module to connect to the OTGW.
Now I can read thermostat data. But unfortunately it always sends the room temp as 20C.
So now I am searching for a RF thermostat which can send the actual room temperature and setpoint in a decent accuracy (0.1C) and frequency.
Every 2 or 3 minutes new data would be ok.
According to the thermostat OTGW matrix the Honeywell Wireless modulation should work.
Can someone tell me how the Honeywell Wireless modulation responds?
Other options are also welcome.
