Room Setpoint command is not working on my thermostat

Post by cakiroglu »

Hi,

I have got problem with my thermostat because it is not setting room temperature value sent by opentherm gateway.

My thermostat is Bosch TRZ200. But when I open the case I can read Honeywell CS0257A-LS
I coluldn't find much details about it on google.
This is a pic of it while it is without case.

Here is an example log output that showing the problem. I think. it is not recognising the code as it says.

If it is going to help I can provide more logs and info.

Do you have any advise on that kind of situation ?

Thanks.

This only shows that the gateway is not sending an override setpoint to the thermostat. Why not is unclear from the available data.

So yes, more logs would be necessary to determine what is going on. From a few minutes before you give the TT or TC command until 10 or 15 minutes after would be preferred. Please also indicate which firmware version you are using.
