Override max CH temperature
Posted: Thu Feb 14, 2019 5:13 pm
Hi,
I have recently got started with OTGW with Honeywell Evohome and an Ideal Vogue c32 gen2 boiler. The reason for investigating OTGW was to try to set the maximum flow temperature of the boiler.
By default when using opentherm with the Ideal boiler the central heating flow temperature is set to 80 celsius, I was hoping to be able to change that.
When I use the configure>heater menu to set max CH setpoint it seems to be immediately overwritten.
Is anyone able to suggest a way that I can limit my flow temperature?
Many Thanks
Here is a section of my log file which I think covers it (I tried to set the max temperature to 58):
