generate heat demand without thermostat
I'm trying to put a user-friendly face on my boiler. As-is I have jumped SH1 to create the demand, I'm using the boiler's ODR/WWSD & constant circulation, and I have three thermostats & actuators connected to a Caleffi ZVR106 to limit the heat in each bedroom. I'm not using any other functions of the ZVR.
I'm looking to add some kind of control on the wall in the living space to make ODR adjustment easier AND generate the demand. The Tekmar 256 looks like it will put a pretty face on the ODR but I still need some kind of switch to generate the demand, something simple & clean looking.
Any suggestions on generating the demand or combining the ODR & demand?
