I am trying to find a programmable thermostat control for our heating system which has two zones. The boiler is Worcester Highflow 550CDi.
I quite like the FR110 controller with load compensation. But...
Worcester says none of their controls are compatible with zones systems. I fail to understand why. Is this because they are low voltage and cannot drive the zone valves? Does anyone know?
Are there any other programmable thermostats with direct burner control load compensation? I can't find any...
Thanks for any help!
