thermostat

How do I wire 4 taco zone valves to 4 2 wire room thermostats and the boiler transformer??

Hi We got a Camray 5 Oil Boiler with a timer control panel, is it possible to fit a room thermostat instead or have timer and room thermostat? How would it control both turning the boiler on and turn on the heating pump? Can you get wireless models? Thanks

I just replaced the 30 amp breaker, the upper and lower heating elements, and thermostats. I have continuity all the way through the circuit, but the voltage stop going from the upper thermostat to the lower thermostat.
