Question about Honeywell Programmable Thermostat Heater
I have recently had the above units fitted but the thermostat does not switch the heating on or off. After following the Drayton instructions i have found that the SRC unit does not fire the boiler when the stat calls for heat.The programmer works fine but i also require the use of the stat when the programmer is not in use.
Can you help?

HW valve was stuck in the open posiion and the micro-switch was not working so thats why boiler and pump were not starting. Bled system to below the level of the valve to be changed, and replaced valve with a drayton ( easy quick change of valve head if needed no screws )

yep the wires will hook up to the same designations, just write down what color was connected where. You will need to set the thermostat up for your particular situation...gas, electric, heat pump, ect. The installation maunel is very clear on this aspect so you should not have a problem.

R comonY cool W heat G fan C other side of 24 unless you are battery operated. On the back of the Tstat tou should have switch that says gas or electric this controls how the fan operates. If not go into programing and program 1 stage heat one stage cool.Let me know I will walk you thru this.
