Good day to you all I’m hoping someone can help me here.
My girlfriend had a new boiler installed a while back now and they never fitted a thermostat but all the radiators have thermostatic valves on them. I have installed Nest heating and followed a guide from on here and apart from a couple of the wires being an odd colour I followed the instructions and I thought all was working ok the hot water came on fine when called for but it turns out the CH was not coming on.
I have rechecked my wiring and I hear the click from the nest controls but the 3 way diverter valve does not move and the pump does not run.
It is a green star Ri erp +
It was controlled with a Drayton control panel on the outside of the airing cupboard with the hot water tank inside the airing cupboard along with the 3 way diverter valve and pump
The wiring I feel is a complete mess.
I’m wondering if the 3 way diverter valve has become faulty because if I put CH and HW on it heats the bathroom and toilet and the downstairs radiators but not upstairs.
