Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
I have a Honeywell motorised valve in my CH/hot water system. I dont think it is working as it does not move and there is no resistance in the lever. The hot water still heats up when the CH is on and the Hot water is not being asked for, There are five wires to it but I dont know which wires do what. Is there an easy way I can test it to see if it is working and check if the wiring to it is correct. Thanks Dave
Hi two things that go wrong inside the valve gets clogged up and blocks up in side, the valve in side and get worn sorry 3 things the motor on the top burns out , if you remove the top cover you will see a small motor with 2 orange wires on it you can remove the motor with 1 screw and see if its turning
