zone valve problem on controller or relay?
I have a two honeywell zone valves connected to one relay and one pump. recently, I found the zone 1 for my basement works well but there is something wrong on zone 2 for the first floor. When I increase the temperature on zone 2, the zone valve is open and I can heard the sound for the movement of endswitch but the pump doesn't start. I searched online and tried to jump the TT of replay but the pump still doesn't start. However, when I remove the wire connected to the relay and then reconnect, the pump start running. However, after few days, same thing happens and I will do the same thing to start the pump. I called the electrician to come and check and he told me it is the problem of controller not the relay. But I am wondering if it is the problem of controller, then the pump should still keep quiet when disconnect and reconnect the wire between controller and relay. What I am thinking is that if there is any possible that the two connections on the relay for Zone 2 is not connected well. When I disconnect and reconnect, they may work for a while but stop after few days. Any suggestion/solution?
Because it will a big job to change the whole controller then I want to make sure it is really the problem of controller rather than the problem on the relay or connections. Thanks in advanced.
I am not sure if I have clearly presented the problem since this is the first time to have this question. If you need any information, I will add them according to your suggestions. Thanks.
