I’ve got an interesting problem.The sytem is a TARM Excell 2000 with an ARGO ARM-6 switching relay to control my 5 heating zones. It has an isolated switch relay (X-X) that opens a valve and turns on a circulating pump.
One day I noticed that all my zones were calling for heat but the pipes were cold. I could tell the valve was not open so as I started to trace the wires I jiggled the wires on the X-X connections and the valve opened. This happened a couple of times so I cut the last inch or so of wire off and reconnected them. This seemed to solve the problem but last night it happened again.
This time however after jiggling the wires and having the valve open I was watching the panel and the whole thing goes dead. Figuring it was the 120 volt feed I pushed on those wires and lo and behold everything comes back on. It did this a couple of times and then finally stayed energized.
Of course this happens during the worst cold snap we’ve seen in 10 years (2 degrees last night).
Any idea what the h**l is going on? I’ve tightened the connections, disconnected and reconnected the wires and blown out the dust.
The system is in its 6th season and I’ve never had this problem before.
