Hello all,
My circulator pump is not getting 120 v I have 24 v at T. When I manually push the relay on the transformer I get voltage and the circulator and boiler started any ideas?

Shut the power off to the relay and disconnect both thermostat wires to T & T.
Turn the power back on and check for 120volts at #! .
If you have power at 1&2 use a jumper to jump between T & T.
If the relay pulls in and starts the boiler and circulator when jumped it is probably good. If the relay does not pull in it is bad.
You can get a new one at Supply House.com1 -
I thought about it last night after I starting pulling and testing wires I had work done in the house I bet they carpenters clipped my T stat wire from that zone. Thank you,0
