[QUOTE="Mr. Mach-ete, post: 9835579, member: 16424"] Jumping the thermostat out at the water storage tank should create an electrical pathway for the current to flow and energize the 24vac solenoid coil that allows 180 boiler water to circulate via a pump from the boiler through the water storage tank and back to the boiler, it's just a loop. Take a voltage meter and read the voltage across the thermostat. If it read 24 vac then the thermostat is open. If it reads 0.00 then you either have a closed thermostat or no voltage at the thermostat. If you read 0.00 VAC, check to see if you have control voltage at the thermostat by reading the applied voltage from one or both terminals to ground. If you read 0.00 from either leg to ground you have no control voltage at all. If you read 24VAC from either terminal to ground you have control voltage but the thermostat is not closing. Get back to me, let me know what voltage readings you have. If your patient we might walk through this, if not, call your local HAVC contractor. [/QUOTE]
