    If the water source heat pumps are performing most of the heating, this modification wasn't necessary. If the heat pumps are tied to the ems, and only maintain a minimum building temp over night, you could have reworked the scheduling so that they run over night without it getting too cold. There's more than one way to skin a cat, sir. Think about all of your options before you take such drastic measures next time. I would never bypass a safety and leave a unit running; not even to run to a supply house for parts.

    I agree with Isaac, if anything would have happened due to that solenoid being tampered with you could lose everything you ever worked for.

    What's the size of the boiler? Make and model. Old boilers used to have single blocking valve and now are required to have 2. Some applications will have a gas vent solenoid between the blocking valves. A well known brewery that we service had a fire side explosion. Even though they have boiler operators and dual blocking Valves an explosions still occur. Every shift change they perform a blocking valve tightness check. Even with checking this and 2 people that signed off on it they had an explosion rip an 1800 HP water right down the front middle face of the boiler. 2 people went to the hospital and came back to work a week later. Im sure some one wouldn't charge $2,000.00 to diagnose the valve. To repair it, it could cost that and then some depending on the solenoid.
