    How to manually open honeywell V8043F1036
    I'm troubleshooting my heating system and I think a zone valve is stuck closed. Thermostat is calling for heat but the hot water pipes (hot water baseboard heat) are not heating up. I have four zones and the others are heating just fine. I replaced the thermostat so have narrowed it down to zone valves.

    Most zone valves will allow you to open them manually so open it up and see if it gets hot. Move the lever to open.

    Manual Lever
    The V8043 normally closed valves can be opened manually by moving the manual lever slowly and firmly to the MAN. OPEN position and pushing up to the stop. The stop permits the valve to be locked in the open position. The valve returns to automatic position when it is energized.

I manually opened one of my home's five Honeywell zone valves (V8043E-1012) by mistake. I meant to open a different valve. The one I opened had its thermostat set to its lowest temp setting, as it controls heat to a space I hardly ever heat. The next day the valve was still in the open position...
