Valve control ?

I am trying to figure out my system. New to me house, 40 years old. Not sure how old boiler is. One zone (my bedroom) is particularly HOT. Does the valve control have anything to do with this?

Or are there anyother suggestions on what to do?
We have turned off the thermostat and it stays 70-74 degrees. Can't sleep!!

I have a honeywell #V8043F1036 valve control

 

The zone valve should actuate when the thermostat senses the room is too cold. Have Mr. RDH watch the zone valve while you move the thermostat from a high to a low setting and see if the valve is opening/closing as it should be. The valve could be stuck open, and allowing the heated water to self gravity feed through the pipes. Hot water rises.

 

Should this be set at auto or manual??

Thank You.

 

Automatic. Manual will allow the water to gravity feed.

From the Honeywell website:

Operation
Automatic Operation
On a call for heat by the zone thermostat, the valve opens and its auxiliary switch contacts make, closing the circuit to the system circulator. In a multizone system with all the valve auxiliary switches wired in parallel, any zone calling for heat can operate the circulator. When the call for heat ends, the
valve closes by integral spring return. The auxiliary switch contacts break the circulator circuit.

Manual Operation
The motorized valve can be opened manually by lifting the manual opening lever over the stop and pushing slowly and firmly to the MAN. OPEN position. The stop permits the valve to be locked in the open position. The valve returns to automatic position when the valve is energized.
