12/6/2019 . Completed install 4 new zone valves. Traced out each individual circuits and transformer feeding the valves. Found that one valve anytime time there was a call for heat on any zone had sent heat directly to the 2nd floor loop. Changed it to 1valve feeding the second floor, and the labeled each loop. Anytime boiler is heated circulator pump will always energize when the boiler limit hits 140 degrees.

Found thermostat reading fine when I arrived. This thermostat can not be replaced with just a Honeywell t-6. It is a Bryant communicating thermostat. With module at indoor air handler. Outdoor sensor is also designed for this set up. Checked over system and from talking to tennet. It was ethier an issue with the system itself or the computer sitting on the desk in front of the thermostat heat rising up the temperature. Told tony to call us if they have an issue again. Checked refrigerant pressures they were good.
