Replaced the thermostat for the upstairs with a Pro One thermostat, non- programmable. Checked the operation. System is operating properly

Checked system, all three zones were calling for heat. The second floor is cold, tried purging the 2nd floor, there was no water coming out. Purged the other 2 zones with no issues. The 2nd fl zone is frozen due to the piping is in an overhang on the house. The pipes need to thaw out. The outdoor temp will be going back into the 40’s starting tomorrow. After the pipe thaws out, recommend adding glycol to the system, to help avoid this happening. The 2nd fl piping froze last year,January 31,2022 and glycol was also recommended at that time.

Through our diagonal we found that the circulator for the house was always on when the burner was on disconnected circulator to stop trying to push water through zone heads. Heat was operational for domestic water. need a return to reconnect circulator at another time and figure out which zone head is shorted out because it is causing the contactor to pull in on the aqua stat. Next time we’re hear we need to figure out what zone head is bad and reconnect the circulator to the aqua stat. I already took all the tstat off the wall.
