Boiler was overfilled. Drain approx 12-15 gallons to get water level to design. Checked over wiring, One big issue has been thermostat location it is in a corner about 10’ up on first floor where there is a breeze from entrance way. The temperature there is 7° cooler than the temperature in any of the apartments themselves. We installed Honeywell S1200 Elite pro thermostat with equipment interface module and a room sensor. Placed the room sensor on a wall in a second floor apartment and configured new thermostat to use this sensor as the temperature input. Set thermostat target 70° Monitored boiler operations. Set auto water feeder delay period to 10 min. Tightened packing nuts on 3 problem radiator valves. They were very lose. There are a couple air vents that need to be replaced. We will provide estimate. System will run alot less often now by virtue of having temperature being read from an actual apartment.
