Arrived on site to diagnose insufficient heating. After our initial inspection, we found that the heating setting on the boiler was set to only 122 degrees. Set it to 160 and burner would now come on when needed. Zones are heating up properly. Karen would like to replace her three old Honeywell thermostats. We will provide a quote for replacement. Currently zone 2 and 3 are jumped together at the zone control board as zone 3 thermostat (upstairs) is not working properly.
