Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater
Temp is set to 50 degrees....it is eighty in here....help!!
Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

Make sure the switches on the back of the thermostat is set for hot water heat. If you have more then 1 zone you may a stuck zone valve or a short in the wiring somewhere keeping the boiler on.
