Best guess: it thought it was daylight savings time. You may need to adjust the clock on the thermostat.
The answer depends on the thermostat setting as well as the kind of heating system that you have.
195 degrees F
70
A thermostat in general, is an assembly that measures temperature (if it measures room temperature then we are talking about a room thermostat) and trips an electrical contact on and off comparing measured temperature to a temperature setpoint (the temperature setting we set on the thermostat by means of a rotating knob or a digital screen and buttons. In an hvac system, we install a thermostat inside the room in which we want to control temperature and we set the desired temperature. If current temperature is below setpoint, then the contact trips, and the heating system heats the room. When measured temperature reaches the desired setpoint, thermostat trips off and the heating system will stop giving energy to the room. By starting and stoping the heating system, we achieve to set room temperature within some limits.
60 degrees C
Depending on your temperature setting, usually the best is about 70 degrees, it's best to set the thermostat, and leave it at a constant setting. Resetting your thermostat to higher temperatures requires the furnace work harder, and will usually increase your utility bill.
Reducing the thermostat setting by a few degrees in the winter reduces the amount of fuel burned to heat your house. In most modern houses the change in temperature won't even be noticed.
A person can tell if their home heat pump thermostat is working by setting the temperature a few degrees above or below ambient to see if it kicks on. A thermometer can be used to verify the temperature.
Your 1996 Mercury Villager minivan with the 3.0 L - SOHC V6 engine is designed to use The Ford Motorcraft RT 1170 thermostat ( 190 degrees F / 88 degrees C )
Yes you can count on the settings being above freezing, 0 degrees C or 32 degrees F. On a standard thermostat that controls baseboard heaters the low setting is 10 degrees C or 50 F. and the high setting is 30 degrees C or 86 F.
either your thermostat is bad or the flame sensor on unit is no good. it also can be a limit switch. if it lights and stays on for awhile but doesnt reach temperature then its thermostat. if it lights for 10 seconds it is sensor or limit switch.
Boiler should be set at max temperature of 180 degrees for proper heating temperature. 120 degrees is temperature for domestic hot water, not heating temperature. Yes, to answer question, but not recommended.Improved answer. -If you are referring to the hot water heater that gives water to your hot faucets this is not generally known as a 'boiler' (a boiler is for hydronic heating) Your faucet supply can be turned down to any setting between 110 and 160. Normal setting is 130-135. with small children it should be 120. - on most heaters there is an adjustment knob on the gas regulator or the lower electric element . It's well marked and easy to adjust.
