Programmable Thermostats.
If you have already wall thermostat and you want to upgrade to a programmable thermostat. You have some homework to do first.
What voltage is it running on? Thermostats come 2 ways, line voltage and low voltage. Line voltage is comes in 120 to 240 volts. Low voltage is 24 volts which is a smaller wire you can tell just by looking at it.
Not all thermostats can control every HVAC system. Is you have a water boiler for you baseboard don’t confuse this with an electric heater baseboard thermostat. Heat pumps run on different thermostats then standard Spit systems. It’s sounds confusing but if you know what type of system your trying to control someone can point you down the correct path.
Programmable unit can save you energy, but you have to leave the house for longs periods for it to payoff. If someone is home everyday than you seldom have the change to drop the temperature. You will only use it for sleeping at night.
The true purpose of a programmable thermostat is it never forgets. You can control you temperatures your self. But every time you forget to drop the temp during the day your wasting fuel. And don’t forget your always waking up and coming home to a cold room.
