min to install, so next time when you have someone telling you this is the holy grail of the thermostats, talks or it does this or does that, take my word for it, he wants to rip you off, all digital thermostats work the same way , and most of them are programmable so don’t fall for that ..Now before we go any further let’s first understand what the thermostat actually does. The thermostat is nothing but a switch- yup you heard that right, it is exactly like your light switch. As a matter of fact, you can replace a thermostat with a light switch and the heat pump or the air conditioner won’t know the difference. only difference is that you turn the light switch manually but the thermostat will turn on or off based on a set temperature you can adjust.So the next time you are too hot and you want to turn your thermostat on don’t lower the temperature setting thinking you are making your air conditioner work harder. work any harder, it will just make the

air conditioner work longer to meet your low setting temperature,it is not a gas throttle what is the different between an air conditioner thermostat and a heat pump with the air conditioner: have a regular air conditioner you must also have a source of heating (mostSo when you need cooling your thermostat has to turn on the air conditioner (the compressor, the indoor blower and the outdoor fan), and when you need heating the thermostat has to turn on the furnace and the indoor blower. Thermostat uses 4 wires and one optional This thermostat is very easy to install and replace, and yet most contactors charge between $150 to $200 to do this. The thermostat only costs $25-$35 and takes less than five minutes to install.Remember, if you want to do this yourself.· Turn the air conditioner breaker off when you attempt to replace the thermostat.· Not everyone follows the same color code so always look at the old thermostat wiring. If the blue wire is connected to the Y terminal then connect the Blue wire to the Y terminal in the new thermostat.

If you have a heat pump you don’t have a furnace since the heat pump provides cooling and heating. So when cooling is required your thermostat has to turn on the air conditioner (the compressor, the indoor blower, the outdoor fan and put the reversing valve in the cooling mode). When heating is required the thermostat has to turn on the compressor, the indoor blower, the outdoor fan and put the reversing valve in the heating mode. It also has to turn on the Auxiliary Heater if needed and Emergency Heat if needed.The reversing valve is either turned on or off. 99% of time the reversing valve is on when the system is in the cooling mode and it is off when the system is in heating mode.Some old heat pumps are reversed, meaning that when the reversing valve is active it is heating and when it is off it is cooling. Most thermostats have both options: - either O or B- don’t connect you want to do this yourself, Turn the heat pump breaker off when you attempt to replace the
