On a system that uses a Heat pump, the heat setting utilizes the pump, and electrical coil heating as a backup.
On the EM setting the heat pump won't run, only the axillary coils will provide heat.
These two settings are found when you have a heat pump. Using the "Heat" mode uses the heat pump capabilities alone. Using em heat, turns on conventional electric coils to create more heat (and run up your electric bill)
Since you don't give any other information, you should start by making sure that you have electric power. Failing that, you might try checking the settings on your thermostat. You will want to be sure you have it set to cool, not heat the house and that the temperature setting on the thermostat is below the ambient room temperature.
The 160 thermostat should open about 20 degrees sooner than a 180.
The answer depends on the thermostat setting as well as the kind of heating system that you have.
Setting the thermostat to "auto" is generally more energy efficient and comfortable in the home compared to setting it to "on." This is because the "auto" setting allows the system to cycle on and off as needed to maintain the desired temperature, while the "on" setting keeps the system running continuously.
When setting up a Nest thermostat, use the RH wire if you have a heating system, and use the RC wire if you have a cooling system.
Setting your thermostat to "auto" is generally more energy efficient and can help maintain a comfortable temperature in your home. This setting allows the system to run only when needed, reducing energy consumption.
In the instruction manual for the furnace, it will either give you the heat anticipator setting or instruct you how to do it. If its digital, well then follow the thermostat instructions
To test a thermostat using a multimeter, set the multimeter to the resistance or ohms setting. Disconnect the thermostat from the power source and remove it from the appliance. Place the multimeter probes on the thermostat terminals. A functioning thermostat should show a specific resistance reading. If the reading is significantly different or shows as infinite resistance, the thermostat may be faulty.
there kind of the same really you should no the answer
Switches are usually made of Thermo Setting Polymers. Bakelite is an example.
it may blow cold air due to the fact that the heat anticipator on your thermostat may be set to long. you can change useing your owners manual for your thermostat but you should have a service tech do it
