STEP 1
If your heat is not working.
Are your heating wires identified, labeled, and connected correctly?
RH, R, and W
There is no standard color code. Some of the wires may have the same color as the letter (like R or RH is often red and W is often white) but do not count on the color. The labels on the wires should be the same letters as where they were connected on the old thermostat.
If you cannot determine the letters from the old thermostat, go to the furnace unit and try to identify the wires that go to the thermostat location as the terminals at the furnace are usually labeled. Be sure the power to the furnace is shut off.
If you cannot accurately identify the wires letters, do not guess, call your local HVAC service dealer.
STEP 2
Is your furnace operational?
To check this, with the thermostat off the wall, short the RH and the W terminals on the thermostats back plate. Wait a few minutes. You should hear your furnace go on. If it does not, consult an HVAC service dealer.
STEP 3
If your cooler is not working.
Are your cooling wires identified, labeled, and connected correctly?
RC or R and Y
There is no standard color code. Some of the wires may have the same color as the letter like R or RC is often red and Y is often yellow). The labels on the wires should be the same letters as where they were connected on the old thermostat.
If you cannot determine the letters from the old thermostat go to the HVAC site and try to identify the wires that go to the thermostat location as they are usually labeled. Be sure the power to your HVAC system is shut off.
If you cannot accurately identify the wires letters, do not guess, call your local HVAC service dealer.
STEP 4
Is your Air Conditioner operational?
To check this, with the thermostat off the wall, short the Y and the RC terminals on the thermostats back plate. Your compressor and outside fan should immediately come on. If it does not, consult an HVAC professional.
Note: The duty cycle for the cooling compressor will require several minutes for ‘recovery’, that means you cannot do this test multiple times in quick succession.
Allow 5 minutes between tests for compressor recovery.
STEP 5
If your fan switch is not working.
Do you have a fan wire and is it connected?
The Fan wire should be labeled G.
Is your G-wire identified, labeled, and connected correctly?
Does that wire connect to the fan unit?
There is no color code. Some of the wires may have the same color as the letter (like G is often green) but do not count on the color. The label on the fan wire should be the same letter as where it was connected on the old thermostat.
If you cannot determine the fan letter from the old thermostat, go to the HVAC site and try to identify the wires that goes to the thermostat as they are usually labeled. Be sure the power to your HVAC system is shut off.
If you cannot accurately identify the wires letters, do not guess, call your local HVAC service dealer.
STEP 6
Is your Fan operational?
To check this, with the thermostat off the wall, short the G and the RC terminals on the thermostats back plate. You should hear your fan go on.
If it does not, consult an HVAC service dealer.
STEP 7
Does the FAN switch work, but the fan does not come on in heat?
You probably have an electric furnace that needs the thermostat to control the fan. Change the GAS/ ELECT jumper on the back of the thermostat to ELECT.
STEP 8
If nothing is working.
Check to power to the HVAC system by checking your breakers. If there is an ON/OFF switch on your furnace, be sure it is on.
Check the batteries in your thermostat. Are your batteries Alkaline batteries? Are they fresh with a high state of charge?
Check the power to the thermostat by using an AC voltmeter.
For heating, with the thermostat off the wall, measure the AC voltage between the RH and the W. It should read about 24VAC (+/- 3V).
For cooling, with the thermostat off the wall, measure the AC voltage between the RC and the Y. It should read about 24VAC (+/- 3V).
STEP 9
Heating is working but not cooling or cooling is working and not heating.
Take the thermostat off the wall. Put it back on making sure the top plastic latches are in place as you pull the thermostat down. This is important to make sure all the pins on the thermostat are making good contact on the back plate sockets.
STEP 10
The buttons seem to be erratic or do not work at all.
Push the RESET button with a paper clip.
STEP 11
Operation seems unpredicatable. The buttons seem to be erratic or do not work at all.
Are your batteries Alkaline batteries? Are they fresh with a high state of charge?
STEP 12
I have wires marked W2, E, or X. Where do I connect these wires.
If your old thermostat has a W2 or E, or X wire, and/or two mercury bulbs, and/or an emergency heat (emer) position on switch.
You probably have a 2 stage heat pump system.
You need a Ritetemp thermostat model 8010, 8050C, 8082C or 8085C these are specifically compatible with 2 stage heat pumps and other 2 stage heating systems. If you are not sure please contact technical support.
Done
Your system should now be operational.
If your system is still not working correctly, please check all the steps once again.
After you have rechecked your steps for installation, and trouble shot your system, you can contact via email.
