Fan Timer is Not Working
Step 1
Check to see if the LED display on the timer is lit up. If the display is dark, check that the main power supply is 120 volts of alternating current at 60 hertz. Contact an electrician to upgrade the power supply if it is less than 120 volts of alternating current at 60 hertz.
Step 2
Check the wiring diagram for the location of the fuse and line 1 that goes to the power supply. Find the fuse and line 1 on the unit. Locate standard terminal 1 on the wiring diagram and on the unit. Visually trace the voltage connection from line 1 to make sure it connects to the standard terminal 1 on the heater.
Step 3
Check the wiring diagram and then the unit for the location of line 2 and the neutral standard terminal 3 on the heater. Visually trace the voltage connection from line 2 to make sure it connects to the neutral standard terminal 3 on the heater.
Step 4
Call an electrician if the line 1 and 2 connections are not set up correctly.
Thermostat Does Not Work
Step 1
If the power supply is at the correct voltage and is hooked up correctly, determine the correct wiring from the thermostat to the cooling contactor by looking at the electronic fan timer wiring diagram.
Step 2
Trace the line voltage connections from the thermostat connector W to the cooler contactor connector W. Trace the line voltage connections from the thermostat connector Y to the cooler contactor connector Y. Trace the line voltage connections from the thermostat connector G to the cooler contactor connector G. Trace the line voltage connections from the thermostat connector R to the cooler contactor connector R.
Step 3
Call an electrician if the line voltage connections from the thermostat to the cooling contactor are not wired correctly.
Heat Delay Off is Not Correct
Step 1
Locate the DIP switches to set the heat delay off for the heater. Decide how long of a delay you desire before the heat goes off.
Step 2
Push the switches with your finger so that the switches both show a white box on top and a black box on the bottom if you desire a heat delay off of 60 seconds.
Step 3
Set the left switch with the black box on the bottom and the right switch with the black box on the top for a heat delay off of 120 seconds.
Step 4
Set the left switch with the black box on the bottom and the right switch with the black box also on the bottom if you desire a heat delay off of 140 seconds.
Step 5
Set the left switch with the black box on the top and the right switch with the black box on the bottom for a heat delay off of 180 seconds.
