No Heat

1.) System Switch not set to Heat

2.) Loose connection to thermostat or system

3.) Heating System requires service or thermostat requires

replacement

Verify thermostat and system wires are securely 

attached.

Diagnostic: Set System Switch to Heat and raise 

the setpoint above room temperature. Within five 

minutes the thermostat should make a soft click 

sound and “Heat On” should appear on display. 

This sound indicates the thermostat is operating 

properly. If the thermostat does not click, try the 

reset operation listed below. If the thermostat does 

not click after being reset, contact your heating 

and cooling service person or place of purchase 

for a replacement. If the thermostat clicks, contact 

the furnace manufacturer or a service person to 

verify the heating system is operating correctly.

No Cool

1.) System Switch not set to Cool

2.) Loose connection to thermostat or system

3.) Cooling System requires service or thermostat requires 

replacement

Verify thermostat and system wires are securely 

attached.

Diagnostic: Set System Switch to Cool and lower 

setpoint below room temperature. Same 

procedures as diagnostic for “No Heat” condition 

except set the thermostat to Cool and lower the 

setpoint below the room temperature. There may 

be up to a 5 minute delay before the thermostat 

clicks in Cooling if the compressor lock-out option 

is selected in the installer menu. (see INSTALLER 

MENU, item 50)
