No Heat

 

1.

Pilot light not lit.

 

Re-light pilot.

 

 

2.

System button not pressed to display Heat.

 

Set SYSTEM button until HEAT is displayed and

 

 

 

 

 

raise temperature above room temperature.

 

 

3.

Loose connection to thermostat or system.

 

Verify thermostat and system wires are securely

Diagonistic: Set SYSTEM button until HEAT is

 

 

 

 

 

displayed and raise setpoint above room

 

 

 

 

 

temperature. Within a few seconds the thermostat

 

 

 

 

 

should make a soft click sound. This sound

 

 

 

 

 

usually indicates the thermostat is operating

 

 

 

 

 

properly. If the thermostat does not click, try the

 

 

 

 

 

reset operation listed on the previous page. If the

 

 

 

 

 

thermostat does not click after being reset contact

 

 

 

 

 

your heating and cooling service person or place

 

 

 

 

 

of purchase for replacement. If the thermostat

 

 

 

 

 

clicks, contact the furnace manufacturer or a service

 

 

 

 

 

person to verify the heating is operation correctly.

No Cool

 

1.

System button not pressed to display Cool.

 

Set SYSTEM button until COOL is displayed and

 

 

 

 

 

raise temperature below room temperature.

 

 

2. Loose connection to thermostat or system.

the condition persists the manufacturer of your

 

 

 

 

 

system or service person can instruct you on how

 

 

 

 

 

to test the Heat/Cool system for correct operation. If

 

 

 

 

 

the system operates correctly, replace the thermostat.

Furnace Cycles Too Fast or Too Slow

 

1.

The location of the thermostat and/or the size

 

Digital thermostats normally provide precise

influencing the cycle rate.

 

some older mechanical models. A faster cycle

 

 

 

 

 

rate means the unit turns on on off more frequently

 

 

 

 

 

but runs for a shorter time so there is no increase

 

 

 

 

 

in energy use. If you would like to increase the

 

 

 

 

 

cycle time, refer to page 6 under Installer Table for

 

 

 

 

 

settings. If an acceptable cycle rate is not acheived

 

 

 

 

 

by the adjustment in the Installer Table then you

 

 

 

 

 

may want to contact a local heating and air

 

 

 

 

 

conditioning service person for further suggestions.

Cooling Cycles Too Fast or Too Slow
