Operation

Refer to the ignition control module diagnostics section for the LED diagnostic definitions.

When the fan selection switch is set to the "Auto" position, the RTRM energizes the supply fan relay (F) coil approximately 30 second after initiating the heating cycle to start the supply fan motor (IDM).

The automatic reset high limit (TCO1), located in the bottom right corner of the burner compartment, protects against abnormally high leaving air temperatures.

The automatic reset fan fail limit (TCO2), located in the upper middle section of the supply fan board, protects against abnormally high heat buildup which could occur because of extended cycling of the high limit (TCO1) or if the supply fan motor (IDM) fails to operate. Should TCO2 open, the RTRM will energize the supply fan relay (F) in an attempt to start the fan motor. The RTRM signals that a heat failure has occurred by flashing the "Heat" LED on the zone sensor.

There is a Green LED located in the Ignition Control Module. The table below lists the diagnostics and the status of the LED during the various operating states.

Final installation checklist

Is the condenser fan and indoor blower operating correctly, i.e.: correct rotation and without undue noise?

Are the compressors operating correctly and has the system charge been checked?

Has the gas module been installed as per the procedure in this manual?

Have the voltage and running currents been checked to determine if they are with in limits?

Have the air discharge grilles been adjusted to balance the system?

Has the ductwork been checked for air leaks and any condensation?

Has the heating air temperature rise been checked?

Has the indoor airflow been checked and adjusted if necessary?

Has the unit been checked for tubing and sheet metal rattles orany unusual noises?

Are all covers and panels in placeand properly fastened?

To keep the unit operating safely and efficiently, the manufacturer recommends that a qualified service technician check the entire system at least once each year, or more frequently if conditions warrant.
