1. A High Air Temperature alarm can occur if the inlet air temperature is warmer that
the PreHeater High Air Temperature alarm setting. Press the key combination Set
– Set – Air Temp to view the inlet temperature of Supply Air. This temperature
must be below the High Alarm Setting.
2. Press the key combination Set – Set – Pre Heater to view the pre heater
temperature setting. Confirm that the temperature is below the High Alarm Setting.
Determine if customer assigned values have been installed to replace factory

electrical enclosure, and observe the green LED located on the SSR-2. The LED
indicates the operating status of relay. When LED is ON the air heater element is
energized. Confirm that the LED is OFF when air temperature is at or above the
control set point. Replace the SSR-2 relay if the green LED remains ON. CFH-RS

3. Check the operation of Air Pre-heater solid state relay SSR-2. Open AC electrical
enclosure, and observe the green LED located on the SSR-2. The LED indicates
the operating status of relay. When LED is ON the Air Pre-heater element is
energized. When LED is OFF the air heater element is de-energized. Confirm that
the LED is OFF when the air Pre-heater temperature is at or above the control set
point.
If the air temperature is above the control set point and the relay SSR-2 is ON,
replace the relay. (CFH-RS part number 77780152).
