Status Codes

Table 7 shows the status codes flashed by the amber status light. Most system problems can be diagnosed by reading the status code as flashed by the amber status light on the control board.

EXAMPLE:

3 short flashes followed by 2 long flashes indicates a 32 code. Table 7 shows this to be low pressure switch open.

The codes are flashed by a series of short and long flashes of the status light. The short flashes indicate the first digit in the status code, followed by long flashes indicating the second digit of the error code.

The short flash is 0.25 seconds ON and the long flash is 1.0 second ON. Time between flashes is 0.25 seconds. Time between short flash and first long flash is 1.0 second. Time between code repeating is 2.5 seconds with LED OFF.

Codes are easily read from user interface (UI)

Emergency Mode Connections with a Conventional Dual Fuel Thermostat

In an emergency, it is possible to replace the UI with a conventional heat pump thermostat (must be dual fuel capable if using a furnace), see Fig. 19 for wiring. However, this emergency mode operation is limited to a single, maximum compressor speed in heating and a single maximum cooling speed.
