temperature sensed by the working sensor every 10 seconds. The control will operate from the temperature sensed by the working sensor.

E1 − If the Display Module and the Equipment Control Module cannot communicate via two−wire connection, an E1 will be displayed.

E2 − There is no E2 error message.

E3 − If AC/HP Control cannot properly read outdoor temperature, and it is needed for proper operation, display will indicate “−−” in the outdoor temperature location.

E4 − If AC/HP Control’s internal memory fails, E4 will be displayed. Replace AC/HP Control.

Table 3 can be used as a troubleshooting tool for determining which outputs will be active for a particular configuration and each operating mode.

When replacing a failed component such as an equipment control module or a display module, the installer should replace both parts as a matched set. It is very easy to accidentally mix an A/C or HP display with a PAC equipment control module. When this happens, some functions appear in the setup while others do not. This can be very confusing to troubleshoot. Verify that both parts have the same model and serial number when troubleshooting the thermostat.
