Error codes (thermostat & remote control)

If E1 or E appears, check error code number (right side of screen):

23 EIM does not have dual fuel capability. Replace EIM if you have fossil fuel

backup heat or change Installer Setup Function 4 to ELECTRIC if you have electric backup heat (see pages 8-10).

29 Attempting to connect incompatible wireless devices.

30 Invalid zone number. Zone number must be set to zero (see page 6).

33 Check Return Air Sensor wiring. If removing the sensor permanently, press and hold the CONNECT button on the EIM for 10 seconds (until flashing orange) to clear

this error code. See page 15, then pages 5-8 to reconnect wireless devices.

34 Low signal strength. Move wireless device to a different location and try again.

38 Make sure Connected light on EIM is flashing and you are 2+ feet away from EIM.

53 Thermostat is not receiving Outdoor Temperature and Outdoor Humidity:

1. Thermostat may be configured for dual fuel, compressor lockout or auxiliary

lockout with no outdoor sensor. Follow Wireless Setup procedure to connect outdoor sensor to the EIM (see pages 5 and 7).

2. If E53 continues, outdoor sensor may not be communicating. Install 2 fresh AA Lithium batteries in the outdoor sensor.
