Error Codes —
If control cannot properly read space tem-
perature, display will indicate “--” and all outputs (except fan,
if on) will turn off. In the case where the installer has selected
to average the local sensor and the remote sensor, the control
display will alternate between “--” for the failed sensor and the
temperature sensed by the working sensor every 10 seconds.
The control will operate from the temperature sensed by the
working sensor.
CODE E1 — If the display module and the equipment control
module cannot communicate via two-wire connection, E1 will
be displayed.
CODE E2 — Not used.
CODE E3 — If control cannot properly read outdoor tempera-
ture, and it is needed for proper operation, the display will indi-
cate “--” in the outdoor temperature location.
CODE E4 — If internal memory fails, E4 will be displayed.
Replace the thermostat.
CODE E5 — If the thermostat cannot properly read humidity,
E5 will be displayed. Replace the thermostat. If both Humidifi-
cation and Dehumidification have been set to OF, the humidity
value will be shown as “–” when viewed from the humidity
menu, but no E5 will be shown in the display.
