TROUblESHOOTING
• Check circuit breaker and reset if necessary.
• Make sure power switch at heating & cooling system is on.
• Make sure furnace door is closed securely.

Humidity Accuracy
+/-5% R.H. 20% to 60% R.H.
Electrical
Operating voltage 24vAC (18 to 30vAC)
verify the appropriate setting of dip switch 6. If the dip switch is set to use the on board sensor, but a remote sensor
is attached to T1&T2 then the temperature will read too high.
THE 8800 THERMOSTAT DISplAyS A VERy HIGH TEMpERATURE
• verify that the 8800 does not have an outdoor temperature sensor already attached and enabled.
• verify that the support module is set to address 1.

8081
This dip switch determines if sensor 2, which is the remote sensor on T3&T4, is a controlling (on) or monitoring (off)
temperature.
If the switch is set to off, sensor 2 will monitor the temperature. All monitoring values will cycle through the
message center on the thermostat.
If the switch is set to on, the 8800 thermostat will use sensor 2 as its controlling value which will also be displayed
at the 8800 thermostat. If multiple sensors are set to control, the values will be averaged and the average value will
be used to control the 8800 thermostat. The average value will be displayed as the controlling temperature on the
8800 thermostat.
8082
This dip switch determines if sensor 2, which is the on board humidity sensor, is a controlling (on) or monitoring (off)
humidity value.
If the switch is set to off, sensor 2 will monitor the humidity level. All monitoring values will cycle through the
message center on the thermostat.
If the switch is set to on, the 8800 thermostat will be set to humidistat mode and will use sensor 2 as its controlling
value which will be also be displayed at the 8800 thermostat. If multiple sensors are set to control, the values will
be averaged and the average value will be used to control the 8800 thermostat. The average value will be displayed
as the controlling humidity on the 8800 thermostat.
Note: If the 8800 thermostat has both humidity and temperature sensors set to control, the temperature
sensors will be used for control and the 8800 thermostat will display a CONFlICTING CONTROl SENSORS
message in the message center.
