Thermostat Quick Reference

Battery Door Information

Important:

The low battery indicator is displayed when the AA battery power is low. If the user fails to replace the battery within 21 days, the screen will only show the low battery indicator but maintain all functionality. If the user fails to replace the batteries after an additional 21 days (days 22-42 since first “low battery” display) the setpoints will change to 55˚F (Heating) and 85˚F (Cooling). If the user adjusts the setpoint away from either of these, it will hold for 4 hours then return to either 55˚F or 85˚F. After day 63 the batteries must be replaced immediately to avoid freezing or overheating because the thermostat will shut the unit off until the batteries are changed.

Caution:

When the battery icon low appears replace your AA batteries immediately. Failure to do so may result in your heating & cooling system becoming inoperable. Freezing or overheating can occur.
Filter Change Reminder
If your HVAC contractor has configured the thermostat to remind you when the air filter needs changed, you will see FILT in the display when your air filter needs to be changed.
Resetting The Filter Change Reminder: When FILT reminder is displayed, you should change your air filter and reset the reminder by holding down the second button down from the top left of the thermostat for 3 seconds.

Remote Information

When the R250S is used as an outdoor sensor and a dual fuel balance point is enabled, an outdoor temperature above balance point will cause the thermostat to only allow Y terminal(s) to energize. An outdoor temperature below balance point will cause the thermostat to only allow the W2 to energize.
The temperature shown is the average of all remotes, when using R251S indoor sensors.
When using the R250S as a floor sensor, High Limit may cause system to be off even when temperature isn’t yet satisfied. This is to avoid heating beyond setpoint.
