Battery Door Information

Thermostat Quick Reference

Insert 2 AA

Alkaline batteries

(included). High

quality alkaline

batteries are

recommended.

Located ont he back of the thermostat.

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 rst “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 o until the batteries are changed.

Important:

If your HVAC contractor has congured the thermostat to remind you when

the air lter needs changed, you will see FILT in the display when your air

lter needs to be changed.

Resetting The Filter Change Reminder: When FILT reminder is displayed,

you should change your air lter and reset the reminder by holding down

the second button down from the top left of the thermostat for 3 seconds.

Filter Change Reminder

•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 oor sensor, High Limit may cause system to be

o even when temperature isn’t yet satised. This is to avoid heating

beyond setpoint.

Remote Information

When the battery icon appears replace your AA batteries

immediately. Failure to do so may result in your heating & cooling

system becoming inoperable. Freezing or overheating can occur.
