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.
