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.

Features

Temporary and Permanent Hold Feature
When cool or heat is turned on, the thermostat will display HOLD
and RUN SCHED on the left of your screen when you press the
or button.
Temporary Hold: At this time if you do nothing, the temperature will
remain at this setpoint temporarily until next time period.
Permanent Hold: If you press the HOLD key on the left of your
screen, you will see HOLD appear below the setpoint temperature in
the display. The thermostat will now permanently stay at this
setpoint and can be adjusted using the
To Return to Running Schedule: Press the RUN SCHED button on
the left of your screen to exit either temporary or permanent hold.
Filter Change Reminder
If your installing contractor has configured the thermostat to remind
you when the air filter needs to be 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 from the top left side of the
thermostat for 3 seconds.

Wiring

Wiring
1.
If you are replacing a thermostat,
make note of the terminal
connections on the thermostat
that is being replaced. In some
cases the wiring connections will
not be color coded. For example,
the green wire may not be
connected to the G terminal.
2.
Loosen the terminal block
screws. Insert wires then
retighten terminal block screws.
3.
Place nonflammable insulation
into wall opening to prevent
drafts.

Terminal Designations

C
Common wire from secondary side of
cooling system transformer
O
Heat pump changeover valve
energized in cooling
B
Heat pump changeover valve
energized in heating
(fan) is on.
W
Heat relay

Wiring Tips

RH & RC Terminals
For single transformer systems, leave the
jumper wire in place between RH and RC.
Remove jumper wire for two transformer
systems.
Heat Pump Systems
If wiring to a heat pump, use a small
piece of wire (not supplied) to connect
terminals W and Y.
Installation Tip: Do not overtighten terminal block screws, as this
can damage the terminal block. A damaged terminal block can
keep the thermostat from fitting on the subbase correctly or cause
system operation issues. Max Torque = 6in-lbs.
