Installation Tips
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.

For vertical mount put one screw on
the top and one screw on the bottom.
To connect the base module to the master thermostat, refer to the
directions on page 13 of this manual.
Note:
Wire the base module’s subbase the same way you would wire a
hardwired thermostat subase.

The base module must be hardwired (C and R terminals connected to
24V power.)
Note:
Align the 4 tabs on the subbase with corresponding slots on
the back of the thermostat/base module, then push gently until
it snaps in place.
Note:
To ensure a solid fit between the thermostat/base module
and the subbase:
1.
Mount subbase to a flat wall
2.
Use screws provided
3.
Drywall anchors should be flush with the wall
4.
Wires should be pushed into the wall

Battery installation is optional if there are no remotes
connected to the Master Thermostat (C terminal con-
nected).
If you connect an outdoor remote and/or
indoor remote sensors it is required the
thermostat be hardwired.

High quality alkaline batteries are
recommended. Rechargeable batteries or low quality
batteries do not guarantee a 1-year life span.
Insert 2 AA Alkaline
batteries (included). High
quality alkaline batteries
