Thermostat Quick Reference
Battery Installation
Battery installation is recommended even if the thermostat is
hardwired (C terminal connected). When the thermostat is hardwired
and batteries are installed, the thermostat will activate a compressor
delay of 5 minutes when it detects a power outage from the hardwired
power supply.
Important:
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 are recommended.

Caution:
Electrical Hazard
Failure to disconnect the power
before beginning to install this
product can cause electrical shock
or equipment damage.
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 the
terminal block screws.
3.
Place nonflammable insulation into
the wall opening to prevent drafts.
Wiring Tips
C Terminal
The C (common wire) terminal does
not have to be connected when the
thermostat is powered by batteries.
Wire Specifications
Use shielded or non-shielded 18-22
gauge thermostat wire.

To release battery cover press finger bevel
on the left side and lift the cover to access
batteries.
Simple operating instructions
are found on the back of the
battery door.
Warning:
All components of the control
system and the thermostat
installation must conform to
Class II circuits per the NEC Code.
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.
