Mount Thermostat
Align the 4 tabs on the subbase with
corresponding slots on the back of the
thermostat, then push gently until the
thermostat snaps in place.
Installation Tips
Note: To ensure a solid t between the
thermostat and the subbase:
1. Mount subbase to a at wall
2. Use screws provided
3. Drywall anchors should be ush with the wall
4. Wires should be pushed into the wall
Installation Tips
The thermostat should be installed approximately 4 to 5 feet above the
oor. Select an area with average temperature and good air circulation.
• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind the thermostat
• In areas that do not require conditioning
• Where there are dead spots or drafts (in corners or behind doors)
• Where there might be concealed chimneys or pipes
Wall Locations
Pick an installation location that is easy for the user to access. The temperature
of the location should be representative of the building.
Installation Tip
Do not install thermostat in these locations:

Caution:
Electrical Hazard
All components of the control
system and the thermostat
installation must conform to
Class II circuits per the NEC Code.
Warning:
Do not overtighten terminal
block screws, as this can
damage the terminal block.
A damaged terminal block
can keep the thermostat
from tting on the subbase
correctly or cause system
operation issues.
Installation Tip
Max Torque = 6in-lbs.
Wiring
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 Gterminal.
Loosen the terminal block screws.
Insert wires then retighten the

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. Simple operating instructions
are found on the back of the
battery door.
To release battery cover press nger bevel
on the left side and lift the cover to access
batteries.

Thermostat Quick Reference
The low battery icon is displayed when the AA battery power is low. Whenever the
thermostat detects low battery voltage from the AA batteries, the low battery icon will
begin ashing on the screen for 21 days (if the batteries are not changed). If the batteries
are not changed 22 days after the thermostat detects low battery voltage, the thermostat
screen will only show the ashing battery icon until buttons are pressed. If the batteries
are not changed 43 days after the thermostat detects low battery voltage, the thermostat
screen will only show the ashing battery icon until buttons are pressed and the set points
will oset to 85°F/29°C in cooling and 55°F/13°C in heating. At this stage, set point changes
can be made temporarily but, the set points will change back to defaulted values after a
4-hour period. The thermostat will continue to perform this low battery ashing,
temperature oset condition until the internal voltage threshold is reached. When the
thermostat internal voltage threshold is reached, all relays will be opened and the
thermostat will become inoperable until new batteries are installed.

The swing setting often called
“cycle rate”,“dierential”or
“anticipation”is adjustable. A
smaller swing setting will cause
more frequent cycles and a larger

Cooling
Swing
The cooling swing setting
is adjustable from 0.2˚ to

degrees for heating and the thermostat is set at 70˚F, the rst stage will turn
on at approximately 69.5˚F. The second stage will turn on at 69˚F. The second
stage will turn o at 69.5˚F and the rst will turn o at 70.5˚F.
