Location
For accurate temperature detection, thermostats should be mounted
on an inside wall (46 cm or 18” from any outside wall) in a frequently
occupied area with freely circulating air. It should be approximately
1.5 m (5’) above floor. Avoid direct sunlight, radiant heat from appli-

ances, air conditioner grills, stairwells, water pipes, warm air stacks,
and sources of electrical interference such as arcing relay contacts.
Installation
1. Lift thermostat cover and insert flat blade screwdriver or coin,
approx. 3 mm (1/8”) into the slot located in bottom centre of case.
Twist ¼ turn to pop the thermostat loose from its backplate.
2. Swing thermostat from bottom (hinge at top), raise from backplate, and remove from hinge tabs. Place the backplate’s rectangular opening over control panel wires protruding from the wall.
Use backplate as a template to mark location of two mounting
holes.
3. Use supplied anchors and screws for mounting. Drill two 5 mm
(3/16”) mounting holes. Tap nylon anchors flush to wall and fasten backplate with screws.
4. Connect control panel wires to thermostat as shown in wiring
diagram. Push any slack wire back into wall. Dress remaining
wires to make them flush with backplate. Seal or stuff access
hole to prevent drafts through wall from affecting thermostat’s
performance.
5. Install optional setback, indoor/outdoor remote sensors, if used.
6. Replace thermostat to backplate by inserting its top into backplate’s hinge tabs, swinging downward and snapping back into
place.

OPERATING INSTRUCTIONS
The thermostat normally displays room temperature, mode of operation (i.e. Day or Night), and whether Cooling or Heating is currently
on. The six buttons on the front of the unit allow complete control of
the thermostat. The user may specify different Heating and Cooling
setpoints, and change them easily by pushing a button. Temperature
can be displayed in either C or F. The thermostat also allows the
user to select either continuous fan operation, or fan operation only
during operation of the heating/cooling device(s).

Modes
Select the desired mode of operation by toggling through them with
the MODE button:
❄ —controls Cooling system only (the word COOL is displayed for
5 seconds).
—controls Heating system only (the word HEAT is displayed for 5
seconds).
❄ —controls both the Heat and Cool systems (the word AUTO is
displayed for 5 seconds).
❄ (flashing)—indicates Cool ON.
(flashing)—indicates Heat ON.
OFF—disables thermostat so it will not operate.
Cooling: ❄
Select the temperature you want the thermostat to maintain
while in the Cool mode by pressing and holding the
or
buttons. The control setpoint temperature is displayed for 5
seconds.
Heating:
Select the temperature you want the thermostat to maintain
while in the Heat mode by pressing and holding the
or
buttons. The control setpoint temperature is displayed for 5
seconds.
Fan:
The Fan will come on automatically when the system is operating, but there is no indication of this on the display. To
select continuous Fan operation, press the FAN button and
the display will show . This is recommended for electronic
air cleaners and continuous ventilation requirements.
OFF:
When the word “OFF” is displayed, the thermostat will not
operate.
CAUTION: Avoid using the OFF mode during extremely cold
weather to prevent damage to equipment from freezing.
❄
Auto:
Selecting this mode of operation will control both Heating
and Cooling devices. The thermostat will automatically
switch from one to the other as determined by the selected
setpoints in heating and cooling.
NOTE: The thermostat will not allow less than 1 C (2 F) difference
between the heating and cooling setpoints.
Outdoor (ODT) Button
When the outdoor temperature sensor option is connected to your
thermostat, you can display the current outdoor temperature by
pressing the button. If this option is not connected, the thermostat
will display _ _
with no numbers.
Day/Night Button
When the thermostat is initially installed, the display will show the
symbol for your Day temperature. By pressing the Day/Night
button you may select the Night temperature where the display will
show the
symbol. This button can be used to toggle between
Day and Night modes. Within each mode the temperature can be
modified. The thermostat will remember any new settings.
Celsius/Fahrenheit
Simultaneously press and to toggle between Celsius ( C) and
Fahrenheit ( F) temperature display.
Remote Sensor (Option—RS1, RS2, RS+V)
The thermostat is designed to accept the Electronic Remote Sensor
(indoor or outdoor) so that temperatures remote from the thermostat
can be monitored. Indoor sensors increase the flexibility of where
the thermostat itself can be located. Indoor/outdoor sensors are
available separately.
Temperature Accuracy
Full accuracy is only achieved after the thermostat has been
installed and powered for at least one hour.
Power Failures
No battery is required to maintain the temperature setpoints in the
case of a power loss, regardless of duration.
