Introduction
This thermostat can replace common residential thermostats. It is designed for use with most
central heating and air conditioning systems that use low voltage (24V or millivolt) system control.
Please see compatibility chart on the next page for more details.
Warning
We recommend consulting a licenced HVAC contractor to ensure the correct installation of the
thermostat. The only way to guarantee proper wiring is to have a qualified professional on site.

Replacing the Old Thermostat
Wiring
NOTE: WIRING COLORS ARE NOT ALWAYS STANDARDIZED, SO IT IS VERY IMPORTANT TO
LABEL ALL WIRES ACCORDING THE LETTER DESIGNATION ON YOUR OLD THERMOSTAT
(The wires are usually designated 'W', 'Y', 'G', 'RH', 'RC', 'W' ,'B', ‘O' or humidistat wires
Disconnect wires from old thermostat or sub-base
As you disconnect each wire, label it with the old terminal designation
Take care not to let the wires fall back into the wall or let the ends of the wires touch one another
If there is an extra wire that is not connected to your old thermostat, then you won't need to connect
it to the new thermostat

Humidifier Wiring
To wire a humidifier, the 2 wires connecting the original humidistat need to be
connected to the 2 terminals marked 'H1' and 'H2' on the thermostat.
The original humidistat should be removed or set to 'OFF' position.
Note: The 2 humidifier control terminals 'H1' and 'H2' are electrically isolated from the Heat/Cool
terminals.
Note: H1 and H2 terminals are non polarized and there is no function difference between H1 and H2.

Connecting the Wires to the Terminals
Connect the previously labeled wires to the corresponding
terminals, matching the designations. Use a screwdriver to
loosen the terminal, wrap the wires around the terminal then
tighten to securely fasten the wires. Make sure the wires do
not touch or short-circuit with other terminals.
Depending on your heating/cooling equipment, you may need to connect between 2 to 7 wires
If you have two ‘R’ wires, then connect each wire to its corresponding terminal and remove the
JUMPER between the RC and RH terminals
If you are unsure of the connections please consult a certified HVAC contractor for the correct
installation of your thermostat.

The back cover should be mounted vertically with the terminals on the top
Thread the existing wiring through the big center hole from the back and set the back cover
vertically on the wall
Select two appropriate mounting holes and mark the locations with a pencil (If necessary, use a
level to make sure the thermostat is positioned straight)
Remove the back cover from the wall and drill two 3/16 inch holes in the marked screw positions
Insert the wall anchors into the holes completely (If necessary, use a hammer to tap-in lightly)
Mount the back cover to the wall using the two screws (Make sure the metal terminals are on the top)
Attach the thermostat body to the back cover (that is already mounted on the wall)
by carefully aligning the two pieces and pressing firmly until they snap together

This thermostat is equipped with a remote sensor, which monitors the temperature in a remote location
and can control the thermostat by sending a radio signal.
Controlling the thermostat with the remote sensor / transmitter:
Note: If you wish to use the remote sensor make sure the RF option is set to RF1 (see optional settings)
The remote sensor is capable of doing three things:
lTransmitting the room temperature from a remote location to display on the thermostat LCD screen
lThe thermostat will heat o cool your home based on the temperature transmitted by the remote instead
of the temperature of the thermostat.
l Overriding the current temperature setting to raise or lower the temperature up to 3°C ( )
or 6 ° ( ).

SYMBOLS:
Viewing the temperature of the remote transmitter:
The local and remote temperatures display alternates every 8 seconds on the thermostat LCD screen. To view the
remote transmitter temperature, press AHEAD on the thermostat. The temperature will be shown on the bottom
pane and the Remote Temperature Display symbol (antenna) will appear indicating the temperature displayed is
from the remote transmitter. If the bottom pane is already showing remote temperature (the Remote Temperature
Display symbol already on), pressing AHEAD key will show the local temperature of the thermostat.
Controlling the thermostat based on the remote transmitter temperature (Heating or Cooling):
The thermostat can heat or cool your home based on the temperature transmitted by the remote, instead of the
thermostat's own temperature. To begin, place the remote sensor in the part of the house you wish to use for
temperature control. Press the ON/OFF button on the remote transmitter until the Remote Temperature Control
symbol displays. The thermostat will now control the heating and cooling based on the temperature as sensed by
the remote transmitter. (Note: If the local temperature on the thermostat and remote vary by more than 4 degrees,
or either remote transmitter or thermostat battery is low, the remote function will be cancelled.)
Remote Override:
raise or lower the set temperature by up to 3 °C or 6 ° . Press the UP or DOWN buttons on
the remote override value displayed as a plus or
minus value on the LCD screen of the remote. It will also appear on the thermostat LCD screen, alternating with

When the AA batteries are low and need to be replaced the low battery symbol will appear on the
LCD screen and a beep will sound every hour. However, it is recommended that the batteries be
replaced every year, even if the battery symbol does not appear.
To replace the batteries:
Select OFF to change the thermostat to OFF mode
Remove the thermostat from its mounting plate (back cover) carefully
Remove the old AA batteries and install new ones
Place the thermostat back into its original position
Note: If the batteries are low the backlight will not turn on and the remote control feature will not
work. After changing the batteries, complete the LEARN PROCEDURE again to connect the
thermostat and remote sensor / transmitter. (see the remote sensor/transmitter section)
The backlight helps you to clearly see the thermostat display at night. However, frequent backlight
use will reduce your battery life. To disable the backlight see the “Optional Settings” section.

Memory backup for the Programs and Thermostat Settings
In case of power outages, this thermostat has a memory backup powered by a lithium battery.
The lithium battery will typically last for several years. Memory storage includes all set programs
and thermostat settings. Do not remove the Lithium battery and the AA batteries at the same time,
otherwise all memory and settings will be lost.
SOFT RESET - If the thermostat has an abnormal display, press the RESET (R) button located at the
back of the thermostat. The programs and thermostat settings will remain stored in memory but the
clock will have to be set again.
HARD RESET - To clear the permanent memory (including all stored programs and settings) or to
change the temperature scale (°C or °F), a hard reset must be performed. Press and hold the
HOLD button, and at the same time press and release the RESET (R) key located on the back of the
thermostat. The LCD screen will blank out momentarily. When the display reappears, release the
HOLD key. The thermostat will be back to its default settings.

PROBLEM SOLUTION
Battery symbol ( ) is flashing.
LCD screen is blank.
Heat will not come on.
- Check if the batteries are installed correctly.
- Check if the batteries are fresh and of the correct type.
- Select RESET button on the back of the unit.
- This is an indication that the batteries are running low. Replace with fresh alkaline batteries.
Note: We recommend replacing the batteries at least once a year even if the battery symbol is
not flashing.
1) Check and ensure that the thermostat is set to the HEAT or AUTO mode.
2) Check and ensure that the set temperature is higher than the current (room) temperature.
3) You may have to wait up to 5 minutes before the heat will turn on. The thermostat has a built-in time
delay to prevent undesirable on/off sequences.
4) After a 5-minute wait, the heat should now be on. Whenever the heating system is running, the
symbol will be animated.

PROBLEM SOLUTION
Heat will not come on but the
symbol is animated.
Air conditioning will not come on.
Air conditioning will not come on
but the symbol is animated.
The thermostat turns the heating
or cooling systems on before my
programmed set times.
Heating system seems to cycle
too often.
1) Check if the furnace switch and/or pilot flame is turned on, as it may have been turned off.
2) Allow several minutes for the heating system to heat up and the fan to activate. Most heaters will heat
up the system for a short while before warm air can be ventilated by the fan. Also check that the
HE/HG setting is set correctly. (see optional settings)
3) If the heat still does not come on, check the wiring installation again.
1) Check and ensure that the thermostat is set to the COOL or AUTO mode.
2) Check and ensure that the set temperature is lower than the current (room) temperature.
3) You may have to wait up to 5 minutes before the air conditioning will turn on. The thermostat has a
built-in time delay to protect the air conditioner compressor from undesirable on/off sequences.
4) After a 5-minute wait, the air conditioning should now be on. Whenever the cooling system is
running, the symbol will be animated.
1) Check if the air conditioning system’s main switch is turned on, as it may have been turned off.
2) Wait several minutes for the air conditioning system to activate. If the air conditioning still does not
come on, check the wiring installation again.
This is normal if the Pre-comfort Recovery system is enabled. The Pre-comfort Recovery will activate
the heating/cooling in advance of the actual programmed set time so that the room will be at the
desired temperature at the start of the program time. See the “optional settings” section.
Check and ensure that you have selected a Cycle Rate that matches your particular heating system.
If you find it still cycling too often, you may wish to try a slower cycle rate or disable the cycling.
When disabled, the thermostat will operate at a fixed span of (plus or minus) ±0.5°C (±1.0°F).
For example, if the programmed temperature is set at 20°C (68°F), the thermostat will turn the heat
on if the current (room) temperature falls below 19.5°C (67°F) and turn the heat off when the current
(room) temperature reaches 20.5°C (69°F). See the “optional settings” section.

PROBLEM SOLUTION
Thermostat is set on AUTO mode,
but the thermostat does not seem
to automatically change-over from
HEAT to COOL or vice-versa.
While adjusting the program
temperature or program times
in the HEAT mode, you notice the
changes affect the settings in
the COOL mode; and/or
vice-versa
Cannot change the thermostat
scale from °C to °F or vice-versa.
The thermostat has a built-in safeguard time delay of 30 minutes to prevent undesirable change-over
sequences from HEAT to COOL or COOL to HEAT. For example, if the thermostat was just running the
cooling system, it will take at least 30 minutes before it changes to heating. You may override this
manually by pressing MODE to change the operation to HEAT or COOL only.
The heating and cooling program times are linked, so same program start times (chosen for either
heating or cooling) will automatically be applied to the other.
When you set the HEAT and COOL program temperatures fairly close to one another, the thermostat
automatically restricts the two temperature settings from getting within 3°C (6°F) of one another.
The COOL temperature setting will always be at least 3°C (6°F) higher than the HEAT temperature
setting. For example, if the initial COOL program temperature was set at 24°C (75°F) and you decide
to adjust the HEAT program temperature to 24°C (75°F), the thermostat will automatically push the
COOL program temperature up to 27°C (81°F) to prevent overlapping.
Selecting the temperature scales is a one-time start-up process. After the first battery installation, you
must HARD reset the thermostat and choose the desired display in °C or °F. Otherwise, you CANNOT
change the temperature scale (°C or °F) later on unless you perform another HARD reset which will
clear all the programs and thermostat settings.
To perform a HARD reset and select °C or °F, first press and hold the HOLD, while at the same
time press and release the RESET button on the back of the thermostat. The LCD screen will blank
out momentarily. To select °F, select see the “optional settings” section.

The thermostat is not receiving a
signal from the remote transmitter.
Re-do the “Lean Procedure” to ensure an RF signal is being transmitted from the remote sensor to
the thermostat. (See “Remote transmitter” section)
The clock symbol is flashing This indicates that the 3V (CR2025) lithium battery is low. This will not affect the normal operation
of the thermostat, but it should be replaced to ensure memory backup is maintained. Replace the
lithium battery with a screwdriver. (See diagrams for the location of the lithium battery)
