Installation

The following tools may be required for installation:

( ) Screwdriver

Masking Tape

(To wrap the exposed wires temporarily and to label the disconnected wires)

Wire Stripper/Cutter

(If necessary, to strip the wires)

Power drill with a 3/16” bit

( If necessary, to drill holes on the wall )

Level

(If necessary, to level the thermostat)

Batteries (included)

Choosing a location for the thermostat

Thermostat should be mounted:

Approximately 5’ (1.5 m) from floor.

Near or in a frequently used room, preferably on an inside partitioning wall.

On a section of wall without pipes or duct-work.

Thermostat should NOT be mounted:

Near a window, on an outside wall, or next to a door leading outside.

Exposed to direct light or heat from a lamp, sun, fireplace, or other

temperature-radiating objects which may cause false readings.

Near or in direct airflow from heat registers and air conditioners.

Near concealed pipes and chimneys.

In areas with poor air circulation, such as behind a door or in an alcove.

Replacing the Old Thermostat

Test the system to make sure that your heating and cooling systems are working properly before

(

installation If either does not work, contact a heating/air conditioning service person to fix the

)

problem before installation

TURN OFF POWER to system at the furnace, or at the fuse/circuit breaker panel

Carefully unpack your new thermostat and mounting plate; save package of screws,

instructions and receipt

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.

Humidistat should be OFF or disconnected

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.

Mounting the back cover of the 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

First attach to backplate to the wall, then press the faceplate into place

- 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 is not receiving a signal from the remote transmitter.

The clock symbol is flashing

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.

Re-do the “Lean Procedure” to ensure an RF signal is being transmitted from the remote sensor to the thermostat. (See “Remote transmitter” section)

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)
