Installation Guide

Introduction

This thermostat can replace common residential thermostats and it is designed for use with
most central heating and air conditioning systems that use low voltage control. Please see
the compatibility chart on the next page for more details.

3 “AA” size batteries required (included)
Built-in protection timing for the air conditioner compressor

Warning

It is recommended to consult a wiring professional to ensure the safe installation of your thermostat.
The only way to guarantee wiring safety is to have a qualified professional on site. Since each
residence may be wired differently, UPM’s customer service line cannot offer any wiring advice.
UPM assumes no responsibility for customer errors in installation or wiring or any resulting damages.

* NOT COMPATIBLE WITH ANY HIGH VOLTAGE 120/240 VOLT CIRCUIT.

System Testing

It is very important that you fully test your heating, cooling and humidity equipment, both
before and after installing your new thermostat. The first test will determine if the equipment is
operational at the beginning of the process; the second test will ensure that the wiring and
installation were completed correctly.

It may be tempting to only test the heating equipment if you install the thermostat in the winter, or to
only test the air conditioning and humidifier if you install it in the summer. However it is highly
recommended to test all equipment at the time of installation.

SYSTEM TESTS: (BEFORE AND AFTER INSTALLATION)

- Make sure power is on for all heating and cooling appliances.

- Ensure the thermostat is switched to HEAT mode.

- Raise the temperature setting to see if furnace will activate. (May take up to 10 minutes)

- Ensure the thermostat is switched to COOL mode.

- Reduce the temperature setting to see if the air conditioner will activate.

(Note: Do not activate air conditioning if the temperature is below 10°C (50°F)
as this may damage the outdoor compressor.)

- Ensure the thermostat is switched to HEAT mode.

- Increase you humidity setting to see if the humidifier will activate.

- For heating systems with more than three wires, put the fan in the ON position.
(The fan should come on immediately.)

Fan Operation Jumper HE/HG

Depending on your home’s heating system you may need to
change the jumper setting for the fan operation. The jumper
is located on the back of the thermostat.

HG - Use this setting for gas and oil-fire powered furnaces.
This setting allows the fan operation to be controlled
by the heating system; not the thermostat. This is the
correct setting for most systems.

HE - Use this setting for electric powered furnaces. With this
setting the thermostat will turn on the fan immediately with the
heating system.

The jumper is pre-installed in the HG position as a factory default.
So there is no need to change the jumper if this setting is correct.

To change the jumper setting to the HE position, pull out the small black
rectangular block and align it to the new position and push it in fully.

Choosing location for new 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

Note: Do not operate the cooling system when outside temperature is below 10°C (50°F) to avoid
damaging the compressor.

9

Replacing 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. Remove cover from old thermostat. If it does not snap off when pulled firmly from the bottom,
check for a screw used to secure the cover. Loosen screws holding thermostat to the wall and lift
away the 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, use masking tape
to 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.

10

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.
After aligning the wires to the correct terminal push
excess wires back into the wall hole.

Depending on your heating/cooling equipment, you
may need to connect 2 to 7 wires to the thermostat.
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 electrician for the safe installation of your
thermostat.

Mounting the thermostat back cover

The back cover should be mounted vertically with the
terminals to the left.
Thread the existing wiring through the big center hole
from the back and set the back cover vertically on the
wall.
Select the mounting holes and mark the locations with
a pencil. If necessary, use a level to make sure the
thermostat is leveled.
Remove the back cover from the wall and drill two
3/16” 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 with the screws.
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.

or FAN) has accumulated to 500 hours of use. It is an indication that the furnace filter should be changed
at this time. To reset the FILTER CHANGE counter, press and hold the USAGE button for 3 seconds. (The
filter change icon will appear for a second.) This brings the filter usage counter back to zero.

29

Battery Changing

When the battery symbol is visible on the LCD screen, it indicates that the batteries are running low and
need to be replaced. However, it is recommended that the batteries be replaced every year, even if the
battery symbol does not appear. Always use new high alkaline quality batteries. Do not place previously
used, mixed brand or rechargeable batteries into your thermostat.

To replace batteries:

Slide the HEAT/OFF/COOL switch to the OFF position.
Remove the thermostat from its mounting plate (back cover) carefully.
Remove the old batteries and install new ones very quickly.
Return the thermostat to its original position.

NOTE: If new the batteries are inserted within 20 seconds of removing the old ones, the existing time will not
be cleared. Otherwise, the display may show an incorrect time and the clock will have to be set again.

Backlight

The backlight helps you to clearly see the thermostat display at night. However, frequent
adjustments with the backlight enabled will reduce your battery life. To disable backlighting see
the “Option Section”. (The backlight function will work only in the dark, because the unit detects
light with photo-sensitive sensors.)

SIGNAL INTERFERENCE:

There are 15 HOUSE CODE choices to reduce the chance
of signal interference from other electronic devices. If any signal
interruption occurs changing the HOUSE CODE (1-15) may
correct the problem.

Mount the remote transmitter upright avoiding metallic objects
and frames, such as window sills. Verify that there are no obstacles
like a transmission tower or a steep hill that would cause interference
or block the signal between the remote transmitter and receiver.

TROUBLESHOOTING GUIDE

PROBLEM SOLUTION

LCD screen is blank.

Battery symbol ( ) is flashing.

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 to have the batteries replaced 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 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 heating should now be on. Whenever the heating system is running, the
symbol will flash.

5) Double check the wiring. You may verify the correct wiring letter designation by seeing which wire is
attached to which letter code inside your furnace. (see installation: wiring section)

38

PROBLEM SOLUTION

Heat will not come on but the
symbol is flashing.

Air conditioning will not come on.

Air conditioning will not come on
but the symbol is flashing.

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, if not change the position. (see Fan Operation Jumper HE/HG section)

3) If the heat still does not come on, double check the wiring installation.

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 flash.

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. You may disable this feature in the
“option section”.

Check and ensure that you have selected a Cycle Rate that matches your particular heating system.
The default is set at Cr-3 for gas or oil forced air systems. 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).

39

PROBLEM SOLUTION

Cannot change the thermostat
scale from °C to °F or vice-versa.

Selecting the temperature scale is a one-time start-up process. After the first battery installation, or after
you press the reset button, you may choose °F within 3 seconds. (°C is the default so it will display
automatically after the RESET.) Otherwise, you CANNOT change the temperature scale to °F
later on, unless you perform another reset which will clear all the programs and thermostat settings.
The reset button is located on the back of the thermostat. Press RESET and °C will appear, then
press the UP or DOWN buttons to select °F. The °F setting is now permanent.
