Increasing energy efficiency and reducing costs can be achieved by using the dual fuel
switch. Your heat pump can generally provide heat and comfort without assistance to an
outside temperature of just a few degrees below freezing. This temperature is called the
heat pump balance point. When the outside temperature is above the balance point, the heat
pump alone is sufficient for heating.
Once the outdoor temperature drops to the balance point the heat pump must be assisted by your
alternate energy source. When the outdoor temperature drops below the systems normal crossover
temperature (-12°C or -15°C), your heat pump will stop operating and the alternate energy
source will take over.

>>Operating Tips
• HUMIDIFICATION FAN should be set to ON when running steam or mist humidifiers.
• HUMIDIFICATION FAN should be set to OFF when running drum humidifiers or any other humid-
ifier that requires the furnace to run in order to make humidity.
• DE-HUMIDIFICATION FAN (DH) should be set to on when running separate de-humidification
equipment.
• DE-HUMIDIFICATION FAN (DH) may be set to off when using the air conditioning as a means of
de-humidification. It may advantageous in some environments to turn the fan on independent-
ly when there is a call for DH in order to distribute the humidity level more evenly.
• DH REVERSE function can be configured to meet the requirements of many variable speed fans,
consult the manual of your variable speed fan and determine if an “open” or “closed” contact
results in slowing fan operation.
>>De-humidification options for increasing comfort and efficiency
• HRV/ERV units can be controlled by simply connecting the DH terminal on the thermostat to the
terminal DH of the HRV/ERV. Most HRV/ERV units will control properly with the DH REVERSE fea-
ture turned off (contact normally open).
• OPTION 1: In Advanced Settings choose DHControlComp, set to ON then lower the temperature
to a minimum safe set point, finally set the desired de-humidity level, de- humidify will control
the compressor (unless minimum temperature set point is reached) whichever comes first.
• OPTION 2: Connect terminal DH to Y1 and set thermostat to de-humidify mode then regardless
of temperature the de-humidification setting will have priority. Caution: This method will run the
compressor until the de-humidification level is reached and may cause overcooling.
• OPTION 3: Connect the DH terminal to a variable speed fan control, (set DH REVERSE to control
the fan so that low speed is activated to de-humidify). This method provides maximum comfort
while maintaining the temperature in cooling mode.

thermostat can also function as a virtual non-programmable thermostat after it has been
switched to a “SIMPLE MODE”.
>>To enable “SIMPLE MODE”, press the reset button (take off the thermostat faceplate and press
the reset button located in the bottom right-hand corner). The message “Touch for simple ther-
mostat” will appear. Touch the screen immediately, and your LUXPRO
®
thermostat becomes a
simplified non-programmable thermostat.
>>“SIMPLE MODE” has the following temperature control modes:
>>“SIMPLE MODE” has the following fan operation modes:
Please note that when entering "Simple Mode" all configurations and settings are stored
permenantly.
>>To revert back to the Programmable LUXPRO
®
thermostat, simply press the reset button and
touch the screen when the message “Touch for Programmable Thermostat” appears.
? Touch screen buttons do not function properly. Remove cover, press the reset button located
in the bottom left corner then accurately touch 3 target centers on the screen when prompted.
? Air Conditioning does not turn on even when room temperature is higher then the temper-
ature set point set point. DHCONTROLCOMP is turned ON and dehumidify set point has been
reached. This will cause air conditioning to turn off. Lower Setpoint - Page 17, 21; Dh CON-
TROLCOMP - Page 39.
? Air conditioning turns on in HEAT mode and heating turns on in COOL mode. Reverse the
OB valve (see “Advanced Settings” Page 36).
? PARTIAL LOCK and FULL LOCK do not function. You must not touch the screen for 1 minute
for LUXPRO
®
thermostat to automatically lock.
? Thermostat appears normal until the screen becomes blank when the compressor or
heating system turns on. You need to connect the “C” wire. 4 wire system will not function
unless the heat and compressor contactors can supply enough current to power the thermo-
stat with only 4 wires, if you cannot hook up the “C” wire another possible solution is to connect
one 250 ohm 10 watt resistor in the HVAC room, for cooling problems between C and W or in the
case of heating problem between C and Y1.
? I forgot my PIN and cannot unlock the thermostat. Remove the cover plate, press the reset
button located in the bottom right corner, as soon as the message “touch to reset password”
appears touch the screen, your PIN will be erased and the thermostat will unlock.

IMPORTANT NOTICE

PSPU732T
>>WHEN USING THIS THERMOSTAT WITH A GAS FURNACE A COMMON WIRE (C) MUST BE
CONNECTED.
When working without a common wire:
>>A confirm in HEAT MODE the cooling does not switch on or B confirm in COOL MODE the heat do-
es not switch on.
>>If test A or B fail or the thermostat shuts down in either HEAT or COOL MODE then it is necessary
to connect a common wire, (C), alternatively it may be possible to solve this issue by simply
connecting the 250 ohm 10 watt resistor between C and W (in the case of a cooling problem -
see B) or between C and Y1 (in the case of a heating problem - see A) at the HVAC equipment.
>>When working without a common wire, A confirm that when there is a call for heat, cooling does
not also activate, and when there is a call for cool, heating does not also activate.
>>If using the configuration of Heat Pump and Furnace with no Common Wire confirm that when
Heat Pump and Furnace are working together (both stages are operating at the same time) that
the display does not go blank, if so you must use a Common Wire.
>>This thermostat is equipped to run with two separated power transformers if required RC and RH.
Terminals RC and RH are internally connected together however you should wish to use two
transformers simply cut with a blade the copper trace on the printed circuit board located
between the C and Y2 screw terminals.
