GLOSSARY OF TERMS

CYCLE RATE - Cycle rate is the frequency that heating or cooling equipment is turned on during a

certain period of time. Cycle rate is often given in units of cycles per hour (CPH).

DIFFERENTIAL - Differential is defined as the difference between the cut-in and cut-out points as

measured at the thermostat under specified operating conditions. For example, if the thermostat

turns the heating equipment on at 70 degrees F and turns the heating equipment off at 74 degrees

F, then the differential is 4 degrees F.

PROGRAMMABLE THERMOSTAT - A thermostat with the capability of automatically adjusting tem-

perature set point to pre-selected settings at pre-selected times.

SETBACK - The automatic alteration of the thermostat control point(s) by means other than man-

ually changing the temperature set point.

SET POINT - The desired temperature setting on an electromechanical or electronic thermostat.

ADVANCED SETTINGS - DUAL FUEL SWITCH

IMPORTANT: This feature can only be activated when used with the LUXPRO^®Outdoor

Wireless Temperature Transmitter and Receiver. Please install the LUXPRO^®Outdoor

Wireless Temperature Transmitter and Receiver before activating this feature.

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.

dependent on the type of system you have configured.

•

1ST STAGE DIFFERENTIAL: Set temperature difference between temperature set point and

actual temperature reading before 1st stage heating or cooling is initiated.

2ND STAGE DIFFERENTIAL: Set temperature difference between 1st stage initiation and 2nd stage

heating or cooling initiation.

OB ENERGIZED: Reverses the Heat Pump OB Valve contact to HEAT or COOL (manufacturer

dependent).

LUXPRO^®PSPU721T

ADVANCED SETTINGS - TIMER FEATURE

•

Specify the number of minutes for which Stage 1 will function until Stage 2 is activated to help

raise (or cool) temperature (if the temperature set point is not reached). This unique function

avoids excess compressor wear in the case where the necessary temperature set point is not met

through setting of the Staging Differential. Set to “00” to disable.

INSTRUCTION MANUAL

ADVANCED SETTINGS - HEAT PUMP

•

HP ON when Furnace On: Heat Pump and Furnace can operate together when 2nd stage fur-

nace is required. HP “OFF” when Furnace On: turns off the Heat Pump when the furnace is On

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

LUXPRO^®PSPU721T

TROUBLESHOOTING

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 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.

INSTRUCTION MANUAL

IMPORTANT NOTICE

>> 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

does not switch on.

>> If test A or B fail or the thermostat shuts down in either HEAT or COOL MODE then it is neces-

sary to connect a common wire, (C), alternatively it may be possible to solve this issue by sim-

ply 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.
