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 temperature set point to pre-selected settings at pre-selected times.
SETBACK - The automatic alteration of the thermostat control point(s) by means other
than manually changing the temperature set point.
SET POINT - The desired temperature setting on an electromechanical or electronic
thermostat.
Install your TrueTouch™ thermostat approximately 5 feet (1.5 meters) above the
floor in an area with good air circulation.
Avoid the following locations:
•Hot or cold air from ducts
•Radiant heat for appliances or sun such as a skylight
•Unheated or uncooled areas: for example an outside wall behind the thermostat.
•Ensure that there is no furniture directly below or beside the thermostat.

ADVANCED SETTINGS - DUAL FUEL SWITCH
31
!IMPORTANT: This feature can only be activated when used with the
TrueTouch™ Outdoor Wireless Temperature Transmitter and Receiver.
Please install the TRUETOUCH™ 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 assis-
tance to an outside temperature of just a few degrees below freezing. This tem-
perature 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.
•HP Cut ON or OFF
•Cut Temperature:
+/-Temperature in Celsius (-5°c to 25°c)

ADVANCED SETTINGS - SYSTEM CONFIGURATION
30
!IMPORTANT: By inadvertently modifying system configuration settings, you
may seriously degrade HVAC system performance.
>> Choose system heating and cooling equipment - remember all you need to do is toggle
the appropriate button until the correct setting appears.
• Choose HEAT PUMP or AIR CONDITIONING or NO COMPRESSOR - please
review the wiring table and diagram for wiring instructions.
• Choose FURNACE OFF (No Furnace) or ELECTRIC FURNACE or GAS FURNACE or
OIL FURNACE or 2 STAGE GAS FURNACE; please review the wiring table and
diagram for wiring instructions.
• Cycle Rate: Set Maximum compressor cycles per hour. We recommend that the
factory default be maintained for optimal performance..
• AUTO CHANGE: Set the minimum difference between Auto Mode, Heat and Cool
temperature setpoints. We recommend that the factory default be maintained for
optimal performance.

ADVANCED SETTINGS - TIMER FEATURE
33
• 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.
ADVANCED SETTINGS - DIFFERENTIAL SETTINGS
32
>> The TrueTouch™ TSZ-1 allows you to control up to 2 Stages of Heating and
1 Stages of Cooling, 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
•OB ENERGIZED: Reverses the Heat Pump OB Valve contact to HEAT or COOL
(manufacturer dependent).

ADVANCED SETTINGS - HEAT PUMP
•HP ON when Furnace On: Heat Pump and Furnace can operate together when 2nd
stage furnace is required. HP OFF when Furnace On: turns off the Heat Pump when
the furnace is On (required on some gas or oil furnaces).

>> Calibration of Temperature
TrueTouch™ Thermostat is rated for an accuracy of +/-1°F (+/-0.5°C).
If you have determined due to drafts, sunlight or other environmental factors that your
thermostat requires calibration, follow this easy guide. Common cause of offset are lack
of air circulation, drafts or skylights in the direct vicinity of the thermostat.

TROUBLESHOOTING

for 1 minute for the thermostat to automatically lock.
?Thermostat appears normal until the screen becomes blank when the com-
pressor or heating system turns on. You need to connect the “C” wire.
