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.

1. Make sure to turn off the power supply located at the electrical service panel.
All heating and cooling units should be OFF.
2. Separate the backplate from the thermostat by grasping the unit firmly at the
bottom lip and pulling gently until the two piece are apart.
3. Align the backplate to the wall.
4. Mark the three locations for drilling the 3/16” holes required for the plastic
screw anchors.
5. Remove the backplate and drill the three 3/16” holes in these locations.
6. Insert the plastic gyproc screws and ensure that they are snug in the wall.
7. Securely mount the backplate to the wall with the 3 supplied screws.
8. Make the appropriate wire connections based on the specifications of the
household HVAC unit(s). Please refer to Wiring Table to determine the appropriate
wire connections.
9. Place the thermostat on the backplate by firmly but gently from the top aligning
the pins with the screw terminals.
10. Turn on the electricity at the electrical service panel.

TEMPERATURE CONTROL MODES
17
>> Based on your HVAC equipment TrueTouch™ thermostat can operate in the
following temperature control modes - AUTO or HEAT or EMERGENCY HEAT
or COOL or OFF.
AUTO - Keeps the room temperature between the selected HEAT
and COOL setpoints by using both the cooling and heating HVAC
units.
HEAT - Only turns on the heating units to regulate room temperature.
EMERGENCY HEAT - Enables the emergency heat (if required).
COOL - Only turns on the air conditioning to regulate room
temperature.
OFF - Will not control temperature. The thermostat will continue to
display the current room temperature, current room humidity and
outdoor temperature.
THERMOSTAT OPERATION MODES
16
>> TrueTouch™ thermostat can operate in PROGRAM MODE or can HOLD a fixed
temperature.
RUN PROGRAM: Initiates the 7-day Programmable Temperature
Control Program with 4 independent events per day. To set up a
custom temperature control program with customizable
Temperature Setpoint and Fan operation mode, refer to Section
PROGRAM SETTINGS (page 27).
HOLD TEMPERATURE: Regulates the room temperature as
determined by the selected Temperature Setpoint.

19
>> TrueTouch™ thermostat can operate the fan in one of the following three modes:
FAN AUTO: The fan runs only when there is a demand for heating
or cooling.
FAN ON: The fan runs continuously
FAN INTERMITTENT: The fan runs 10 minutes per 1/2 hour
providing a convenient way to improve air quality and save energy.
When the fan is running, the animated fan icon will
appear on the HOME SCREEN.
