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).
DEHUMIDIFY - The process of removing moisture from the air.
DEHUMIDIFIER - Device used to remove moisture from the air.
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.
HUMIDIFIER - A device used to add moisture to a space.
HUMIDISTAT - A control which is operates the humidifier and is affected by changing humidity.
HUMIDITY - Moisture in the air.
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.

Install your PUREPROTM 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.

MOUNTING THE THERMOSTAT TO THE WALL
8PUREPROTM DP732T
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 connec-
tions.
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.

THERMOSTAT OPERATION MODES
18 PUREPROTM DP732T
>>PUREPROTM thermostat can operate in PROGRAM MODE or can HOLD a fixed temperature.
RUN PROGRAM: the thermostat initiates the 7-day Programmable Temperature
Control Program with 4 independent events per day. To set up a custom tem-
perature control program with customizable Temperature Setpoint and Fan
operation mode, refer to Section PROGRAM SETTINGS (page 27).
HOLD TEMPERATURE: the thermostat regulates the room temperature
as determined by the selected Temperature Setpoint.

>>Based on your HVAC equipment PUREPROTM thermostat can operate in the following tem-
perature control modes - AUTO or HEAT or EMERGENCY HEAT or COOL or OFF
AUTO - the thermostat keeps the room temperature between the selected
HEAT and COOL setpoints by using both the cooling and heating HVAC units.
HEAT - the thermostat only turns on the heating units to regulate room
temperature.
EMERGENCY HEAT - the thermostat enables the emergency heat (if
required).
COOL - the thermostat only turns on the air conditioning to regulate room
temperature.
OFF - the thermostat will not control temperature. the thermostat will
continue to display the current room temperature, current room humidi-
ty and outdoor temperature.
TEMPERATURE CONTROL MODES
19INSTRUCTION MANUAL

AUTOMATIC HUMIDITY CONTROL
20 PUREPROTM DP732T
>>In order to reduce condensation, humidity must be controlled and air movement must
be generated. As the exterior temperature drops, the humidity level needs to decrease if
condensation is to be controlled.
HUMIDITY AUTO: the thermostat automatically adjusts the humidity set
point based on the current indoor temperature and humidity as well as
the current outdoor temperature in order to maintain a maximum com-
fort level and eliminate condensation. The automatic humidity setpoint is
determined according to the following standard humidity table.1
Setpoint Outdoor Temp in °C Outdoor Temp in °F
15% -29°C -20°F
20% -24°C -10°F
25% -18°C 0°F
30% -12°C 10°F
35% -7°C 20°F
40% -7°C -20°F
HUMIDITY MANUAL: The user selects the humidity setpoint.
