CAUTION:
• Installation must be carried out by a certified electrician and must comply with national and
local electrical codes.
• Use this thermostat for resistive loads only.
• Do NOT install the thermostat in an area where it can be exposed to water or rain.
• To prevent severe shock or electrocution, always turn the power Off at the service panel
before working with wiring.
• Install the thermostat onto an electrical box.
• Use special CO/ALR solderless connectors if you connect the thermostat to aluminum wires.
• Keep the thermostat's top and bottom air vents (openings) clean and unobstructed at all
times.

nInsert the floor sensor cable through one of the two
openings on the wallplate and connect the sensor
wires to terminals 1 and 2 (no polarity).
• The sensor cable must not come in contact with the
electrical wires and must be routed outside the
electrical box and follow the wall down to the floor.
• Position the sensor cable such that it does not
come in contact with the floor heating wires. The
sensor must be centered between two floor heating
wires for best temperature control.
• Do NOT staple the sensor head (the plastic end) to
the floor. Doing so might damage the sensor. Any
damage might not be noticeable during testing but
can become apparent several days later.
oIf you wish to connect a remote control device (see
page 17), insert the wires (use 18- to 22-gauge flexible
wires) through one of the two openings on the wallplate
and connect them to terminals 2 and 3 (no polarity).

1. Early Start is used in Automatic mode only. When Early Start is enabled (on), the thermostat determines when to start
heating so the Comfort temperature is attained at the beginning of periods 1 and 3. When Early Start is disabled (off),
heating starts only at the beginning of periods 1 and 3; thus there is a delay before the Comfort temperature is
reached.

The schedule consists of 4 periods per day, which represents a typical work day. The Comfort ( ) preset
temperature is automatically used in Periods 1 and 3 and the Economy ( ) preset temperature in Periods
2 and 4. You can program the thermostat to skip (cancel) the periods that do not apply to your situation. For
example, you can skip periods 2 and 3 for the weekend.
NOTE: If you wish to use only 2 periods, use the following combinations: “1 and 4” or “2 and 3”. Early Start
(see page 9) will not work with any other combinations.
You can have a different program every day; i.e., each period can start at a different time every day. The
thermostat has been programmed with the following schedule.

ENGLISH
This ground fault protection thermostat is different from conventional thermostats. In the event of a ground
fault, the ground fault protection mechanism on the thermostat will trip and quickly stop the flow of
electricity to prevent serious injury.
Definition of a ground fault
Instead of following its normal safe path, electricity passes through a person’s body to reach the ground.
For example, a defective floor heating mat can cause a ground fault.
A ground fault protection thermostat does not protect against circuit overloads, short circuits, or
electrical shocks. For example, you can still receive an electrical shock if you touch bare wires while
standing on a non-conducting surface such as a wood floor.
Ground fault protection reset
When the ground fault protection mechanism trips, the TEST light is On (red). To reset the ground fault
protection, switch the thermostat to Off and back to On. The TEST light will turn off.
Ground fault protection (GFCI)
