This programmable thermostat can be used to control an electric
heating system such as an electric baseboard heater, a radiant ceil­ing, a radiant floor, a convector or a fan-forced heater.

NOTE: Always keep the thermostat's vents clean and unobstructed.

o Connect the thermostat wires to the line wires and to the load

wires using solderless connectors for copper wires.

1.

2-wire installation

The thermostat cannot be used with:

• a resistive load over 16.7 A

• a resistive load under 2 A

• a system driven by a contactor or relay (inductive load)

• a central heating system

SUPPLIED PARTS:

• One (1) thermostat

• Two (2) 6-32 screws

• Two (2) solderless connectors

o

Installation

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN
POWER PANEL TO AVOID ELECTRICAL SHOCK. THE INSTAL­LATION MUST BE PERFORMED BY AN ELECTRICIAN.

 All cables and connections must conform to the local electrical

code.

 Special CO/ALR solderless connectors must be used when con-

necting with aluminum conductors.

 Install the thermostat onto an electrical box.
 Install the thermostat about 5 feet high, on an inside wall facing

the heater.

 Avoid locations where there are air drafts (such as the top of a

staircase or an air outlet), dead air spots (such as behind a
door), or direct sunlight.

 Do not install the thermostat on a wall that conceals chimney or

stove pipes.

 The thermostat wires are not polarized; either wire can be con-

nected to the load or to the power supply.

The schedule consists of 4 periods per day which represents a typi­cal weekday. You can program the thermostat to skip the periods that
do not apply to your situation. For example, you can skip periods 2
and 3 for the weekend.

The Comfort ( ) temperature is used in periods 1 and 3 and the
Economy ( ) temperature is used in periods 2 and 4. For example,
when the period changes from 1 to 2, the setpoint automatically

changes from Comfort setting ( ) to Economy setting ( ).
You can have a different program for each day of the week; i.e., each

period can start at different time for each day of the week. The
thermostat has been programmed with the following schedule.

reach a temperature between 95°F (35°C)
and 104°F (40°C).

The measured temperature is below the

During a power outage, LP (Low Power) appears for the first minute.
Then the screen becomes blank. The settings are stored in memory.
However, if the power failure exceeds 4 hours, the thermostat’s clock
must be re-adjusted and, if you are using the automatic Daylight Sav­ings Time changeover function, it must be re-enabled. When power
returns, the thermostat will return to the mode of operation active
prior to the power failure.

The thermal circuit breaker in the heater is
opened. This can happen if the heater is
obstructed by furniture or curtain and has
overheated, or if the thermal circuit breaker
is defective.

The heating system is less than the
