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, etc.

The thermostat cannot be used with the following:

• a resistive load greater than 16.7 A

• a resistive load less than 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

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK.

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.
