n Description

This thermostat can be used to control an electric heating system such as a baseboard heater, a radiant ceiling, a radiant floor, a convector, etc.

The thermostat cannot be used with the following:

•a resistive load under 2 A

•a resistive load over 12.5 A

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

•a fan-forced heating system (e.g.: fan-forced convector)

•a central heating system

SUPPLIED PARTS

•One (1) thermostat

•Two (2) 6-32 mounting screws

•Two (2) solderless connectors

o Installation

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

Loosen the screw holding the control module to the base. The screw cannot be completely removed. Lift the control module to remove it from the base.

Make the appropriate connections. Please note that the thermostat wires are non-polarized; either wire can be connected to either terminal.

NOTE: All cables and connections must conform to the local electrical code. Special CO/ALR solderless connectors must be used when connecting with aluminium conductors.

2-wire installation

4-wire installation

Align and affix the base to the electrical box.

NOTE: Before installing the thermostat base, install provided adapter plate (U-shaped) on 347V electrical box which is bigger than regular electrical boxes.

Set the switch at the back of the removable part of the thermostat to °C or °F.

Replace the front part of the thermostat on the base and secure it in place with the screw.

NOTE: Keep the air vents of thermostat clean and unobstructed at all times.
