1. Description

This programmable electronic thermostat can be used to control electric heating units such as electric baseboards, convectors, or aeroconvectors. It keeps the temperature of a room at the requested set point with a high degree of accuracy. This product is designed for installations with electrical current – with a resistive load – ranging from 1.25 A to 12.5 A (120/240 VAC). It possesses a user-friendly interface. Furthermore, it gives you the possibility to control the temperature of a room with great precision. This thermostat is not compatible with the following installations :

Electrical current higher than 12.5 A with a resistive load (3000 W @ 240 VAC and
1500 W @ 120 VAC);
Electrical current lower than 1.25 A with a resistive load (300 W @ 240 VAC and 150
W @ 120 VAC); and
Central heating system.
Parts supplied:
one (1) thermostat;
wall mounting plate located at the back of the thermostat;
two (2) mounting screws;
two (2) solderless connectors suitable for copperwires.

2. Installation

The thermostat must be mounted to a connection box on a wall facing the heating unit, at around 1.5 m (5 feet) above the floor level, on a section of the wall exempt from pipes or air ducts. Do not install the thermostat in a location where temperature measurements could
be altered. For example:

close to a window, on an external wall, or close to a door leading outside;
exposed directly to the light or heat of the sun, a lamp, a fireplace or any other heat
source;
close or in front of an air outlet;
close to concealed ducts or a chimney; and
in a location with poor air flow (e.g. behind a door), or with frequent air drafts (e.g.
head of stairs).

Thermostat mounting and connection

Cut off power supply on lead wires at the electrical panel in order
to avoid any risk of electric shock.
Ensure that the air vents of the thermostat are clean and clear of any obstruction
Using a screwdriver, loosen the screw retaining the mounting base of the
thermostat until it is loose (do not completely remove the screw).Then, remove the mounting base at the back of the thermostat by pushing it
downwards and then towards you.
Align and secure the mounting base to the connection box using the two screws supplied.
Pass the wires from the wall through the opening on the mounting base and connect them using the supplied solderless connectors. When making the connection with aluminum wire, make sure that you are using connectors identified CO/AL. Please note that the thermostat wires do not have polarity. Therefore, the way they are connected is not important.
Place all the wires into the connection box.
Align the little slots located on the top of the thermostat with those on the
mounting base and secure the thermostat to the mounting base. Note that you can also position the thermostat on the left or the right side of the junction box. Then, tighten the screw at the bottom of the unit.
Turn on the power.
Set the thermostat to the desired setting (see the following section).
