Description

This programmable electronic thermostat can be used to control electric heating units such as electric baseboards, convectors, or aero convectors. 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 copperwares.

Installation

Selection of the thermostat location
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

1. Cut off power supply on lead wires at the electrical panel in order to avoid any risk of electric shock.
2. Ensure that the air vents of the thermostat are clean and clear of any obstruction.
