The multiple programming electronic thermostat STE402P+ 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 elec-
trical current – with a resistive load – ranging from 1.25 A to 16.7 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 16.7 A with a resistive load (4000 W @ 240 VAC and 2000 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 copper wires.
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 oor 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 replace 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 ow (e.g. behind a door), or with frequent air drafts (e.g. head of stairs).
