1. Description
The electronic thermostat STE302NP can be used to
control electric heating units such as electric base-
boards, 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 copper
wires.
2. 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:
