1. Description
The electronic thermostat STE402NP 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 1.2 A to 16.7 A
(150 to 2000 W at 120 VAC, 260 to 3475 at 208 VAC
and 300 to 4000 W at 240 VAC).
This thermostat is not compatible with the
following installations
• electrical current higher than 16.7 A with a resis
-
tive load (4000 W @ 240 VAC, 3475 W @ 208 VAC
and 2000 W @ 120 VAC);
• electrical current lower than 1.2 A with a resistive
load (300 W @ 240 VAC, 260 W @ 208 VAC and
150 W @ 120 VAC);
• inductive load (presence of a contactor or a relay);
• central heating system.
Parts supplied:
• one (1) thermostat;
• two (2) mounting screws;
• two (2) solderless connectors suitable for copper
wires.
2. Installation
Selection of thermostat location
The thermostat must be mounted on 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 draft conditions (e.g. head of stairs).
Note:
This handling description is printed prior to product
development. When a part of the product specification
must be changed to improve operability or other func-
tions, priority is given to the product specification it-
self. In such instances, the instruction manual may not
entirely match all the functions of the actual product.
Therefore, the actual product and packaging, as well as
the name and illustration, may differ from the manual.
