1. Description
The electronic thermostat STE403NP can be
used to control electric heating units such as
electric baseboards, convectors, or aerocon-
vectors. It keeps the temperature of a room at
the requested set point with a high degree of
accuracy. This product is designed for instal-
lations with electrical current - with a resistive
load - ranging from 1.2 A to 16.7 A (400 to
5750 W at 347 VAC).
This thermostat is not compatible with the
following installations:
• electrical current higher than 16.7 A with a
resistive load (5750 W @ 347 VAC);
• electrical current lower than 1.2 A with a re
-
sistive load (400 W @ 347 VAC);
• inductive load (presence of a contactor or a
relay); and
• central heating system.
Parts supplied:
• one (1) thermostat;
• two (2) mounting screws; and
• two (2) solderless connectors suitable for
copper wires.
