WIRING
INSTALLING THE THERMOSTAT
1. Verify that the thermostat
is suitable for the area
where it is to be installed.
2. Check the line voltage and
the heat-tracing load to
ensure that the thermostat
ratings are not exceeded.
3. Mount the unit in a position that prevents condensation from
draining into the enclosure from the connecting conduit (see
diagram above).
POSITIONING
4. Mount ambient-sensing units in the area exposed to the
coldest temperature and the most wind.
Do not mount on the
side of a warm building or in a location that is exposed to
warm air currents or direct sunlight.
SETTING AND ADJUSTING
5. Set the thermostat dial to the desired temperature and finish
wiring.
