INSTALLATION
OUTDOOR SENSOR INSTALLATION
•
Only use the Heat-Timer sensor included with the unit (HT# 904220–00).
•
Locate the sensor in the shade on the north side of the building. The sensor
should never be in direct sunlight.
•
Be sure the location is away from doors, windows, exhaust fans, vents, or other
possible heat sources.
•
The sensor should be mounted approximately 10’ feet above ground level.
•
Adhere the Outdoor Label provided to the back of the sensor base.
•
Use the Enclosure Base bottom knockout for the conduit. Use the locknut to
hold the conduit and enclosure base together. Screw the cover to the base.
•
If screws are used to affix the enclosure to the wall, make sure to seal around the
sensor and wall except from the bottom.
•
The sensor wires can be extended up to 500’ using shielded 2-conductor cable
(#18/2). Do not ground the shield at the sensor but at the control using the
terminal marked with an “O”.
•
Do not run sensor wires in conduit with line voltage wiring.
ALERT
Determining the proper location of the outdoor sensor is very important. The Genesis Heat-Timer
®
will base the heat
output on the outdoor temperature information it receives from this location. If the sensor is in the sun, or covered with
ice, its reading will be different from the actual outdoor temperature (OD).
