Installation
The components of the Basic Digital
Snow Melt Control II
Snow Detector (17002)
Digital Setpoint Control II
with watertight sensor (17029)
Timer Switch (17013)
Timer Face Plate (17014)
Watertight Sensor (17031)
The snow detector should be placed in
a location where it will not be covered
with drifting snow. Install a secure 1/2”
rigid conduit to show a clearance above
ground level of 2 to 3 feet minimum
(depending upon annual snowfall). The
snow detector may also be located on
an exterior wall with full exposure to
snow and ice (no overhang). The snow
detector does not have to be located
near the snow melting area, but should
have full exposure to snow and ice
(away from trees, roof overhangs, etc...).
For proper control, the sensor for the
setpoint control must be located within
the snow melting slab, and should be
placed midway between rows of
tubing. The sensor should be placed in
conduit which is cast into the slab, so
that replacement is possible. The sensor
is extendable up to 100'.
Install the timer in a 3” deep electrical
wall box with “TOP” (indicated on front
cover) in proper position. Fasten cover
to outlet box using two screws provided.
Place calibrated wall plate on timer unit
and fasten with nut provided. Push knob
onto timer shaft. If knob is not centered
on “0”, either the plate or the timer can
be rotated slightly.
