OPERATION INSTRUCTIONS
The GC-1 roof and gutter de-icing controller is designed
to energize the heating cable only when moisture condi-
tions exist and there is risk of freezing. If the tempera-
ture is below 3°C (38°F) and the MSG-1 sensor detects
moisture, the controller will apply power to the heating
cable. The cable remains energized until 3 hours (hold
time) after the sensor is dry. The delay is necessary to
ensure the heated area dries. If at any time moisture
is detected the controller restarts the de-icing cycle.
The optional remote control allows the hold time to
be dialed from 0.5 to 10hrs. There are 2 LED's on the
remote. The top LED indicates the remote is powered
and functioning, the lower gives the status of the GC-1
power relay (heating cables on - energized or off -
de-energized). If the cables are off, pressing the push
button will turn the cables on for the hold time, and
then the control will revert to automatic operation. If
the cables are on, pressing the push button will turn
the cables off, only if the sensor is dry, otherwise the
control will continue to finish the hold time in automatic
operation.
The MSG-1 may be tested for functionality if outside
temperature is below 3°C (38°F). Submerge 2" of the
sensor wire in water, the GC-1 should energize the
heating equipment in the associated zone, the green
LED on the GC-1 will illuminate. After this test, dry the
sensor, the heating equipment in the associated zone
should de-energize after the pre-set hold time.
At the beginning of the heating season and monthly
during operation inspect for and remove all leaves and
combustible debris from roofs gutters and downspouts.
At the beginning of the heating season the MSG-1 must
be inspected for physical damage and the snow sensor
surface cleaned. To clean the snow sensor surface:
1. Lock-out the power supply to the GC-1.
2.
Remove the MSG-1 sensor housing from the gutter.
3. With a clean wet swab clean up the surface of the
snow sensor.
4. Replace the MSG-1 sensor housing in the gutter.
5. Reconnect GC-1 to the power supply.
