and cycle the De-icer on temperature.
• To bypass the thermostat and operate only on
time, set the thermostat to its highest temperature
setting. Use the timer settings to cycle the de-icer.
Note: If the ambient temperature rises above the
thermostat highest setting, it will shut off the
de-icer.
• When not in use (summer time), store the C-20
indoors away from salt air. This will help extend
the life of the C-20 controller.
• Operate with the door closed to keep salt air away
from internal components.
• Mount the C-20 out of direct sun light. This will
prevent excessive internal heating of the controller.
Internal heating may prevent the C-20 from
operating correctly.

brackish water will freeze somewhere in between.
Setting the thermostat a couple degrees below the
freezing point can minimize unneeded operation
time.
• Daily observation is required for all de-icing
installations. Adjust operating times based on
when you can observe the operation. This will help
you check the de-icer is operating properly.
• Several factors can increase freeze rate. Such
as, wind, snow, and colder temperatures. When
picking operation times, set the de-icer to operate
more when conditions promote quicker freezing.
• Your settings will likely require some ne tuning.
Remember to observe your de-icer installation
and be prepared to adjust your settings of the
C-20. Thermostat tolerance may also need to
be adjusted for. The actual ON/OFF point of the
thermostat may be -/+ 2.7°F of the actual ambient
temperature.
• Operating with fewer, longer cycles will provide
the most efcient de-icing. The following is an
example of setting the timer over a 24 hour period.
The 4 ON cycles below allow for more operating
time during dark hours and less during daytime
hours. (This is suggested due to increased freezing
rate at night).
Cycle Time Length
ON 7:00 a.m. - 9:00 a.m. 2 hr
OFF 9:00 a.m. - 1:00 p.m. 4 hr
ON 1:00 p.m. - 3:00 p.m. 2 hr
OFF 3:00 p.m. - 7:00 p.m. 4 hr
ON 7:00 p.m. - 10:00 p.m. 3 hr
OFF 10:00 p.m. - 12:00 a.m. 2 hr
ON 12:00 a.m. - 5:00 a.m. 5 hr
OFF 5:00 a.m. - 7:00 a.m. 2 hr
This sample would allow the de-icer to operate a
maximum of 12 hours in a 24 hour period. During
the ON cycles, the thermostat would determine if
the de-icer operates based on its dial setting. Actual
settings and durations of run time will depend on your
installation requirements and regional demands for
de-icing.
• To bypass the timer and operate only on
temperature, set the timer ON/AUTO switch to
ON. This will turn the timer output on indenitely #824401 Rev. 02/12/15
