SETTING THE CONFIGURATION SWITCHES AND ADJUSTMENTS
The following paragraphs and table outline the operating modes
for the DS-8C and explain the functions of the adjustments. Trigger
temp (TT) is adjustable from 34°F-44°F (1°C-6°C) using the TRIG
TEMP control.
When ambient air temperature (AT) is below this setting precipitation
is assumed to be snow. When above this setting, precipitation is
assumed to be rain.
These are just some of the possible wiring schemes that can be
used to connect the DS-8C to your load for control.
Remember, these are only suggestions. You should always consult
a qualified electrician or inspector to assure conformance with
applicable local and national electrical codes!
The Low Temperature Cutoff (LTC) option is typically used on snow melting
systems with limited output capacity where melting cannot be maintained at
very low temperature. If selected, the snow sensor will clear a trigger below
5°F (-15°C) even if snow is still falling. It will resume normal operation above
9°F (-13°C). However, the sensor will remember if it was triggered before the
drop below 5°F or if snow was detected during the cold period. If so, the sensor
will execute one Delay-Off cycle when the temperature rises above 9°F in
order to melt any snow left behind during the cold period. This is referred to
as RECOVER mode.
Care should be exercised in using this mode as the potential exists for ice to be formed on the melting
surface.

DS-8C RAIN/SNOW SENSOR CONTROLLER
INSTALLATION INSTRUCTIONS
™
The DEL configuration switch activates the Delay-Off drying cycle timer on
the DS- 8C. The timer allows the DS-8C to continue to operate and dry the
heated surface through evaporation once precipitation has stopped. The
drying cycle reduces the chance of moisture left behind refreezing into ice.
This timer is restarted by each sensor trigger. Therefore, the DS-8C will
continue to operate as long as it is triggered, then for the Delay-Off period
once the trigger clears.
All "sensor" modes (DEL Off) provide a 2 minute Delay-Off time. When
in "controller" mode (DEL On) the Long Delay (LD) configuration switch
determines the time span of the drying cycle. The Delay-Off time can be
adjusted from 30- 90 minutes (LD Off) or 2-6 hours (LD On) using the
