FINE ADJUSTMENT FOR EFFICIENT OPERATION
The DS-2C is shipped with the TRIG TEMP and DELAY OFF adjustments in the center position, representing
39°F (3.9°C) and 60 minutes of Delay-Off time respectively. It is also set for highest SENSITIVITY. Depending
on local conditions the user may find that fine adjustment of the controls may provide more satisfactory
operation. If the sensor does not trigger during very wet snows the trigger temperature may need to be
adjusted higher. Constant triggers from snow falling from trees or overhangs may be reduced by adjusting
SENSITIVITY. The Delay-Off time can also be adjusted to provide clean melt-off without excessive running
time. Fine adjustment can both save operating expense and provide more reliable operation. However, to
keep reliability high, always make adjustments in small increments.
Use Care When Replacing the Front Cover. Do Not Pinch the Gasket or Overtighten the Screws.
MANUAL OVERRIDE SWITCH OPERATION
An override switch mounted on the side is provided for testing and special operational requirements.
Placing the switch in the AUTOMATIC position will allow the sensor to operate normally, activating the
controlled equipment as needed. Placing the switch in MANUAL ON will close the load relay, activating the
controlled equipment. The “STANDBY/RESET” position prohibits triggering of the unit, clears any active
delay timer, and opens the load relay. In order to reduce excessive runtime for the heater the “Manual
On” mode will remain in effect for up to 40 hours, then return to “Automatic” mode, even if the switch
is still in the “Manual On” position. However, any trigger of the system will restart the 40 hour “Manual
On” timer. You may put the DS-2C back into “Manual On” mode by switching to AUTOMATIC, then back to
MANUAL ON. This will also restart the 40 hour timer.
If the override switch is placed in MANUAL ON for less than 2 seconds, then switched back to AUTOMATIC
the controller will execute one Delay-Off cycle. This can be used to clear a frost, hail, or drifted snow
buildup without the danger of leaving the system in a continuous “Manual On” condition.
“Standby/Reset” can still be used to clear this Delay-Off cycle.
