The CDP-2 brings control
and monitoring of your snow melt system indoors. No need to
hope that the system has successfully triggered. One glance at
the CDP-2 confirms it! The CDP-2 is compatible
with both the DS-2B and DS-5 rain/snow sensor
controllers.
The
unit consists of an electronic printed circuit board mounted
securely to a steel mounting plate. The overall dimensions of
the CDP-2 are 4.1"(104) x 1.8"(45)
x 0.9"(23). The unit weighs 2.5 ounces. The CDP-2
fits into a standard single gang or multi gang electrical
enclosure. Compatible self-threading mounting screws that fit
both metal and plastic enclosures are included. The plate also
has mounting holes for a rectangular "modular" cover
plate, similar to the Leviton Decora®
or Hubbell StyleLine™
series. This allows the user to select a cover plate color and
material that blends with the decor of the room.
Wiring is performed by installing a CS-1 remote
control/monitor cable into the DS-2B or DS-5. If
not ordered with the sensor this cable may be ordered with the
CDP-2. A shielded 5 conductor cable is then installed
between the snow sensor and the CDP-2. All signals
between the units are very low voltage so no conduit or
similar protection of the interconnect cable is required. The
individual leads of the interconnect cable are then installed
into the rear terminal block of the CDP-2 and the unit
is ready for operation. The CDP-2 does not
require batteries or an AC power connection. It is actually
powered by parasitic voltage "stolen" from the snow
sensor. Peak power consumption is only 3.5 milliwatts.
Operational temperature range for the electronic components is
-40oC to +85oC. Therefore, the CDP-2
can be installed indoors or outside with proper protection
from the elements.
The CDP-2 allows control of the snow sensor and also
reports the sensor's own override switch position. The
"Manual On" function activates the snow sensor and
controlled equipment to operate for one "delay off"
cycle. The delay off cycle is determined by the DEL switch
setting and the DEL adjustment on the snow sensor, 2 minutes
in "sensor" mode, 30-90 minutes in
"controller" mode. This can be handy for testing and
special operational conditions, like clearing hail buildup,
without the danger of leaving the system in a continuous
"Manual On" condition. The "Automatic"
position allows the sensor to handle all
detections and control. The unit will also always revert to
"Automatic" mode once a "Manual On" cycle
has been completed. A sensor will report activation by
illuminating the "Deice On" indicator. The
"Standby" position disables triggering even in snow
conditions and can also be used to clear the delay off timer
from true or test activation.
An interface is also supplied for connecting a home
automation system to activate the unit for one delay off
cycle. One normally open contact set can be used to trigger
the cycle and a second contact set can be used to provide a
positive "enable" closure for the CDP-2,
reducing the chance of a false trigger. This
"remote/remote" capability can be used to activate a
snow melt system that has been in a long term
"Standby" mode prior to arrival at a vacation home
during winter or when a weather forecast indicates the season
is changing, snowfall is coming, and the system cannot be
manually placed into "Automatic" mode.
Alternatively, the user may connect a pushbutton switch, a
computer-controlled relay, or any other device that can supply
a closure to create a "remote/remote" activation
capability. This can extend control to another room, another
town, or another country!
