Instructions for Installing PM-DP
Remote control panel
The PM-DP provides direct remote operation for the PM-2B, PM-5,
PM-224, and PM-824 snow sensors. Users can monitor both the oper-
ating mode and the activation state of the sensor. Additional control
features include setting automatic, manual, or standby operation.
Installation
Install the PM-DP remote switch in a single gang box. The PM-DP may be
installed in a conventional single or multi-gang electrical enclosure.
If installed in a multi-gang enclosure next to high voltage equipment, the
PM-DP and its interconnecting cable must be isolated from high voltage
wires and devices. Consult local electrical codes to determine the isolation
method(s) required. The PM-DP can be installed up to 800 feet away from
the snow sensor.
• Remove all power to the sensor and open the cover
• Plug the CS-1 Pigtail into the jack labeled J3 on the snow sensor
circuit board.
• Cut the required length of 5 or 6 conductor, minimum 22 AWG
shielded cable.
• Prepare both ends of the conductor cable by removing 2 inches of
outer jacket and shield, then strip 1/2" of the insulation from
the conductors.
• Attach one end of the conductor cable to the free end of the CS-1
Pigtail inside a weatherproof junction box noting any color code change
in the table.
• Following the color code table, attach the other end of this cable
terminals 5 through 9 of the terminal block labeled TB1 on the PM-DP,
making sure to connect the noted color to the proper terminal.
• Secure the wires to the TB1 connectors by pressing the clamp button
on the terminal block and inserting the bare wire end and then
releasing the button.
• Lightly tug on the wire to endure the wire is securely connected.
• To reduce the chances of damage due to static shock, ground the
PM-DP faceplate by removing 1 inch of insulation from the green EGND
lead and connecting this lead along with the bare "drain" wire, in the
long 5 or 6-conductor 22 AWG shielded cable, to an electrical ground
lead using a wire nut or equivalent.
Home Automation
Use terminals 1-4 on TB1 when connecting to a home automation
system. Closure of terminals 1-2 (Trigger) and 3-4 (Enable) will start one
snow melting cycle. Once the cycle is completed the sensor will revert to
Automatic mode.
Connect a toggle switch to the Enable
terminals to allow manual enabling and
disabling of the home automation system.
If a secondary toggle switch is not used,
jumper terminals 3-4 to allow the home
automation system to enable the system
as needed.
PM-DP fits directly into a single-gang box and
can be fitted with a standard "modular" elec-
trical cover plate. A CS-1 pigtail is included
with the PM-DP.

WARNING: General Safety Instructions
1. THIS UNIT SHOULD BE INSTALLED ONLY BY
QUALIFIED PERSONNEL!
2. Disconnect all power from the control, or any associated equipment,
before opening the front cover plate.

Operation
The LED indicators reflect the current operating mode of the snow sensor
and snow melting system. The LED's blink periodically rather than
remaining steadily illuminated.
• The Deice On indicator shows whether or not the attached snow
sensor has been activated and the snow melt system is operating. It may
illuminate either from automatic activation of the sensor or by the user
pressing the Manual On button.
• Pressing Standby will set the connected snow sensor to ignore snow
fall and prohibit automatic operation of an attached snow melt system.
• Pressing Automatic will set the connected snow sensor to
automatically activate and control an attached snow melt system when
snow is detected.
• Pressing the Manual On button will not trigger the sensor to run
continuously but will initiate one drying cycle. This function allows the
user to run a cycle without having to remember to shut the system off.
At the end of the drying cycle the system will revert to Automatic mode,
ready for detection. The user may reset and clear the drying cycle by
pressing Standby. Typically a drying cycle time is configured on the snow
sensor with a delay of 30-90 minutes. It begins once snow stops falling
and allows the heated surface to more thoroughly dry.
The PM-DP will display the current setting of the manual override switch
for the attached snow sensor. The sensor's override switch will always take
precedence over the PM-DP setting. For example, if the PM-DP has placed
the sensor into Standby mode and the sensor switch is moved Manual On,
the PM-DP will show the change to Manual On mode.
Whenever the sensor's switch overrides the PM-DP's setting, then is
returned to Automatic Mode, the PM-DP will revert to the Automatic Mode
as well.
