Installation Parameters
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.
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 this cable by removing 2 inches of
outer jacket and shield, then strip 1/4" (6.4 mm)of the insulation from
the conductors. Attach one end of this cable to the free end of the CS-1
Pigtail, noting any color code change in the table.

ENGINEERING
Following this table, attach the other end of this cable to the terminal
block labeled TB1 on the PM-DP. To do this, press the clamp button on the
terminal block, insert the bare wire end, then release. Lightly tug on the
wire to ensure it is connected.
Use terminals 1-4 on TB1 when connecting to a Home Automation
System (HAS). Closure of terminals 1-2 (Trigger) and 3-4 (Enable) will
start one snowmelting 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 HAS. If a secondary toggle switch is not used, jumper
terminals 3-4 to all the HAS to enable the system as needed.
PM-DP wired to a PM-2B with the use of a CS-1 jumper.
