Contactor Pro Owner's Manual

For ProMelt CP-50, CP-100, and CP-200
Panels
The CP-50, CP-100, and CP-200 are turn-key panels for activating a
ProMelt snow melting system when used in conjunction with the ProMelt
series of controls. They allow simple connection from the circuit breaker
panel and have a manual override timer and heating indicator. Any CP
series panel can be used as an "extension" panel that connects to
another CP series panel and allows additional circuits to be controlled.
Specifications
Features
Each ProMelt system can be used with a wide variety of
moisture/precipitation sensors, including the following:
Slab Mounted: PM-HSC5
Pole/wall Mounted: PM-224 and PM-824
Each sensor option is designed to operate a single system.
Use a dedicated sensor and CP panel group for each snow melt zone.
CP series of panels can be used directly with any ProMelt cable or
mat system. Power is connected directly to each contactor in the panel.
It is pre-wired to the included transformer, terminal blocks, and the coil
terminals on the provided contactors. It is not recommended to unwire,
or tamper with existing wiring without pre-authorization from the factory.
