Summit Ice Melt System’s CDC+ Controllers

A popular residential and small commercial controller is our CDC+ Series Digital Controllers. They are advanced digital controllers that use a thermistor to determine ambient temperatures.  When the outdoor temperatures drop below a set temperature, the system is automatically energized.  When the outdoor temperature warms again, the system shuts off.

  • Model 4CDC+ Up to 4 30A circuits (120Vac – 277Vac)
  • Model 8CDC+ Up to 8 30A circuits (120Vac – 277Vac)
  • Model 12CDC+ Up to 12 30A circuits (120Vac – 277Vac)

The 4-, 8-, and 12-CDC+ Features:

● Summit Ice Melt Systems’ CDC+ controllers are the perfect match to any residential or small commercial Summit Ice Melt System installation. They provides ambient temperature sensing digitally controlled operation for up to 12 separate heating zones with 30A circuits each.

● The digital readout provides a very user-friendly interface, and allows variations in programming to meet local conditions.

● Set the controller to “Auto” mode and the system triggers when the temperature drops below a pre-set, field-adjustable temperature setting.

● Set the controller to “Manual” mode for testing and manual operation

● The controller can be programmed for low-temperature cutoff.

● The indicator light lets you know when the system is energized.

● The ambient temperature sensor is mounted outdoors in an area typical of the coldest conditions, usually on the north exposure of the building. A built-in alarm notifies the operator if there is an error with the probe or short or open sensor leads.

● The CDC+ “Plus” designation utilizes ALL-CONTACTOR protection of its circuits to snap off BOTH bus wires for greatest safety.

● The controllers are engineered and perfected by our Certified UL 508 panel building shop to ensure top performance and safety.

● The controllers provide On/Off/Manual operation of its S1 and S2 (120Vac to 277Vac) 12 watt/foot and EverClear 812 and 822 (120Vac to 277Vac) 8 watt /foot self-regulating heater cables for Summit Systems by energizing up to four individual branch circuits. Each branch circuit must be protected by a ground fault protection device per the NEC. A 120Vac protected circuit is required to energize the controller. NEMA 4/12 (exterior installation) enclosures are standard.
