RX1200 - ROOF AND GUTTER DE-ICING CONTROLLER
Introduction
The RX1200 controller is designed to use in conjunction with Danfoss roof and gutter de-icing cable for roof, gutter and snow melting applications, such as Danfoss RX cables. The RX1200 sense both moisture and temperature conditions in the gutter or downspouts and turns the roof de-icing cable on and off based upon these readings.
By combining the moisture and temperature readings, the controller is able to save up to 75% on energy consumption compared to a controller which only measure temperature.
Danfoss RX products – cables and controls are designed to produce an effective and constant solution to protect your roof from ice dam or related hazards. The quality engineered RX heating cables provide a safe, flexible and economical solution of you snow and ice protection needs.
The RX1200 is rated at a maximum of 10.2 Amps at 120 Volts, which means the maximum cable wattage the can be connected to the controller is 1225 Watts. Only one roof and gutter de-icing cable can be connected to the RX1200 by a grounded plug. Remember that self-regulating cables can get higher effect when turned on in cold weather.

WARNING
1.It is required the circuit supplying power to the RX1200 and heating cable have ground fault protection. This is mandatory by National/Canadian Electric Code.
a.If the ground fault trips and cannot be reset, then there is a fault in either the RX1200 or the heating cable.
b.Do not attempt to bypass the ground fault device. Doing so may result in risk of fire or electrical shock.
2.The RX1200 must be kept dry. The RX1200 is not water resistance and will fail if the device gets in contact with water, snow or ice.
3.Roof and Gutter cables must be installed in compliance with either National or Canadian Electric Code and Local or Provincial Code
4.Only one roof and gutter cable per RX1200. Do not exceed 1225W on the RX1200; risk of electric shock, fire or the formation of ice dams can result if more than 1225W or more than one cable is connected to the RX1200.
5.The RX1200 must be installed according to the manufacturer’s instructions. By not doing so may void your warranty.
6.Make sure to save this manual in case assistance is needed in the future.
