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 o 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 eective and
constant solution to protect your roof from ice dam or related hazards. The quality
engineered RX heating cables provide a safe, exible 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 eect 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
re 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, re 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.
