Installation Instruction
When more than 1 area is controlled by the GX-850M ver. IV system, it is also possible to prioritize the
areas. Prioritizing makes it possible to operate 2 areas, even if the required power for 2 areas is not
present.
The GX-850M ver. IV is fully automatic and operated digitally by means of the intelligent sensors locat-
ed in the heated terrain. Each sensor measures both temperature and moisture, and the system turns
the heating elements on and off based on these readings. By combining moisture and temperature
readings, the system is able to save around 75% energy compared to systems which only measure
temperature readings. The digital sensors used for the GX-850M ver. IV also provide the most exact
readings when compared with corresponding analogue systems. The result is optimum functionality
and low energy consumption.
A typical installation consists of:
•
Controller unit (only one)
This is the device which, based on the measurements from
the sensors, decides when to heat the connected area(s).
•
Power supply (one or more)
The power supply delivers power to the controller unit and
the connected sensors.
•
Ground sensor (one or more)
At least 1 ground sensor is needed for each ground area, but
to get the best performance of a system, 2 or more sensors
are recommended.
For more information please refer to the sensor manual.
•
Roof sensor (one or more)
At least 1 roof sensor is needed for each roof area, but for
complex roof constructions, 2 or more sensors are recom-
mended.
For more information please refer to the sensor manual.
