Installation instruction
When more than 1 area is controlled by the ECtemp 850 system, it is also possible to
prioritize the areas. Prioritizing makes it possible to operate 2 areas, even if the needed
power for 2 areas is not present.
The ECtemp 850 is fully automatic and operated digitally by means of the intelligent
sensors located in the heated terrain. Each sensor measures both temperature and
moisture, and the system turns the heating elements on and off based on these read-
ings. 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 ECtemp 850 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 measure-
ments 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 sen-
sors are recommended.
For more information please refer to the sensor
manual.
