Operation Instructions Post-heating If the reason for ending a heating period is a decrease of moisture to below the chosen level, the post-heating period will start. Post-heating ensures that no ice and snow is left on the ground.
If system priority is low, heating might be paused at any time! The ground system uses heated sensors which under normal circumstances
will hold a temperature of 35°F (1.5°C). In connection with measuring the area tempera- ture heating of the sensor is turned off for 90 minutes at a time. This is done in order to obtain a correct measurement of area temperature which is not infl uenced by sensor temperature. If a system only has one sensor this sensor is constantly heated for 90 minutes and then turned off for 90 minutes. This entails that measurement of tem- perature can be up to 3 hours delayed. With more than one sensor this performance is signifi cantly improved.
Security and energy consumption High security – higher energy consumption If a high degree of security against ice and snow is wanted, make the following adjust- ments of the operation parameters: • Increase the standby temperature • Increase the melting temperature • Decrease the moisture level (close to setting 5) • Prolong the post-heat period This will give a high degree of security in even dry areas. Low security – lower energy consumption Conversely, low energy consumption and a moderate level of security against ice and snow could be prioritized. In this case make the following adjustments of the operation parameters: • Decrease the standby temperature • Decrease the melting temperature • Increase the moisture level • Shorten the post-heat period This will give relatively low energy consumption, but the area may remain wet and icy in short periods.
The factory settings are average values providing a relatively high degree of
security and moderate energy consumption.

System overview The GX™ 850 system is capable of keeping outdoor areas free of ice and snow. The GX™ 850 can handle up to 2 independent areas, in any of the following combinations: • Single roof system
To keep gutters, valley gutters and down pipes free of ice and snow, and to prevent ice dams from causing damage. It is also possible to use the roof system to reduce/remove the snow weight from a roof. (Roof system A)
• Single ground system
To keep areas like parking areas, paths, garage entrances, steps, ramps, roadways and bridges free of ice and snow. (Ground systems A)
• 1 ground system and 1 roof system
(combi system) Consists of 1 single roof system A and 1 single ground system B.
• 2 roof systems (dual system)
Consists of 2 x “Single roof systems (A and B)”.
• 2 ground systems (dual system)
Consists of 2 x “Single ground systems (A and B)”.
