0 The factory settings are average values providing a relatively high degree of security and moderate energy consumption. Low security – lower energy consumption Conversely, low energy consumption and a moderate level of security against ice and snow could be prioritized.
Ground system When more than 1 area is controlled by the GX™ 850 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. For more information about the ice and snow melting function of the GX™ 850, please refer to: Appendix B: “How it works”. At least 1 roof sensor is needed for each roof area, but for complex roof constructions, 2 or more sensors are recommended.
28 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 roof. Measuring temperature The heating function is suspended every third hour meaning that the heating cables are turned off. This is done in order to allow the sensors to measure the temperature, without being influenced by the heated cables. The temperature measurement may last up to 20 minutes.

Installer menu Changing parameters and performance of systems System and sensor name It is possible to change the names of the system and connected sensors (see capital A: Installer menu. Clogged drain It is possible to enable and disable the “Clogged drain warning”. The factory setting is “Warning On”. Priority When using the GX™ 850 as a dual or combi system, it is possible to prioritize the systems. When the priority of 2 systems is equal, both systems can heat at the same time.

A typical ice and snow melting system consists of: • GX™ 850 • Only 1 GX™ 850 is allowed on the Devibus™ • Power supply • More power supplies can be connected in parallel (if needed) • Be aware of maximum number of sensors on each power supply (Refer to Technical Specification for power demand of sensors) • Ground and/or roof sensor(s) • Be aware of maximum number and cable length of sensors on each power supply (Refer to sensor manual for a more detailed description) Zone A is used for single system.
