Operation Instructions
Changing parameters and performance of systems Several parameters for each system can be changed during and after the installation. For a complete understanding of how these parameters aff ect the performance of the roof and ground system, please refer to Appendix B: “How it works”. Only change the GX™ 850 parameters if you are aware of the eff ects of
your actions. Reference: Appendix A: Installer menu
Roof system Melting temperature Changing the melting temperature will aff ect when the system is activated in case of moisture and low temperatures. The factory setting is 35 °F (1.5°C). This means that the heating system will be activated if the temperature falls below 29 ° F (1.5°C) and moisture is detected. Moisture level The “moisture level” decides when the system detects moisture. The factory setting is 50 (on a scale from 5 to 95). The lower the setting, the more sensitive the system is to moisture. Post-heat Once the sensor has detected that the roof/gutter is dry and free of ice and snow the system will keep heating for another hour (default). If you wish to increase/decrease this time see capital A: Installer menu. The factory setting is 1 hour (on a scale from 0 to 9 hours) Priority When using the GX™ 850 as a dual or combi system, it is possible to prioritize the sys- tems. When the priority of 2 systems is equal, both systems can heat at the same time. If the priority of the 2 systems diff ers, and both systems want to heat, only the system with the highest priority is allowed to heat. The factory setting is 1 (highest priority) for all systems. Clogged drain It is possible to enable and disable the “Clogged drain warning”. The factory setting is “Warning On”. System and sensor name It is possible to change the names of the system and connected sensors (see capital A: Installer menu.
