User Manual
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 affect the performance of the
roof and ground system, please refer to Appendix B: “How it works” .
Only change the EFIT™ 850 parameters if you are aware of the effects of
your actions .
Reference: Appendix A: Installer menu
Roof system
Melting temperature
Changing the melting temperature will affect when the system is activated in case of
moisture and low temperatures .
The factory setting is 1.5°C.
This means that the heating system will be activated if the temperature falls below
1 .5°C and moisture is detected .
Moisture level
The “moisture level” decides when the system detects moist .
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 appendix A: Installer menu .
The factory setting is 1 hour (on a scale from 0 to 9 hours)
Priority
When using the EFIT™ 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 differs, 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 appendix
A: Installer menu .
