System overview
The GX-850M ver. IV can handle up to 2 independent areas, in any of the following combinations:
•
Single roof system
(1 system, 1-4 roof sensors)
•
Single ground system
(1 system, 1-4 roof sensors)
•
1 ground system and 1 roof system (combi system)
(2 systems, 2-4 sensors total, minimum 1 sensor per system)
•
2 roof systems (dual system)
(2 systems, 2-4 sensors total, minimum 1 sensor per system)
•
2 ground systems (dual system)
(2 systems, 2-4 sensors total, minimum 1 sensor per system)
When more than 1 area is controlled by the GX-850M ver. IV 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 pre-
sent.
A typical ice and snow melting system consists of:
•
