Install Instructions

The GX 850 Dual Zone Automatic Control Panel (ACP) is the most optimal solution for keeping
an area free of ice and snow. The GX 850 ACP is like having a mini weather station monitoring
your installation 24 hours a day. Collecting temperature and relative humidity information from
sensors embedded in the surface material, it is able to accurately sense when to turn the system
on and off. The GX 850 ACP perfectly balances the job of clearing snow and ice while minimizing
energy consumption. By combining moisture and temperature readings, the system is able to
save around 75% energy compared to a system which only measures temperature readings.
The GX 850 ACP has an integral alarm function that monitors the attached sensor and the inbuilt
microprocessor. An external alarm may also be connected to the system. Voltage options include
208V-600V. If software modification is required, the GX 850 Dual Zone ACP software can be
upgraded by using the RS232 data cable.
