Frequently Asked Questions
What types of protocols can this controller integrate with?
It integrates using BACnet, Modbus, LonWorks, N2, or standard Carrier communicating and thermistor sensors.
How is the unit protected from electrical issues?
Incoming power and network connections are protected by self-resetting internal solidstate polyswitches, and the ports are protected against voltage transient and surge events.
What are the operating temperature limits?
The operational range is 0 to 140°F (-18 to 54°C) at a relative humidity of 10–90%, non-condensing.
How many fan coils can one sensor controller manage?
A single sensor controller allows up to eight (8) fan coils to operate from just one sensor.
