Remote sensors
Remote mount temperature sensors use 10K type 2 NTC thermistors. See Remote Inputs wiring diagram below for
wiring information.
• Each sensor can be configured for various averaging combinations
• Optional occupancy led
• Optional override key
• Remote mount temperature sensors use 10K type 2 NTC thermistors.
