Highcross ECM-UTM4D Quick Reference Manual

The Highcross ECM-UTM4D is an electronic universal 3-channel
thermostat module designed to control of heating or cooling sys-
tems.
The module has three built-in thermostats, three power relays,
four analog inputs for temperature sensors, three pairs of digital
inputs for priority dry-contact control from window-contact or etc.
