REMOTE SYSTEM WIRING DIAGRAMS
This thermostat has been preprogrammed with energy saving program schedules in accordance with the
ENERGY STAR
®
program. When used with a remote system, HAI recommends that the Program Mode be
configured as “None” or “Occupancy”. This will disable the internal program schedules.
HAI HOME CONTROL SYSTEMS
The thermostat can be connected to an HAI Home Control system. The controller can send commands to the
thermostat to change mode, cool setting, heat setting, status of fan and hold, and other items.
Run a 3 (or 4) conductor wire from the HAI system to the thermostat location. All thermostats on an HAI
Home Control system are connected to Ground, Zone +16, and Output 8 - See Figure 11.
