REMOTE SYSTEM WIRING DIAGRAMS
This thermostat has been preprogrammed with energy saving settings recommended under the EPA Energy Star
program. When used with remote systems, HAI recommends that the thermostat be configured as "non-
programmable" (See Setup Item 03 - "Display Options").
HAI AUTOMATION SYSTEMS
The thermostat can be connected to an HAI automation 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 Omni,
Omni II, OmniPro, or OmniPro II controller are connected to Zone 16 and Output 8.
All thermostats on an OmniLT controller are connected to the GRN (Green), BLK (Black), and YEL (Yellow)
terminals in the section marked "TSTAT".
Connect the red COMM cable wire with the black COMM cable wire. Make the connections (as shown in
Figure 7) using the supplied wire splices.
