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.
