HAI THERMOSTATS
OmniLT supports up to 2 HAI RC-Series Communicating Thermostats. 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 OmniLT to the thermostat location. All thermostats are connected to the GRN (Green), BLK
(Black), and YEL (Yellow) terminals in the section marked "TSTAT" on the OmniLT controller. Connect the red COMM cable
wire with the black COMM cable wire. Make the connections (
as shown in Figure 9)
using the supplied wire splices.
