Wiring the HVAC Interface Module
Ensure power to connecting equipment is off. To prevent the risk of personal
injury and/or death, make sure power is not applied to the thermostat or HVAC
Interface Module until they are fully installed and ready for configuration. All
work must be done with power to the circuit being worked on turned off.
The HVAC Interface Module includes three
relay power jumper connectors. These are
used to provide power between terminals
when necessary.
• Set Jumper J1 to On to connect power
R to the Rc terminal.
• Set Jumper J2 to On to connect power
R to the Rh2 wiring terminal.
• Set Jumper J3 to On connects power R
to the Rh1 wiring terminal.
• Set the jumper to off to disconnect
the power from Rh1, Rh2, or Rc
respectively.
