R~Occ Jumper:
Smart Equipment Control boards come from the
factory with a jumper wire between R and OCC
terminals on the thermostat terminal strip. Failure
to remove this jumper will place the unit into the
Occupied mode no matter what the occupancy
demand is from the thermostat or EMS system.
To allow Thermostat or EMS control of the
Occupied mode for the unit, this jumper must be
removed during commissioning.
