B. 1. For Scholar V heat pump or air conditioner that interfaces with a building
automation system (BAS) or energy management system (EMS), detailed
instructions for the specific system being installed will be supplied separately by
the manufacturer of the BAS/EMS system.
The control of the GreenWheel
®
ERV or Ventilation relay (VR) and the
energy management relay (EMS) are 24 volt inputs to the PLC. If 120 V. of
240 inputs are required, additional relays must be installed in the factory or
in the field.
2. For models with an internal thermostat, no internal control wiring is required. The
thermostat is preprogrammed at the factory to maintain a heating mode
