Wiring Hvac Equipment - Honeywell Panel EnviraZone W8835 Manual Del Usuario

W8835 ENVIRAZONE PANEL
If the heat pump equipment has an L terminal that is energized
on heat pump failure, connect it to the L equipment terminal
and wire C on the left side of the panel to the HVAC common
terminal. When the L terminal is energized, the thermostats
illuminate the red Em Heat light.
For dual fuel equipment using heat pump and fossil fuel,
configure the panel as a heat pump and use a fossil fuel kit. Do
not use the dual fuel functionality of the VisionPRO® IAQ.
