SETTINGS – REVERSING VALVE
16
DEFINITION DEPENDENCIES FUNCTION
Pressing the Reversing Valve field in the
“System Settings Screen” will invoke the
“Reversing Valve Screen” which enables the
reversing valve output (O/B) to either be
activated for heat pump heating or heat
pump cooling demand.
This functionality is
only used in
operational logic if a
Heat-Pump is chosen
as the Outdoor
Equipment Type.
This functionality defines whether the ON state of
the reversing valve is used for Heating or Cooling.
When the ON state of the reversing valve is used
for Cooling, the signal is typically referred to as a
“O” demand. When the ON state of the reversing
valve is used for Heating, the signal is typically
referred to as a “B” demand.
