eter to Rooftop.

High BP (High Balance Point)
Default Value: 90°F
In Heating or Auto mode, it is the outside air temperature value at which the auxiliary heat
is cut off. If the temperature exceeds this value, only the heat pump is used to maintain the
heating setpoint.
Function enabled only if outside air temperature value is populated (not -40°F/°C). The Outdoor
Temperature value could be received from a sensor connected directly to the Room Controller
or via a BACnet front end (network).
Range: 34°F to 90°F (1.0°C to 32.0°C)
Low BP (Low Balance Point)
Default Value: -12°F
In Heating, Cooling or Auto mode, it represents the outside air temperature value at which
the heat pump operation will be cut off. If the temperature falls below this value, only the
auxiliary heat is used to maintain the heating setpoint.
Function enabled only if outside air temperature value is populated (not -40°F/°C). The Outdoor
Temperature value could be received from a sensor connected directly to the Controller or via a
BACnet front end (network).
Range: -40°F to +30°F (-40°C to -1.0°C )
