COOLING MODE
When the outdoor temperature exceeds 35ºC, the
unit set point is the set value. The Dynamic set point
function starts when the temperature is below 35ºC.
The set point value increases below 35ºC, so for
25ºC (10ºC differential) the set point is 3ºC more
than the set value.
BMS CONNECTION
It is possible to connect the unit to a BMS system with a MODBUS protocol.
A communication adaptor is installed in the unit. With a GATEWAY, 8 units can be connected. It is possible to
achieve a net with 16 GATEWAYS. This net communicates with a BMS system through MODBUS protocol.

HEATING MODE (only for heat pump units)
When the outdoor temperature is 6ºC the unit set
point is the set value. The Dynamic set point function
starts when the temperature exceeds 6ºC. The set
point value decreases above 6ºC, so for 12ºC (6ºC
differential) the set point is 4ºC less than the fixed
value.
