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.
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 15 GATEWAYS. This net communicates with a BMS system through MODBUS protocol.
The interface can:
- Select between OFF/STAND-BY/COOL/HEAT.
- Modify the cooling and heating set point.
- Read the alarm status.
- Read all the functioning temperatures.
- Read the status of inputs (pressure switches, fluid switch, thermal protection...).
- Read the status of outputs (compressor, fan, pump...).
- Read the maximum and minimum set point available in cooling and heating mode.
Parameters:
®
H26 Serial output configuration 1= ModBus.
H44 Family serial address= 0.
H45 Device serial address= 1..8 (different for each one connected to the GATEWAY).
®
H48 Serial output configuration 1= ModBus.
H65 Family serial address= 0.
H66 Device serial address= 1..8 (different for each one connected to the GATEWAY).

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.
