Compatibility
Compatible pumps: NIBE S-series
Vadus talks to the pump over Modbus TCP, on the local network.
Requirements and limits
NIBE S-series pumps with Modbus TCP enabled, on the same network as Vadus Air. One system in Vadus is one pump.
The F-series is not supported at the moment. A system cannot contain more than one pump. Vadus does not schedule timetables and does not optimise consumption against a tariff.
Vadus is an independent product, not affiliated with or endorsed by NIBE Energy Systems. The name is used only to indicate compatible equipment.
Settings
14 settings that can be changed
Every value is checked against the setting's limits before it is sent, and confirmed by reading it back from the pump. The right to change is granted separately for each setting.
An expired command is never carried out, and two changes to the same setting are never sent at the same time.
