The KNX-LUNOS-CONTROL4 module enables the control of the decentralised ventilation units with heat recovery Series e2 and ego and the exhaust air fan RA 15-60 via the KNX bus. Up to 4 ventilation units can be operated with one module. Several modules can be networked with each other via the KNX bus to enable coordinated operation. The ventilation units can be directly controlled via the existing push-button inputs.
The module has an integrated KNX bus coupler and requires an additional voltage. It is located in a plastic housing which can be inserted into a standard flush-mounted box. The module can be controlled with the KNX display Touch-IT or directly with a series switch. Automatic control without switch via humidity or CO2 sensor is also possible. The protection class corresponds to IP20.
Power supply of the fans from low voltage 24 .. 32 VDC
Operation of 2 pairs of fans (4 fans) with one module
Several modules cascadable (master/slave operation)
Control of the fan stages and directions as well as heat recovery
Manual setting of fan levels via push-button/switch inputs or KNX telegrams
Automatic filter change indicator upon reaching the change time
Adjustment of fan capacity and heat recovery according to the sizes:
Air humidity relative (indoors) to the moisture removal
Absolute humidity (indoors/outdoors) for cellar drying
Temperature (indoors) for building protection
Temperature (indoors/outdoors) to optimise heat recovery
Temperature (indoors/outdoors/setpoint) for heating/cooling support
