The SUNNYHEAT Interface BL24 can do two things:

  • The setpoint temperature can be controlled via a bus system (e.g. KNX)
  • The lighting can be switched on and off via a push-button

Both functions can be very practical. If the building already has a bus or Smart Home system, SUNNYHEAT integrates itself into it. The setpoint temperature can be changed by means of a bus module. Controlling the lighting not only via ECOcontrol but also via a push button has the advantage that the push button fits seamlessly into the switch programme and the lighting can be operated in the usual way.

Right in the middle instead of just being there

The SUNNYHEAT Interface BL24 integrates SUNNYHEAT into your existing Smart Home System. This requires a bus module that supplies 0 - 10 volts for the setpoint temperature. The setpoint temperature is then transmitted to the SUNNYHEAT system with the SUNNYHEAT BL24 Interface.


Light on

A SUNNYHEAT with lighting can be operated via ECOcontrol or a smartphone. If you also want to operate the lighting as usual via a light switch, you can use the SUNNYHEAT Interface BL24. A 24 V connection is required.

Everything listens to my command

SUNNYHEAT can be expanded from an infrared heater with a thermostat to a small smart home system. With the appropriate software, everything is then controlled from a central location or operated with Alexa.
