Product innovation
This solution combines two e-module instantaneous water heaters to supply one or more tapping points with a high hot water requirement (minimum flow rate per individual tapping point: 4 l/min), e.g. a wellness shower. The devices are switched synchronously via the special twin software and temperature settings are automatically adopted by both instantaneous water heaters

The integrated Bluetooth and WLAN function also allows the device to be controlled by remote control or via smartphone or tablet. Using the "Smart Control" app makes it easier to commission and maintain the appliance.

This product is available as a complete set with either a flush-mounted cabinet or a surface-mounted cabinet.

  • Two fully electronically controlled instantaneous water heaters in a special installation frame for flush-mounted installation with Bluetooth remote control
  • For the joint supply of one or more tapping points with a high hot water requirement in order to increase the amount of usable water (e.g. for a wellness shower)
  • The devices are switched synchronously viathe special Twin software, temperature settings are automatically adopted by both devices.
  • Temperature setting, definition of individual temperature profiles and viewing of consumption values via the FX 3 remote control supplied or optionally via smartphone
  • Always accurate to the degree between 20 °C and 60 °C thanks to TWIN TEMPERATURE Control TTC and SERVOTRONIC dynamic flow rate control
  • Blank wire heating system IES ensures a longer service life, less scaling, highly efficient and easy to maintain
  • Electronic safety system with air bubble detection, temperature and pressure cut-out
  • Multiple Power System MPS determines the maximum power consumption during installation: 18, 21, 24 or 27 kW
  • Integrated WLAN and Bluetooth function for connection with smartphone and tablet (from iOS 9 / Android-OS 4.4), this requires the "Smart Control" app
  • Modbus-RTU interface for integration into the building technology
  • Function for thermal treatment at 70 °C for more hygiene
  • Suitable for reheating preheated water (inlet temperature up to 70 °C permitted)
  • Dimensions of the individual device (height × width × depth): 40.2 × 27.8 × 9.9 cm
  • Dimensions of the flush-mounted cabinet (height × width × depth): 72.4 × 74.8 × 15.6 cm

    Also available as a set with surface-mounted cabinet:
    ISX Twin AP, article number 3200-37133, dimensions of the surface-mounted cabinet (H×W×D): 77.2 × 73.1 × 14.0 cm
