Commissioning

If the selected outflow temperature is not reached when the tap is fully 

opened,  then the  water  flow  through  the  device  exceeds  the capacity 

of the device (Thermoflow

TM

 Elex 8.5/12/15/18/21/24).  In this case, the 

flow should be reduced with the hot water valve. There is a danger of 

scalding at outflow temperatures exceeding 108°F.    

Operation

The integrated flow control valve accommodates changes in water 

pressure and thus maintains a fairly constant temperature.

This unit is intended for use with shower heads with a low pressure loss. 

Mixer taps and thermostatic mixer taps should be of a design compati-

ble with devices with flow control. 

Fittings for vented systems should not be used! 

Suggestion: To ensure that the minimum flow (switch-on flow) of a water-

pressure operated device is reached, the pressure loss (head loss) of the 

device,  fittings,  shower  head,  shower  hose  and  piping should  all  be 

considered when installing the device. 

Typical pressure losses at a water flow of approx. 2.6 GPM:

•    Mixer tap: 5.8 - 11.6 PSI

•    Thermostatic mixer tap: 4.4 - 7.3 PSI

•    Shower head: 4.4 - 21.8 PSI

The electronically regulated continuous-flow water heater with automat-

ic  temperature  adjustment  keeps  the  outflow  temperature  constant. 

This  takes  place regardless of the feed temperature, up to the 

temperature limit. 

   

The device has push-buttons to switch it on and off, and arrow keys to 

adjust the heat ing. Blue: decrease heating performance, red: increase 

heating performance. 

Adjust the temperature settings as desired.
