Priority control

When used in conjunction with other electrical equipment, e.g. electric storage heaters, use the maximum
demand relay:
a Maximum demand relay (see "8. Special accessories").
b Control cable to the contactor of the second device (e.g. electric storage heater).
c Control contact, opens when switching the instantaneous water heater on.
The relay trips as soon as the instantaneous water heater starts.
Only connect the automatic maximum demand controller to the central phase of the equipment terminals
(mains power).

Undersink installation, water connections from the top

Undersink installation with water connections from the top can be achieved with the additional pipe assembly
for undersink devices (part no. 18 44 21). Cleanly break out the water pipe knock-outs in the back panel and
fit the pipe set.

Temperature limit

If the maximum temperature is to be limited to 43 °C, this is done on the
inside of the device cap. For this, change the switch from 60 (°C) to 43 (°C).
You can still adjust the temperature selector across its entire range.
The outlet temperature will be permanently limited to 43 °C. A temperature
range between 30 °C to 43 °C can be selected.
