5.3 Limiting the range of temperature settings
The turning range of the temperature selector can be
limited to prevent energy-saving setting “E” (approx.
60 °C) or the “Warm” setting (approx. 40 °C) being
exceeded.
The temperature-setting range must only be adjusted
by a qualified service installer, proceeding as follows:
● Pull the temperature selector knob (1) off.
● Pull the limiting ring (b) off the head of the
temperature selector knob (
1).
● Rotate the limiting ring (b) and align it with the
groove (d) that corresponds to a temperature-setting
limit of 40 °C or the groove (
e) for 60 °C. Push the
ring into the groove and onto the plate (
a) of the
temperature selector (
1).
● Push the temperature selector knob (1) and limiting
ring (
b) back into position, while ensuring that the
limiting plate (
f) lies inside the recess (g) in the
regulator spindle (
c).

5.4 Taking the system out of service
If the VEN electric storage water heater is to remain out
of service – in an unheated room – for an extended
period, it can be drained of water. Do not forget to
unplug the unit from the mains power supply before
draining it.
