only)
1.
Install the DHW tank temperature
sensor.
See Installation
Instructions for domestic
hot water tank.
Please note:
When installing the sensor in DHW
tanks of other makes, make sure
that the sensor is pressed against
the sensor well of the DHW tank
by means of a suitable device.
2.
Ensure that the
maximum
permissible domestic hot water
temperature is not exceeded. If
necessary, install a suitable safety
device for this purpose.
