HEATING CABLE & PIPE
Selection of
parameters
Every parameter line shows the actual value /attribute for
each parameter.
HWAT cable
Select the type of cable used in your installation
(HWAT-L, HWAT-M, HWAT-R).
Pipe
diameter
Set the pipe diameter. You can change the value from DN
15 mm up to DN 125 .
Insulation
thickness
Set the insulation thickness. You can change the value
from 9 to 130 mm, with the pipe diameter as the limiting
value.
Boiler sensor
Activate/deactivate a connected boiler sensor by clicking
on ON/OFF. The external temperature sensor measures
the boiler temperature. The trace boiler setting is
included to ensure that the heating cable temperature
does not exceed the boiler temperature. The HWAT-ECO
memorizes the highest measured temperature over
the last 24 hours. If the boiler temperature is too low,
the maximum temperature is lowered to the boiler
temperature minus the trace temperature. In this case
the green trace boiler LED will be on.
Boiler low
temperature
limit
You can determine the low temperature limit. If the
boiler temperature reaches this value, the unit will
switch off the heating system in order to fulfil hygienic
requirements and avoid energy waste.
Boiler high
temperature
limit
You can determine the high temperature limit.
If this value is reached the unit will switch off
the heating system to avoid scalding.
Pipe sensor
Activate/deactivate a connected pipe sensor by pressing
ON/OFF. The pipe sensor monitors the pipe temperature
and needs to be installed close to the furthest point in
the pipe distribution network.
Pipe sensor
low
temperature
limit
You can determine the low temperature limit.
When the value is reached a warning will appear on the
screen but will not interrupt the unit’s functioning. The
info status screen will show the actual pipe temperature.
Pipe sensor
high
temperature
limit
You can determine the high temperature limit. A warning
will appear on the screen when the value is reached but
will not interrupt the unit’s functioning.
