Every parameter line shows the actual value /attribute for
each parameter.
Select the type of cable used in your installation
(HWAT-R2).
Set the pipe diameter. You can change the value from 1/2"
(DN 15) up to 4" (DN 100)
Set the insulation thickness. You can change the value from
0,35" to 5,30" ( 9mm to 130 mm) with the pipe diameter as
the limiting value.
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-GF 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.
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.
You can determine the high temperature limit.
If this value is reached the unit will switch off
the heating system to avoid scalding.
