selection of Every parameter line shows the actual value /attribute for

Hwat cable select the type of cable used in your installation
(HWAT-l, HWAT-m, HWAT-r).
pipe set the pipe diameter. you can change the value from dn
diameter 15 mm up to dn 125.
insulation set the insulation thickness. you can change the value from
thickness 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 you can determine the low temperature limit. if the boiler
temperature temperature reaches this value, the unit will switch off the
limit heating system in order to fulfil hygienic requirements and
avoid energy waste.
boiler high you can determine the high temperature limit.
temperature if this value is reached the unit will switch off
limit 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 you can determine the low temperature limit.
low When the value is reached a warning will appear on the
temperature screen but will not interrupt the unit's functioning. the info
limit status screen will show the actual pipe temperature.
pipe sensor you can determine the high temperature limit. A warning
high will appear on the screen when the value is reached but
temperature will not interrupt the unit's functioning.
