Turn switch from “summer” on “winter” position.
Switch to “off” position for 2 sec., then turn
switch to position “winter”
Only after a delay time of 30 minutes heating
starts
. This delay of time is required for
elimination of possible air bubbles from circuit
and to deaerate/bleed by hand the circuit (pos.12),
the pump (pos.2) and the heating unit (pos.5).
Also the last position of drawing-off of water must
be rinsed well. (Take water off)
Temperature measured by
forward flow lime protection sensor
exceeds 60°C
The
security temperature control
( STB ) triggers.
The
return flow temperature
falls under 3 °C.
Adjustment of
return flow temperature
between 5 °C and 17 °C
LED (Light emitting diode) illuminates once per second.
Function: 24 hour signal
LED circulation pump illuminates, circulation pump runs.
After 10 minutes the pump switches off and the light diode
stops blinking. After a pause of 24 hours, the circulation pump
restarts automatically and the LED illuminates again!
Function : Anti-sticking pump protection
( LED -> Light emitting diode )
LED (Light emitting diode) circulation pump illuminates,
circulation pump runs. The forward flow lime protection
light diode illuminates and is active.
fter a delay time of 30 minutes ->
LED circulation pump illuminates,
circulation pump runs.
A
LED Heatig
illuminates.
Heating starts to warm up water until desired
temperature at return flow temperature sensor
is reached.
Lime protection LED goes off.
Heating LED goes off, water heating stops.
After cooling
under 60°C
heating starts again
automatically.
Heating LED illuminates again.
The LED light of Security Temperature Control
illuminates and a signal tone sounds.
Heating LED goes off, Water heating stops.
The security temperature control limiter (STB) turned off.
Kindly see description of how to activate the STB again!
LED alarm illuminates and a signal tone sounds.
LED Heating illuminates, heating warms up water.
Heating element warms water up until desired
temperature at return flow temperature sensor
is reached.
