Safety valve
Safety equipment that must be installed in the cold
water pipe by your heating contractor. The safety valve
opens automatically to prevent excess pressure in the
DHW cylinder.
Solar circuit pump
In conjunction with solar thermal systems.
The solar circuit pump delivers the cooled heat transfer
medium from the indirect coil of the DHW cylinder to
the solar collectors.
Set temperature
Specific temperature that should be reached, e.g. set
DHW temperature for example.
Summer mode
Operating program "Only DHW" .
In warmer months, you can switch off heating mode.
The boiler remains operational for DHW heating. Cen-
tral heating is switched off.
Cylinder loading pump
Circulation pump for heating the potable water inside
the DHW cylinder
Drinking water filter
A device that removes solids from the water. The
drinking water filter is installed in the cold water pipe
upstream of the DHW cylinder or the instantaneous
water heater.
Weather-compensated mode
See "Heating mode"
Time program
In the time programs, you specify what your heating
system should do at what time.
DHW circulation pump
The DHW circulation pump transports the DHW
around a loop line between the DHW cylinder and the
draw-off points (e.g. hot tap). This ensures that hot
water is rapidly available at the draw-off points.
