Water
DHW tank top temperature
Current temperature of the DHW tank. If the time window
for DHW tank loading is reached and the temperature falls
below the value set under parameter “
Reload if DHW
tank temperature is below
“, the DHW tank will be
loaded. The DHW tank is loaded either until the time
window has elapsed or the temperature set under
“
Desired DHW tank temperature
“ has been reached.
DHW tank bottom temperature
Prerequisite: Solar panel system is regulated by Froling!
Current temperature in the area of the reference sensor of
the solar panel system.
DHW tank pump control
Specifies the speed of the DHW tank pump as a
percentage of maximum speed.
4.2.2 Water - Temperatures
System menu
Water
Set DHW temperature
When this DHW temperature is reached, DHW tank
loading is stopped.
Reload if DHW tank temperature is below
If the DHW tank temperature falls below the value set
here, the time window is active and the loading source
(boiler or buffer tank) indicates the set loading increase,
and the DHW tank loading is started.
Load if temperature difference between storage tank and
DHW tank is
If the top storage tank temperature is above the current
DHW tank temperature by this value and the time window
is active, DHW tank loading starts (only for systems with a
storage tank).
Load if temperature difference between boiler and DHW
tank is
If the boiler temperature is above the current DHW tank
temperature by this value and the time window is active,
DHW tank loading starts (only for systems without a
storage tank).
Setpoint for temperature difference between boiler and
DHW tank
Adjust the boiler temperature setpoint to reach the desired
DHW tank temperature.
Boiler temperature setpoint = Set DHW tempe
difference
If the current boiler temperature setpoint calculated is
higher than the result from the above calculation, the boiler
temperature setpoint is maintained (only for systems
without storage tank).
