Live Operating description
5
When the temperature in the collectors reaches the maximum value (adjustment parameter
CMAX
, factory setting 110°C),
the solar pump is triggered to cool the collectors.
The pump continues to operate until the temperature in the collectors is lower than 5 K at parameter
CMAX
and/or the
maximum storage temperature (80°C) is reached in the hot water storage tank.
6
When there is less available sunlight, the temperature in the collectors drops and the temperature in the DHW tank is
stable.
7
As soon as the temperature in the collectors drops below the temperature in the calorifier, the calorifier is cooled down to
its set temperature.
8
When the set point
SX
is reached, the circulation pump shuts down, the temperature in the collectors drops again and the
temperature in the DHW tank falls according to any draw-offs made.
The DHW tank cooling function is inactive if using tubular
collectors (function
FT
active).
3.4.2. Protection against overheating on the solar
circuit
The control system has various functions, which are easy to discern
for the user, which limit overheating of the installation’s components.
