Description
1 solar collector, 1 storage tank, 1 pump and auxiliary heating device
Description
The solar collector’s circulation pump (P1) starts when the specified temperature difference for switch-on
(ΔTon) between the solar collector temperature (T1) and the temperature (T2) in the bottom of the
storage tank is reached. If the difference between the solar collector’s temperature (T1) and temperature
(T2) in the bottom of the storage tank falls below the specified temperature difference for switch-off
(ΔToff), or the temperature (T3) in the upper part of the tank reaches the maximum permitted value, the
circulation pump (P1) switches off.
Auxiliary heating device
(also see section 4.4)
If the temperature (T3) falls below the set switch-on temperature within the period of auxiliary heating, the
circulation pump (H1) starts for the auxiliary heating device. When (T3) has reached the specified switch-
off temperature the circulation pump (H1) switches off.
