- Page 2 Technical specifications..........................Application The digital solar thermal controller ZPR-D is a universally applicable and robust device for the temperature difference control for the area of the solar thermal systems, heating systems and air conditioning systems. The device distinguishes itself by special economic efficiency and is held consciously extremely easy in service and assembly.
- Page 3 KT-Elektronik ZPR-D Function The digital solar thermal controller ZPR-D has two rotary switches serveable on the front. With the rotary switches are given the threshold ∆T and according to operating purpose a Maximum or Set/pont of temperature (T The device continuously mieasures two connected temperature sensors and determines the temperature difference ∆T .
- Page 4 ZPR-D. IIn the front of the ZPR-D two switch waves of the rotary switch are visible which can be adjust with a slit screwdriver (size 4 mm) in the position which corresponds to the desired scale value.
- Page 5 KT-Elektronik ZPR-D System variants System variant 1: Solar thermal system The program controls the solar circuit pump depending on the temperature of the solar collector and the storage tank temperature. If the temperature in the solar collector is higher than the buffer temperature, the solar circuit pump is turned on.
