SR868C9Q — this is a controller for Altek, Atmosfera solar water heating systems. Designed to regulate and control the operation of the circulation pump, it is guided by data obtained from temperature sensors installed on the pipe exiting the solar collector and at the inlet and outlet of the storage tank. The safety and efficient performance of the overall water preparation system largely depends on the controller’s operation, so selecting it correctly is very important.

Main advantages of this type of controllers:

controls pump operation based on received temperature values;
use with any types of heat transfer fluids;
"output day" function;
error messages;
protection against incorrect wiring;
password setting;
reset to factory settings
