SCHEMAT INSTALACJI

To ensure effective operation of the solar heating system, it is necessary to select proper installation scheme (SERVICE
MENU > INSTALLATION SCHEME) and configure additional options for the selected scheme.
NOTE
While selecting an installation scheme, in the place of the sensor temperature the screen displays the sensor
number. Follow these numbers while connecting the sensors in proper places (order from left to right):
(1) – collector sensor (PT1000),
(2) – tank sensor (PT1000),
(3)– additional sensor 1 (PT1000),
(4) – additional sensor 2 (PT1000).
