- Page 2 2. DESCRIPTION AND CHARACTERISTICS OF THE PRODUCT The heater regulator is used to regulate the load of the panels by changing the PWM filling factor, and in combination with the charge buffer as an active load. This allows the panels to work at the MPPT point, i.e. the largest power factor. The condition for proper operation and the highest energy yields is to ensure the appropriate load for the regulator.
- Page 3 3. INSTALLATION AND CONNECTION The device for proper operation requires proper connection. The final place of installation is the wall inside the building. The regulator should be mounted near the boiler so that there is no need to extend the temperature sensor cable. The recommended connection system of the regulator is below.
- Page 4 4.KONFIGURACJA The configuration consists in setting the set temperature to be reached by utility water. This is done by pressing the MENU button until an intermittent sound from the controller appears. Then the inscription "S.tE" appears on the top display, which means setting the set temperature.
- Page 5 The method of communication is not related to any communication protocol. In order to read the operating parameters, a query should be sent to the regulator in the form of one byte of data. Transmission parameters are: 9600 8n1. Sending one byte to the driver with the following information: ASCII 'a' (97 decimals) results in the answer: AA;...
