Special start-up procedure (when the system is filled with an antifreeze solution)
A flow rate reading error may occur if you start-up the boiler at low ambient temperature.
This error may occur because the physical properties of antifreeze solution. If the
B indicator flickers and the cut-off valves are opened you have to close NA and RP
contacts which will automatically start the special start-up procedure. As a result, the
medium will be warmed up to temperature that enable you to read the flow rate correctly.
The duration of procedure depends on both the installation capacity and the temperature
inside the installation. When a control panel display (J) shows selected parameters
alternately and marks („-”, „--”) it means that the procedure is started. The procedure
will close automatically and the boiler will start normal operation once the minimal flow
rate is reached.
