In case of Water pressure switch: "00" means open, "20" means closed.
In case of sensors in short circuit or open circuit, the display visualizes: "--".
Actual Blower Speed is showed always in terms of Hz.
Actual water flow rate is showed always in terms of real l/min *10 and it has to be visualized also with the input switch
contact open. Example: real 1.5 l/min has to be visualized as 15.
Actual Flame Current is showed always in terms of real uA*10. Example: real 0.3 uA*10 has to be visualized as 3.
In case of DHW thermostat, t04: "On" means closed, "OFF" means open.
By pressing the RESET push button for 1 second, it is possible to escape from the "Inquiry" mode. By pressing the RESET push
button for 20 seconds, it is possible to leave the Installer mode. If no action has been taken, the MMI automatically leaves this
mode after 15 minutes.
