Mikrofill Maxi Plus, Technical Documentation Manual

7 Manual override

In the unlikely event of a sensor failure the unit may give incorrect readings and could cause alarm conditions. If this 
occurs, a manual override can be employed by depressing the        and the       service mode buttons simultaneously
for 3 seconds; thus reinstating the BMS relays in the unit. Before operating the manual override you must ensure there 
is sufficient pressure in the system. The manual override must not be employed if the unit has shown a flood 
alarm condition or, if there is insufficient pressure in the system.

8 Audible alarm mute

If the Mikrofill Maxi does indicate a fault, an audible alarm will sound. This can be muted by depressing the 
        service mode button.

9.1 Press and hold the        service mode button for approx 8 seconds
