n Pressure switch minimum (Gps)
The minimum gas pressure switch shuts the boiler down if the inlet
gas pressure becomes too low. The pressure switch must be set at
10 mbar. Connect the minimum gas pressure switch to the Gps
terminals of the connector. Presence of the minimum gas pressure
switch must be activated by means of setting parameter {PSG :} or
p29 (IniControl).
n Gas valve leak proving system (Vps)
The gas leakage control checks and controls the safety valves on the
gas block. The test takes place before the boiler starts up. In the event
of a leak in the gas block, the boiler will lock out. The pressure switch
must be set at 50 % of the admission pressure (Up to 40 mbar).
Connect the gas leakage control to the Vps terminals of the terminal
strip. Presence of the gas leakage control must be specified using
parameter {CCE :} or p33 (IniControl) in settings mode.
