BC: Terminal T81 Function
For setting 1, terminal 81 acts as an input for a mechanical end stop. It must
be made for the whole of the timed purge and post purge phases otherwise
a lockout is generated. This input must also not be made while not at purge.
For setting 2, terminal 81 acts as purge pressure proving switch input. The
switch must be made continuously for the whole duration of the purge time.
If it drops out, the purge timer restarts once the signal is made again. It
must also not be made before the blower motor starts to confirm the input
is working correctly. If this input comes on during the relay tests a lockout
is generated. Option 158 adds an optional time limit for the purge pressure
proving to be made.

BC: Delay to Purge (T52) Timeout
An input on terminal 52 is required to indicate the system is ready to move
toward the purge phase. If the MM does not see this input for 1 second
within this time set, then a lockout will occur. Setting 0 will disable this
timeout, so the MM would sit indefinitely in delay to purge.

BC: Purge Pressure Proving (T81) Timeout
If option/parameter 155 is set to 2, then the system will lockout if the purge
pressure is not proved within the specified time. Setting to 0 will disable this
timeout, so the MM will be in the purge phase indefinitely waiting for the
pressure proving signal to be received on terminal 81.
