Mk8 MM Manual Page | 65
Par.# Default Range Description
MM: Assured Low Fire Shut Off
If enabled, when the burner turns off on internal stat, the MM will modulate
to low fire, shut down and recycle the system before turning off. Assured
low fire shut off cannot be used with graceful shutdown in parameter 99.
This allows the sequence order to be changed remotely through the DTI or
Modbus. See option 16 and expansion option 100.
MM: Air Pressure Warning Lower Offset
This is an offset lower limit from the commissioned air pressure.
MM: Air Pressure Warning Upper Offset
This is an offset upper limit from the commissioned air pressure.
MM: Gas Pressure Warning Lower Offset
This is an offset lower limit from the commissioned gas pressure, see
parameter 41 for the gas pressure
display units. These limits are also
tested during main flame proving. See option/parameter 125, 126, 127,
128 to enable the pressure limits. A warning will be generated if the
measured static line pressure during the VPS void to gas phase is below
the absolute value in option 133.
0 mbar (disabled) – 1340 mbar
0 inWG (disabled) – 537.777 inWG
0 PSI (disabled) – 19.435 PSI
MM: Gas Pressure Warning Upper Offset
This is an offset upper limit from the commissioned gas pressure, see
parameter 41
for the gas pressure display units. These limits are also
tested during main flame proving. See option/parameter 125, 126
, 127,
128 to enable the pressure limits.
