For Natural Gas :
Input (MBH) =
3600 x cu ft
seconds
Meter = 2 cu ft
Measured time = 72 seconds
=
3600 x 2 cu ft
= 100 MBH
72 seconds
For Propane (LP):
Input (MBH) =
9160 x cu ft
seconds
For Metric formulas- See Glossary
2.
Compare measured input to table below. If calculated
again after setting the combustion following steps in
section 9.12.

P07
00..02 = No function is associated
03 = This is an input contact for CH request (e.g. trigger phone).
When contact CN2 is closed and Room Thermostat (RT) requiring heat switches burner on.
Note: verify heating mode is enabled (winter or heat only mode)
04
E178 anomaly.
Note: verify heating mode is enabled (winter or heat only mode)
05
period.
To enable input it is necessary to set parameter P04 or P05 = 08 and P69 = 05.
Pump will run at P19 minutes (Summer/Winter mode or Only Winter mode) or P19/2 minutes (only Summer mode).
