Rotate selector to
Eff X-Air
.
The Eff/X-Air screen shows
calculated combustion efficiency
using a Gross Condensing
calculation and excess air .
When below condensing
temperature the efficiency
calculation includes and
estimated energy recovered
during condensation that
increases combustion efficiency .
This calculated value is not
the same as AFUE.
Excess air is a calculated value
representing the amount of
air above the level needed to
completely burn all of the fuel .
NOTE: Negative net temperature
will result in efficiency greater
than 100%
Rotate selector to
CO2 CO
.
The CO2 / CO screen is a
direct display of measured
gases . Carbon dioxide (CO2)
is displayed in percentage
(%), carbon monoxide (CO) is
displayed in parts per million
(ppm) .
These two measurements are
commonly referenced target
values for appliance set up .
Rotate selector to
Temp
.
The temperature screen
will display values for flue
temperature (Tf) and inlet
temperature (Ti) . If inlet
temperature was set during
initial power on, it will
display that temperature . If
using ambient temperature
you will observe the internal
handset temperature .
Note: The sample pump will
stop when CO is less than
40ppm .
Rotate selector to
O2 CO Air
Free
.
The O2/CO Air free screen
shows the calculated amount
of O2 (from CO2 measured
and fuel selected), and CO
Air Free .
CO Air free is a calculated
value for carbon monoxide
as if there were no dilution
from air .
COppm =
[20 .9 / (20 .9 - O2 measured)]
Rotate test selector to
Fuel
.
The fuel selector position will
display the current fuel being
used for calculations .
