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.
Press “s“ UP or “t“ DOWN
to scroll and press ENTER
“ ” to select desired fuel.
Bottom line displays selected
fuel selected for calculations
Rotate test selector to Date
Time.
Display shows internal clock
and the date.
