|d5| — Actual temperature from the outdoor sensor |NC|.
|d6| — Actual fan speed multiplied by 10 (Example: If fan speed displayed is |410| RPM x 10 = 4100
actual fan speed)
|d7| — Actual ionization current read from flame rectification probe
|d8| — Actual status of the central heating circulator Off = |0|, On = |1|.
|d9| — Actual status of the indirect fired circulator Off = |0|, On = |1|.
|d10| — Actual status of bus communication |co| = connected, |nc| = not connected
|d11| — Central heating set point
|d12| — Power on hours in thousands (display will not read until 100 hrs.)
|d13| — Total central heat hours in thousands (display will not read until 100 hrs.)

|d15| — Passed ignition attempts in thousands
|d16| — This function only becomes active when heater is set as the Master. It allows the user to monitor
the System Pump connected to the Master Heater (0 = Off, 1 = On) in a multiple heater installation. Each
heater firing output percent is displayed.

NOTE: If you toggle beyond parameters of connected heaters, the display will go into the next function
value.
E. TEST MODE
This function is intended to simplify the gas valve adjustment if needed. Listed below are the
recommended limits on the heater and Combustion Settings. Automatic modulation does not take place
when the controller is in Test mode, only temperature limitation based on the Central Heating set point.
The user may increase or decrease fan speed by pressing either
To activate Test mode, simply press
the display
{Ser}
and the actual fan speed. Measurement of combustion levels should always be taken at
{S2}
and
{S3}
together for 1 second. Once activated, you will see in
{S1}
or {S2}.
