D. INSTALLER MENU
1. Menu Overview
The installer menu allows installing or service
contractors to view and/or make adjustments to the
permanent boiler settings based on the installation
configuration, desired operation and local codes. The
menu structure is shown in Figure 8.13.
To access the installer menu, press and hold the
“Menu” and “Select” key on the LCD display
corresponding to the burner on which the parameter
change is to be made.
a. Managing Burner (Burner M): The top burner on
each PFC-850, PFC-1000 or PFC-1500 boiler is
designated as “Burner M” or “managing burner”.
This burner control is connected to the GEN
(Boiler) circulator, the CH and/or DHW circulator*
and all external sensors*. In the following section,
all parameters which affect only the managing
burner will be designated with “(M)”.
* Stand-Alone configuration or Master Boiler
in multiple boiler configuration.
b. Dependent Burner (Burner D): The bottom burner
on each boiler is designated as the “Burner D” or
“dependent” burner. This burner control is started
and stopped by the managing burner only. Its
operation is not affected by external inputs.
2. Status
The status menu is designed to monitor key
parameters and aids the installer or service contractor
in determining if there are problems with boiler
operation.
a. Current Supply Setpoint: The setpoint value
will change for DHW demands or CH demands
depending on the setpoint chosen for these modes
of operation. When outdoor reset modes are
selected, this value is the calculated target for the
system.
b. Fan Speeds: Screens #2 & #3 display fan speed
information. The current fan speed will vary
during operation between the low power and
high power values. The Low Power, Ignition,
and Hi Power values are preset at the factory for
a specific model size. Table 12.3, in Section 12
of this manual, shows the fan speed presets for
each model size. Note that these values may vary
slightly due to air setting changes.
c. Flame Measurements: Screens #4, #5 & #6
display flame signal information. The first value,
Flame Signal, is the current flame rectification
signal in micro amps (µA). The minimum value
for this signal that will allow the burner to continue
running is 2.8 µA the maximum value for this is 10
µA.
