CleaverBrooks CFC-1000 User Manual

CB FALCON
750-265 96
LL - Slave write This allows the slave to accept command messages from a master. 76
Manual firing rate This parameter specifies the analog output or fan speed during burner modulation, when
the Firing rate control parameter specifies Manual mode.
51
MFEP This parameter provides choices for the duration of the MFEP (main flame establishing
period) time. Flame must remain on throughout the MFEP or a response occurs. Not
needed and ignored unless the Pilot type is Interrupted.
60
MFEP flame failure
response
If flame fails in the Main Flame Establishing Period and recycle is selected then the burner
control recycles back to the beginning of Prepurge, then continues with the normal burner
startup process to attempt to light the burner again.
60
Minimum
modulation rate
Provides the lower limit of analog output or fan speed during modulation (this is for both CH
and DHW).
51
Modulation output This parameter selects the modulation output. The Falcon software responds by driving the
appropriate circuit to provide modulation of firing rate.
51
Modulation rate
source
If the modulation rate source is Local, then the control’s PID algorithm determines the
modulation rate.
If the modulation rate source is S2 4-20mA, then the modulation rate is determined by the
S2 4-20mA modulation routine that exists in prior controls. If this sensor is invalid then the
control behaves as if Local were selected.
26
Modulation sensor The selected input provides the temperature clearance for modulation control.
As a startup check, if the CH Loop is enabled for a hydronic system, and if the select sensor
is not a temperature input, then this causes an alert and forces the CH loop to suspend.
26
NTC sensor type The sensors used may all be the 10K NTC type in which safety sensors are redundant, or
all be a 12K NTC type in which no sensors are redundant and external temperature limit
devices are required. The latter is for MCBA retrofit compatibility.
57
OEM identification The OEM may provide identification information here. 21
Outdoor Connector
Type
Designates the Sensor type connected to the control for proper reading. 20
Outdoor frost
protection setpoint
This parameter provides the setpoint for frost protection based on outdoor temperature.
When the outdoor temperature falls below this threshold then frost protection will be active.
Outlet Connector
Type
Designates the Sensor type connected to the control for proper reading. 20
Outlet high limit
enable
Used to set the Outlet high limit on or off. 46
Outlet high limit
response
If Recycle && hold is selected, the burner control recycles and waits for the outlet
temperature to fall. It will remain in this holding condition until the outlet temperature is lower
than the outlet high limit temperature minus 5 degrees F.
46
Outlet high limit
setpoint
If the outlet temperature reaches the value given by this parameter, a response will occur. 46
Outlet T-Rise enable This enables/disables temperature rise detection for the outlet sensor S3 (J8 terminal 8). 44
PFEP This parameter provides choices for the duration of the pilot flame establishing period.
Flame must be on at the end of this period. This parameter is ignored if DBI (Direct Burner
Ignition) is selected.
59
PII enable This parameter enables the Pre-Ignition Interlock input. If disabled the PII input is ignored. 57
PII long name The long name (up to 20 characters) of the PII annunciator input. 61
PII short name The short (3 letter) name of the contacts monitored by the PII annunciator input. 61
Pilot test hold If the Pilot type is Interrupted or Intermittent and this parameter is enabled then the burner
control sequence will hold (forever) at 1 second into the Ignition state, while monitoring the
flame via a 15 second timer.
57
Pilot type Interrupted pilot turns off after MFEP (main flame establishing period). Intermittent pilot
remains on during the Run period (no MFEP). DBI (direct bu
rner ignition) indicates the main
flame is lit directly using a 4 second ignition period.
58
Plate preheat delay
after tap
Whenever the Preheat block is false, it monitors the Tap demand block's output and
operates a timer that ensures preheat will not begin too soon after a tap demand has
recently ended.
