a
All temperature registers are expressed in ×C regardless what Temperature units (register 179) is set to. Temperature range is -
40×C to 130×C with values given in 0.1×C units (for example, 32.0×C = 320). A temperature that is NOT applicable in this
Falcon, i.e., not enabled, has a value of 0x8FFF. This temperature setting is denoted as "UNCONFIGURED" at the user
interface.
b
All percentage values are given in 0.1% granularity, i.e., 0-1000 is the range for 0.0-100.0%.
c Most significant bit in value determines which units type the parameter has: 0=RPM, 1=%. If Modulation Output parameter (reg-
ister 192) doesn't match with the setting of this bit, then the parameter setting is invalid.
d
All temperature registers are expressed in ×C regardless what Temperature units (register 179) is set to. Temperature range is -
40×C to 130×C with values given in 0.1×C units (for example, 32.0×C = 320). A temperature that is NOT applicable in this
Falcon, i.e., not enabled, has a value of 0x8FFF. This temperature setting is denoted as "UNCONFIGURED" at the user
interface. When
configured for raw a2d counts a range of 0-4095 counts is outputted with no error detection provided in the corresponding status
register. When configured for 0-15 psi or 0-150 psi the value is expressed in 0.1 psi precision.
e
Pump control changed in Falcon starting with application build 1600 (see register 189). Pump status changed as a result.
Table 12 contains the status values for units prior to build 1600, and table 13 for build 1600 or later.
f
This register is a safety configuration parameter that requires successful access login (see register 177) before the setting can
be changed. Changing this parameter also requires a safety verification with the Falcon control afterwards to confirm that its
new setting is consistent with the other safety parameters.
g
Commanded rate in least significant byte of this register can be expressed in two formats: binary fraction % or multiple of 0.5%
steps. Bit 8 of this register indicates which format the commanded rate is expressed in; when bit 8 is set, the commanded rate is
in binary fraction % format and when bit 8 is cleared, the commanded rate is in 0.5% steps.
h
For binary fraction % format commanded rate is a binary fraction between .00000000 (0%=no heat at all) and .11111111 (99.98%
heat = maximum fire). For 0.5% step format commanded rate is a value between 0 (minimum fire) and 200 (maximum fire) that
is a multiple of 0.5% (200 x 0.5% = 100%).
i
For Modbus binary fraction mode the CH Modbus rate (register 581) is a binary fraction between .00000000 (0%=no heat at
all) and .11111111 (99.98% heat = maximum fire). For Modbus modulation step mode the CH Modbus rate is a 0.5% step format
with a value between 0 (minimum fire) and 200 (maximum fire) in multiples of 0.5% (200 x 0.5% = 100%).
