EEPROM
controller configuration, part 2
(defaults = fan stage reset enable,
slave off, DI2 as window contact,
correction reset enable, PI control,
logical levels, 4-pipe, 0x89)
bit 0 ... fan stages reset to
Auto when presence
mode changed
bit 1 ... enable FC Slave
function (controller will not
communicate with room
unit)
– change only
applies after restart
bit 2 ... DI2 as alarm
input, switches off all
outputs
bit 3 .. temp correction
reset to 0 when presence
mode changes
bit 4 ... control mode (0
–
PI, 1
– on/off)
bit 5 … reserved
bit 6 … 0: logical DI
levels, 1: physical DI
levels
bit 7 ... fancoil type: 0: 2-
pipe, 1: 4-pipe.
multi-slave
number
29 MSB
R,W
EEPROM
amount of FC013 slaves
(connected to the same bus as
UC013, starting with Modbus
address 10)
– if this value is non-
zero, the controller acts as a
master
!!! the change will be effective after
restart only
(default = 0)
0 ... multi-slave function is
off
1 or above ... number of
FC013 slave modules
manual heat
digital output
30 LSB
R,W,RAM
manual setting of DO1 (only if the
corresponding bit in
manual
control
set, otherwise the output
copies the AO1). In manual mode,
the DO is always a PWM output
regardless of reg. 29 LSB bit 4.
in %, range 0 .. 100%
manual cool
digital output
30 MSB
R,W,RAM
manual setting of DO2 (only if the
corresponding bit in
manual
control
set, otherwise the output
copies the AO2). In manual mode,
the DO is always a PWM output
regardless of reg. 29 LSB bit 4.
in %, range 0 .. 100%
latch enable
31 LSB
R, W RAM
Latch enable function for individual
inputs:
By writing
1
into the register the
particular bit in the
latched value
register goes to 0 and is kept until
the required value is catched.
After reset, the whole register is
set to 0.
Resetting of the individual
catched bits in the
latched
Value register
:
change
the particular bit from log.
0 to log.1 (disable and
enable the latch function
for individual bits)
