domat FC013 Protocol Manual

FC013 – EC (0...10 V) fan controller (with UC013), RTC, 2xDO, 3xAO 0-
10 V, 2xDI, 2xRS485
- 50 words can be read at the same time (i.e. 100 bytes)
- whole range can be addressed bitwise
- the whole memory is mirrored as read-only from address 0x101 (e.g. 257 dec)

type description
R module type identification
R firmware version
R, W RAM module status lower byte
bit 0 – write to EEPROM enabled
bit 1 – SW reset enabled
bit 4 – init EEPROM
R, RAM module status upper byte
bit 0
bit 1
bit 2 – 1 – EEPROM initialized
bit 3 – N/A
bit 4 – 0
bit 5 – SW reset enabled
bit 6 – 0
bit 7 – commissioning mode (1 –
R,W Modbus module address
EEPROM (default = 1)
(0x01) To distribute load, fans and
outputs are enabled after address
modulo 10 secs
0 normal mode
1 init mode
1 at the next EEPROM
write attempt will all data
be written to EEPROM,
0 at the next EEPROM
write attempt will received
data be written to RAM

Init EEPROM follows if
the INIT switch was ON at
power up, and if INIT
switch was OFF at setting
bit 4 to 1 (indicated by bit
2 in Status MSB)
SW reset follows if
enabled and 1 is written
into the SW reset register
(address 1002)
!!! the change will be
effective after restart only
(however the register will
be set immediately)
