Instructions ECL Comfort 210 / 310, communication description
ECA extension
Serial number, code number, software version and hardware
version can be read for an attached ECA 32 or ECA 33 module.
The formats are just as for the ECL controller.
Code no. type is reserved for future use, currently 0 is always read.
If no ex
tension modules are attached, the PNU will return 0.

implemented.
Read PNU 10213 to check whether an ECA 30/31 unit is attached as
HMI A, or PNU 10216 to check whether an ECA 30/31 unit is
attached as HMI B. If no room unit is attached, the value19200 will
be returned.

Value Command Comment
2 Reset internal ECL log Also reset during application installation
PNU 2097, Wink display back light in seconds. Write 0 to abort
active wink. If an ECA 30/31 is connected to the ECL, the ECA will
also wink.
6.14 Output status, Manual output status and Output
override
When the controller is in Manual mode it controls all output used
by the specific application. The manual control has priority.
When the controller is not in Manual mode, the output can be
controlled by “Output override”.
It is not possible to set the manual output state from the
Modbus interface – it can only be achieved via the ECL display
(or ECA 30/31 remote unit).
6.14.1 Output status (from version 1.10)
PNU 3999 holds a read only bit mask for all ECL outputs.
Bit 15 - 12 Bit 11 Bit 10 Bit 9 Bit 8 Bit 7 Bit 6
Reserved Relay6 Relay5 Relay4 Relay3 Relay2 Relay1
Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

See the application description for determining the usage of each
output.
