Configuration of analogue outputs
See the chapter on Electric Connections for the number and type of analogue outputs used and for information on the
symbols used on labels supplied with the device.
There are 4 analogue outputs. 1 high voltage one and 3 low (SELV) voltage ones, the exact number depending on the following models and
with the following characteristics:

Triac analogue output (TC1)
Available only in models with 4 relays
High voltage output generally used to pilot fans or water pumps.
The output can be configured for proportional operation (constant speed variation) or as ON/OFF.
Remote control switches downstream from the Triac are NOT permitted.
The TC1 output can be configured as described in the table “Analogue Output TC1 - AO1 AO2 : configuration table”
Configuration of low voltage (SELV) analogue output
•
AO1 always available
o
If configured as digital, see parameter CF51
•
AO2 see models chapter
o
If configured as digital, see parameter CF52
They can be configured as:
o
PWM (via CFS modules) or
o
open collector (On/Off).
•
AO3 - low voltage (SELV) output to pilot external modules to run fans
Can be used to pilot 4-20mA fans or 0-10V fans (via parameter CF30)
To configure, see the table below. All analogue outputs can be configured as digital or proportional.
