Master/Slave menu
The Master/Slave function is used to manage several units (maximum of 8) supplying air to the same room and providing
automatic weekly rotation (168 hours). This is done to ensure uniform wearing of the AHUs.
A backup/additional function is also available.

Unit(s) on standby : 1 to 7 (according to the total number of units linked and integrated into a rotation loop – 1)
1 rotation per : 0 to 999h (when the value 0 is applied, this allows the rotation to be checked as it will be carried out every 5
minutes)

Managing a network of controllers
The pLAN network is the name of the physical network that links controllers to remote HMI terminals.
pLAN = p ersonal L ocal A rea N etwork
The connection of the controllers via the pLAN network allows the datapoints of one controller to be exchanged for another,
following the logic set out by the program, i.e. the direction that these datapoints must follow and that from which they come. As a
consequence, they are not programmed by the user, who must only carry out the electrical connection.

3.1.1
Connecting controllers to the pLAN
The electrical connection between the controllers under the pLAN network (RS485) is carried out using an AWG20/22 shielded
cable composed of a twisted pair and a shield. The cards must be connected in parallel using the J11 connector.
The first and last controller must be no more than
500m apart.
