. Using the remote control:
- After 30 seconds without use, the terminal will go to standby (display switches off) to save the batteries. To "wake"
the terminal, press any key. The display "----°C" appears on the screen, flashing for a few seconds, while it synchronises with its
receiver.
. Battery change indicator:
- When the terminal has been woken, if "bAt" appears for a few seconds (rather than flashing "----°C") the terminal
batteries must be replaced.
- In the case or "beats" if fixed speed(look), piles cannot assure(insure) any more the food(supply) of the terminal.
Compulsory change of piles.
14 - MASTER/SLAVE FUNCTION
Press the button The display becomes "del"
Deconfiguration is done automatically. The sequence is completed as soon as the display becomes "CF O". From this moment,
the terminal and its receiver are unapplied
In the case or "CF2" appears on the display(posting), it indicates that the désapairage of the terminal was made while the
communication with his(her) receiver was broken.
In this case of figure :
Rest(Support) again on the sideline So as to have the display(posting) " CF 0 " (CF 0 = désapairé terminal).
Désapairer the receiver in a individual way: rest 5s the button Of the receiver. The blue clairvoyant(light) (1 ) quickly flashes.
The receiver is désapairé.
A master can control up to 15 slaves.
Two wires + shielding lead from the master unit to the first slave. Two wires + shielding lead from the first slave to the second
slave, etc.
Wires do not have to lead out from the last slave. The distance between two controllers must not exceed 30 m (see cable
characteristics on p16)
The master communicates the following information to the slaves:
● Setpoints
● Air temperature
● Water temperature
● Current mode
● Manual ventilation speed
● State of inputs D1 and D2.
It is possible (via P11) to set the slave units on the return air sensor (e.g. open plan offices).
A slave must not have a room unit.
The operation resulting from the combination of the Off, Frost protection, Economy, Comfort, Window open states between the
master and the slave is designed to reduce energy consumption to the minimum.
Starting up a Master/Slave unit:
. The Master and Slave units are detected automatically.
→ The master is the unit at the head of the master/slave bus
→ When the loop is powered up, the master automatically detects the slaves connected downstream of it (see
wiring diagram below)
→ Check the number of slaves connected to the Master via diagnostic d00
→ If the number does not match, check the wiring
→ Set any parameters on the Master (new setpoint, etc.); they will automatically transferred to the connected slaves
(see list pp 7 and 8)
→ Set any parameters on the Slaves (control on return sensor, etc.)
Two scenarios:
● If the setting is entered on the first Slave in the loop, all the slaves located below it will have the same settings.
● If only one slave is affected: temporarily disconnect its bus to separate it during the setting procedure.
→ It is possible to transfer all the parameters (see list pp 5 and 6) from a master to all of its slaves (when replacing a
Slave controller): see p55 = 3
→ If the master/slave connection is broken, all the slaves located downstream of the break will switch to "Standalone"
mode and retain their operating status during the break.
→ The master terminal will then display the symbol; the d07 will provide the information on the "loss of
communication with the slaves": d07 = 1.0.0 (see § Diagnostics p9)
