10.9 Work in series function

10.9.1 Work in series logic

1) When several machines work in series, one machine works as master, the others work as slave
a. The slave machine operates according to instructions of heating requirement from master machine.
b. Machines stop working when water temperature reaches the setting value of master machine.
c. Slave machine operate according to water temperature setting value of master machine and provide heating.
It stops or protects according to failure in itself.
2) Quantity of machines in series: Maximum 7 machines work in series, which can be of same or different capacity.
a. Machines start working from machine 1 to machine 7 in turn.
b. Machines stop working from machine 7 to machine 1 in turn.
3) It can display master or slave on current control panel of each machine. When machines work in series,
the bigger capacity machine is as master.
4) All inputs and outputs are handled only by the terminal block of the master machine.

10.9.2 Work in series connection

1. Take the remote controller wire (of all machines) out from port CN16 on PCB. Connect signal wire to CN16.
2. Use signal wire to connect every PCB CN16 to A-Serie board from master #1 to slave #N (N=total heat pump
quantity in the cascade). Connect the remote controller to RC in A-Serie board.
3. Set address by Dip-Switch as following form in every unit:
Dip switch
#1(master)
1 ON
2 OFF
3 OFF
4 OFF
4. After wiring connection, set the quantity of machines work in series by controller. In main menu, press
