Optional connections
MASTER/SLAVE
Several heat pumps (F1145, F1245 and F1345) can be
connected by selecting one heat pump as master and
the others as slaves.
The heat pump is always delivered as master and up to
till 8 slaves can be connected to it. In systems with
several heat pumps each pump must have a unique
name, that is only one heat pump can be ""Master" and
only one can be for example "Slave 5". Set master/slaves
in menu 5.2.1.
External temperature sensors and control signals must
only be connected to the master, except for external
control of the compressor module.
NOTE
When several heat pumps are connected to-
gether (master/slave), external return sensor
BT71 must be used. If BT71 is not connected,
the product gives a sensor fault.
Connect the communications cables as illustrated in
series to the terminal block X4:15 (A), X4:14 (B) and
X4:13 (GND) on the input card (AA3).
Use cable type LiYY, EKKX or similar.
The example shows the connection of several F1155 .
