In order to reset the heat pump between Master
and Slave 1 – 8, proceed as follows:
1. Check that the heat pump is switched off. Discon-
nect the communication between the heat pumps.
The easiest way to do this is to temporarily discon-
nect the modular cables from the communications
card. (fig. 1)
2. Set the power switch (8) in position “1”.
3. Wait approximately 30 seconds.
4. Turn the selector switch marked U6 (fig. 4) on the
Measure card using a small screwdriver so that the
arrow points to the required position. 0 refers to a
Master while 1 – 8 refers to Slave 1 – 8. Each Slave
is given a unique address for communication with
the Master unit.
5. Wait approximately 5 seconds and check that the
display shows your selection.
Example:
6. Shut down the heat pump by turning the power
switch (8) to “0”. The heat pump is now configured
to act according to the setting.
7. Reconnect the modular cables that were discon-
nected in step 1.

FIGHTER 1330 is always delivered as the Master. Up
to 8 Slaves can be connected to the Master. Only one
heat pump with each address can be installed in the
same system, i. e. only one Master and only one Slave
5.
External temperature sensors and control signals
should only be connected to the Master, with the
exception of the shuttle valve/s (VXV) which can be
connected one on each heat pump. See the section
Description of functions - Start up > Operating type
selection for setting, as well as Description of func-
tions - Basic functions > Hot water production for con-
necting a shuttle valve (VXV).
Should contact between the heat pumps fail, the Mas-
ter will attempt to re-establish communications every
ten minutes. During the period of the communication
error, the text Com. error will be shown as the status of
the heat pump in menu 0.1.x, 5.2.0 and 5.3.0.
When starting a system with several heat pumps,
the Master should never be switched on before the
Slaves. If this does occur, the Master will not the find
the Slaves during start up and the Slaves will then not
work for up to 10 minutes.

Connection of Master/Slave
Daisy-chain the heat pumps by using a screened 3-
core cable. Position A on terminal block X4 Cable on
the communications card (3) should be connected to
position A on terminal block X3 Cable on the commu-
nications card in the next heat pump. In the same way,
position B and GND are connected together with the
communications card in the next heat pump.
