FOR THE INSTALLER
Connecting the heat pump to the power supply
Connecting the general alarm, external
input and load monitor
General alarm
The general alarm is activated irrespective of which alarm has tripped.
When a common alarm is required on the heat pump, it is connected
according to the diagram opposite. The contact for the general alarm
output is potential free (no current) and it closes at a general alarm.
Connect max 24 V and 100 mA on the contact.
External input
The heat pump includes prepared functions to permit the heating to be
controlled externally, for example, from a telephone. The input to the heat
pump can be programmed for different functions on the control unit. These
functions are available from menu 1.13 (Remote control heat) and menu 5.7
(Select external controls).
The input must be short circuited to activate the function. Note that the
contact must be potential free.
Load monitor
The load monitor has the task of disconnecting the additional heat in the
event of a too high load on the house’s main fuse. Connect the load monitor
to the external output according to the heading External input above.
Select function 3 in the menu display 5.7 (Select external controls). When
the external input has been short circuited the additional heat is discon-
nected. The heat pump is not affected.
Note: It is not possible to utilise the other functions in menus 1.13 and 5.7 if
you connect a load monitor.
