Some of the following functions can also be activ-
ated and scheduled via menu settings.
Selectable inputs

tions are:
AA3-X6:9-10
AUX1
AA3-X6:11-12
AUX2
AA3-X6:13-14

AA3-X6
The example above uses the inputs AUX1 (X6:9-10) and AUX2 (X6:11-12) on
the input board (AA3).
Selectable outputs
A selectable output is AA3-X7.
The output is a potential-free switching relay.
When switch (SF1) is in the " " or " " position, the relay is
in the alarm position.

AA3-X7
Caution
The relay output may be subjected to a max load
of 2 A at resistive load (230V AC).
TIP
The AXC accessory is required if more than one
function is to be connected to the AUX output.
Possible selection for AUX inputs
Temperature sensor
Available options are:
•
cooling/heating/hot water, determines when it is time to
switch between cooling, heating and hot water mode
(selectable when the air/water heat pump is permitted to
produce cooling).
•
supply temperature sensor for cooling (BT64) (used when
“active cooling in 4-pipe system” has been activated in
the output AA3-X7)
Monitor
Available options are:
•
alarm from external units.
The alarm is connected to the control, which means that
the malfunction is shown as an information message in
the display. Potential free signal of type NO or NC.
•
stove monitor for accessory ERS.
Stove monitor is a thermostat that is connected to the
chimney. When the negative pressure is too low, the fans
in ERS (NC) are switched off.
•
pressure switch for climate system (NC).
External activation of functions
An external switch function can be connected to VVM 310
to activate various functions. The function is activated
during the time the switch is closed.
Possible functions that can be activated:
•
hot water comfort mode “temporary lux”
•
hot water comfort mode “economy”
•
“external adjustment”
When the switch is closed, the temperature changes in °C
(if the room sensor is connected and activated). If a room
sensor is not connected or not activated, the desired
change of “temperature” (heating curve offset) is set with
the number of steps selected. The value is adjustable
between -10 and +10. External adjustment of climate
systems 2 to 8 requires accessories.
–
climate system 1 to 8
The value for the change is set in menu 1.9.2, "external
adjustment".
•
SG ready
Caution
This function can only be used in mains networks
that support the "SG Ready" standard.
"SG Ready" requires two AUX inputs.
"SG Ready" is a smart form of tariff control, through which
your electricity supplier can affect the indoor, hot water
and/or pool temperatures (if applicable) or simply block
the additional heat and/or compressor in the heat pump
at certain times of the day (can be selected in menu 4.1.5
after the function is activated). Activate the function by
connecting potential-free switch functions to two inputs
selected in menu 5.4 (SG Ready A and SG Ready B).
