Connect a network-connected cable (straight, Cat.5e
UTP) with RJ45 contact (male) to switch AA4-X9 on the
display unit (as illustrated).

AA4-X9
External connection options
GreenMaster-HP has software-controlled AUX inputs
and outputs for connecting the external switch function
(contact has to be potential-free) or sensor.
Go into menu 5.4 "soft in/outputs" on the display to se-
lect to which AUX connection each function connects.

For certain functions, accessories may be required.
TIP
Some of the following functions can also be
activated and scheduled via menu settings.
Selectable inputs
Selectable inputs on the input board (AA3) for these
functions are:
AA3-X6:9-10
AUX1
AA3-X6:11-12
AUX2
AA3-X6:13-14
AUX3
AA3-X6:15-16
AUX4
AA3-X6:17-18
AUX5
The example above uses the inputs AUX1 (X6:9-10) and AUX2
(X6:11-12) on the input board (AA3).
Selectable output
A selectable output is AA3-X7.
The output is a potential-free switching relay.
The picture shows the relay in the alarm position.
When switch (SF1) is in the " " or "
" position the relay
is in the alarm position.
Caution
The relay outputs 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 selections for AUX inputs
Temperature sensor
Temperature sensor can be connected to GreenMaster-
HP.
Available options are:
■
cooling/heating (BT74), determines when it is time to
switch between cooling and heating mode (can be
selected when the cooling function is activated in
menu 5.2.4).
■
hot water top (BT7) (shows the water temperature at
the top of the tank. The temperature sensor is placed
in the submerged tube on the water heater.)
■
external supply line (BT25) (control of temperature to
the heating system)
Monitor
Available options are:
■
alarm from external units. The alarm is connected to
the control, which means that the malfunction is
presented as an information message in the display.
Potential-free signal of type NO or NC.
■
level (accessory NV10)/, pressure/flow monitor for the
brine (NC).
■
pressure switch for climate system (NC).
External activation of functions
An external switch function can be connected to
GreenMaster-HP to activate various functions. The
function is activated during the time the switch is closed.
Possible functions that can be activated:
■
forced control of brine pump
■
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)
