Connections
NOTE
To prevent interference, unscreened commu-
nication and/or sensor to external connections
cables must not be laid closer than 20 cm to
high voltage cable when cable routing.
Power connection
GreenMaster-HP must be installed with a disconnection
option on the supply cable. Minimum cable area must
be sized according to the fuse rating used. Enclosed cable
for incoming supply electricity is connected to terminal
block X1 on the immersion heater board (AA1). All install-
ations must be carried out in accordance with current
norms and directives.

If a separate supply to the compressor and electric
heater is required, see section "External blocking of
functions" on page 28.
Tariff control
If the voltage to the compressor disappears for some
time, simultaneous blocking of this must take place via
a software-controlled input (AUX input) to prevent an
alarm, see section “External blocking of functions" page
28.
Connecting sensors
Connect the sensor(s) to terminal X6 on input
board(AA3) according to the instructions below.
Outside sensor
Install the outdoor temperature sensor (BT1) in the shade
on a wall facing north or north-west, so it is unaffected
by the morning sun for example.
Connect the sensor to terminal block X6:1 and X6:2 on
the input board (AA3).
If a conduit is used it must be sealed to prevent condens-
ation in the sensor capsule.
