ELECTRICAL CONNECTION
NOTE
Read section "Common electrical connection" for
instructions regarding electrical connection.
CONNECTION OF SENSORS AND EXTERNAL
BLOCKING
Brine sensors (EP12-BT57) and (EP12-BT58)
Two sensors (BT57 and BT58) can be connected to display
the temperatures on the groundwater side. An alarm can
be activated in menu 7.2.20 to block the compressor, if the
groundwater out (BT58) from the heat exchanger drops
below the set temperature. Blocking stops automatically,
when the temperature on (BT58) rises by two degrees above
the set temperature. The default setting for the alarm is
deactivated.
Connect the sensor to AA5-X2:17-18.

External blocking
A contact (NO) can be connected to AA5-X2:21-22 to block
the groundwater pump. When the contact closes, the
groundwater pump is blocked.

Caution
The relay outputs on the accessory board can have
a max load of 2 A (230 V) in total.
The auxiliary relay (HR10) is required at a greater
load than 2A (230V).
CONNECTION OF GROUNDWATER PUMP
(EP12-GP3)
Connect the groundwater pump (GP3) to AA5-X9:8 (230 V),
AA5-X9:7 (N) and AA25-X1:3 (PE).
