Connections

DI1 DI2

DO1 DO2 DO3 DO4 DO5 DO6 DI3
(od) (ALA) (CoP) (dEF) (FAn) (Lgt)
(rHt)

DI1

Digital input signal.
The dened function is active when the input is short-circuited/
opened. The function is dened in o02.

DI2

Digital input signal.
The dened function is active when the input is short-circuited/
opened. The function is dened in o37.

Pressure transmitter

AKS 32R

Connect to terminal 30, 31 and 32.
(Used cable 060G1034: Black=30, Blue=31, Brown=32)
The signal from one pressure transmitter can be received by up
to 10 controllers. But only if there are no signicant pressure
decreases between the evaporators to be controlled.

S2

Pt 1000 ohm sensor

S3, S4, S5

Pt 1000 ohm sensor or PTC 1000 ohm sensor. All have to be of the
same type.

S3, air sensor, placed in the warm air before the evaporator
S4, air sensor, placed in the cold air after the evaporator

(the need for either S3 or S4 can be deselected in the
conguration)

S5, defrost sensor, placed on the evaporator.

EKA Display

If there is external reading/operation of the controller, display type
EKA 163B or EKA 164B can be connected.

RS485 (terminal 51, 52, 53)

For data communication, but only if a data communication
module is inserted in the controller. The module can be a LON
RS485, DANBUSS or a MODBUS.
Terminal 51 = screen
Terminal 52 = A (A+)
Terminal 53 = B (B-)
(For LON RS485 and gateway type AKA 245 the gateway must be
version 6.20 or higher.)

MODBUS

For data communication.
Terminal 56 = screen
Terminal 57 = A+
Terminal 58 = B­(Alternatively the terminals can be connected to an external
display type EKA 163A or 164A, but then they cannot be used
for data communication. Any data communication must then be
carried out by one of the other methods.)

Supply voltage

115 V a.c., 50/60 Hz

DO1

Connection of expansion valve type AKV or AKVA. The coil must
be a 115 V a.c. coil.

DO2

Alarm

There is a connection between terminal 7 and 8 in alarm situations
and when the controller is without power.

DO3

Refrigeration / Railheat

There is connection between terminal 10 and 11 when the
function must be active.

DO4

Defrost

There is connection between terminal 12 and 14 when defrosting
takes place.

DO5

Fan

There is connection between terminal 15 and 16 when the fan is
on.

DO6

Light

There is connection between terminal 17 and 18 when the light
must be on.

DI3

Digital input signal.
The signal must have a voltage of 0 / 115 V a.c..
The function is dened in o84.
