DI1

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

DI2

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

Pressure transmitter or temperature sensor S1

Pe / AKS 32R (pressure measurement recommended)

Connect to terminal 30, 31 and 32.
The signal from one pressure transmitter can be received by up 
to 10 controllers. But only if there are no significant pressure 
decreases between the evaporators to be controlled.

S1 (correct location is important to ensure correct measurements)

Pt 1000 ohm sensor
Connect to terminal 31 and 32. 

S2

Pt 1000 ohm sensor

S3, S4, S5, S6

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 
configuration) 

S5, defrost sensor, placed on the evaporator
S6, product sensor or defrost sensor B or air sensor B. 

The configuration determines which.

EKA Display

If there is be 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.)

RJ45

For data communication, but only if a TCP/IP module is inserted in 
the controller. (OEM)

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

230 V a.c., 50/60 Hz

Connections

Version where sensor 
connections have plug 
connections.
