Delay of output signal after start-up
After start-up or a power failure the controller’s functions can be delayed so that overload-
ing of the electricity supply network is avoided.
Here you can set the time delay.

Digital input signal - DI1
The controller has a digital input 1 which can be used for one of the following functions:
O: The input is not used
1) Status display of a contact function
2) Door function. When the input is open it signals that the door is open. The refrigera-
tion and the fans are stopped and light switched on. When the time setting in “A04” is
passed, an alarm will be given. The refrigeration will be resumed when time in o89 has
passed.
3) Door alarm. When the input is open it signals that the door is open and light on. When
the time setting in “A04” is passed, there will be alarm.
4) Defrost. The function is started with a pulse signal. The controller will register when the
DI input is activated. The controller will then start a defrost cycle.
5) Main switch. Regulation is carried out when the input is closed, and regulation is
stopped when the input is put in pos. OFF.
6) Night operation. When the input is closed, there will be regulation for night operation.
7) Thermostat band changeover. Switch to thermostat 2 (r21) when input is closed.
8) Separate alarm function. Alarm will be given when the input is closed.
9) Separate alarm function. Alarm will be given when the input is opened. (For 8 and 9 the
time delay is set in A27)
10) Case cleaning. The function is started with a pulse signal. See also description on page
5.
11) Forced refrigeration used (at hotgas defrost) when the input is closed.
12) Night blinds. Pulse signal activates the night blinds.
13,14) Not used
15) Case Shutdown when input is closed.

DI state
(Measurement)
The DI input’s present status is shown
here. ON or OFF.
If the controller is built into a network with data communication, it must have an address,
and the master gateway of the data communication must then know this address.
Address
The address is set between 0 and 240, depending on the system unit and the selected data
communication. If the system unit is gateway type AKA 245, the version must be 6.20 or
higher.
Service pin (LON only)
o03
The address is sent to the gateway when the menu is set in pos. ON
IMPORTANT: Before you set o04, you MUST set o61. Otherwise you will be transmitting
incorrect data.
(The function is not used when the data communication is MODBUS)
o04
Access code 1 (Access to all settings)
If the settings in the controller are to be protected with an access code you can set a
numerical value between 0 and 100. If not, you can cancel the function with setting 0. (99
will always give you access).
o05 Acc. code
Sensor type for S3, S4, S5, S6
Normally a Pt 1000 sensor with great signal accuracy is used. But you can also use a sensor
with another signal accuracy. That may either be a PTC sensor (1000 ohm at 25°C)
All the mounted sensors S3-S6 must be of the same type.

Pt = 0
PTC = 1

Max. standby time after coordinated defrost
When a controller has completed a defrost it will wait for a signal which tells that the
refrigeration may be resumed. If this signal fails to appear for one reason or another, the
controller will itself start the refrigeration when this standby time has elapsed.
o16 Max HoldTime
Select signal for the display S4%
Here you dene the signal to be shown by the display.
S3, S4, or a combination of the two.
With setting 0% only S3 is used. With 100% only S4.
