Digital input signal - DI1
The controller has a digital input 1 which can be used for one of the following func-
tions:
Off: 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 refrig-
eration and the fans are stopped. When the time setting in “A4” is passed, an alarm
will be given and refrigeration will be resumed.
3) Door alarm. When the input is open it signals that the door is open. When the time
setting in “A4” 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. If the signal
is to be received by several controllers it is important that ALL connections are
mounted the same way (DI to DI and GND to GND).
5) Main switch. Regulation is carried out when the input is short-circuited, and regula-
tion is stopped when the input is put in pos. OFF.
6) Night operation. When the input is short-circuited, there will be regulation for
night operation.
7) Reference displacement when DI1 is short-circuited. Displacement with “r40”.
8) Separate alarm function. Alarm will be given when the input is short-circuited.
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. Cf. also description on
page 4.
11) Forced refrigeration at hotgas defrost when the input is short-circuited.

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.
These settings can only be made when a data communication module has been
mounted in the controller and the installation of the data communication cable has
been finished.
This installation is mentioned in a separate document “RC8AC”.
After installation of a data communi-
cation module the controller can be
operated on an equal footing with the
other controllers in ADAP-KOOL®
refrigeration controls.
The address is set between 1 and 60 (119), gateway determined
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 transmit-
ting incorrect data.
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).

Sensor type
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 1000 sensor (1000
ohm) or an NTC sensor (5000 Ohm at 25°C).
All the mounted sensors must be of the same type.

Yes: Gives steps of 0.5°
No: Gives steps of 0.1°

Max. standby time after coordinated defros
t
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.

Select signal for the display S4%
Here you define 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.
