Operation
Display
The values will be shown with three digits, and with a setting you
can determine whether the pressures are to be shown in °C or i °F.
EKA 162
For operation and display of
evaporating pressure. The
light-emitting diodes on the
left-hand side fl ash when
there is an alarm.
The buttons
When you want to change a setting, the two buttons will give you
a higher or lower value depending on the button you are push-
ing. But before you change the value, you must have access to the
menu. You obtain this by pushing the upper button for a couple
of seconds - you will then enter the column with parameter codes.
Find the parameter code you want to change and push the two
buttons simultaneously. When you have changed the value, save
the new value by once more pushing the two buttons simultane-
ously.

Gives access to changes
Saves a change
Operation
1. Push the upper button until a parameter is shown
2. Push one of the buttons and fi nd the parameter you want to
change
3. Push both buttons simultaneously until the parameter value is
shown
4. Push one of the buttons and select the new value
5. Push both buttons again to conclude the setting
During operation it is possible to show the condensing pressure
on the display EKA 162 by pushing the lower button short.
Quick- start
If you wish to start the system in a hurry so that refrigeration can
be commenced you can set the following eight parameters: r23
– r28 – c08 – c09 – c16 – c29 – o30, and fi nally r12.
When regulation has then started you can go through the
remaining parameters and adjust these.

Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you recon nect the supply voltage

1: Fixed reference. "r28" is used
2: Variable reference. Outdoor tempera-
ture (Sc3) included in the reference

Capacity
Min. ON time for relays
Min. time period between cutins of same
relay
Defi nition of regulation mode
1: Sequential (step mode / FILO)
2: Cyclic (step mode / FIFO)
3: Binary and cyclic
If a regulation mode with unloaders is
selected, the relay must be defi ned to:
0: Cut in when more capacity is required
1: Cut out when more capacity is required
Regulation parameter for + Zone
Regulation parameter for + Zone
Regulation parameter for ++ Zone
Regulation parameter for - Zone
Regulation parameter for - Zone
Regulation parameter for - - Zone
Defi nition of compressor connections.See
options on page 10.
The following "c17" to "c28" is only relevant
if "c16" has been selected to 0.
A code will then have to be set for the
relays that are to be ON at the diff erent
steps:
Step 1 (M&M operation)
Step 2 (M&M operation)
Step 3 (M&M operation)
* also applies to regulation with reference displacement
