Configuration parameters can only be set when the regulation is
stopped, r12=0):.
Function
Normal display
A display of the regulated temperature
can be seen in EKA 164. (display with
buttons)
Shows Pc in EKA 163
Reference
Select unit (0=bar and °C, 1=Psig and
°F)
Start/Stop of regulation
Set regulation setpoint
Shows the total reference
Limitation: reference max. value
Limitation: reference min. value
Correction of signal from Pc-sensor
Pc reference variation.1 and 2 are PI-
regulation
1: Fixed reference. "r28" is used
2: Variable reference. Outdoor tempera-
ture (Sc3) included in the reference
3: As 1, but with P-regulation (Xp-band)
4: As 2, but with P-regulation (Xp-band)
5: As 1, but with min.-reference acc. to
outdoor temperature
6: As 3, but with min.-reference acc. to
outdoor temperature
The mean temperature difference
across the condenser at the lowest
relevant capacity (min tm K)
This is where you can see the actual
temperature that is part of the regula-
tion.
Set point settings for heat recovery
Average period for reference changes. r65
Displacement of reference at external
signal = 10 V
Displacement of reference at external
signal = 0 V
Correction of signal from S7-sensor
Correction of signal from S8-sensor
Capacity
Definition of fan relay
1-6: Total number of fan relays in
sequential operation.
7-10: Not used
11- 16: Total number of fan relays in
cyclic operation.
Definition of the analoge output volt-
age 0-10 V
1: 0-10 V, linear
2: 10-0 V, linear
3: 0-10 V, unlinear
4: 10-0 V, unlinear

Manual control of condenser capacity
(when ON, the value in "n52" will be
used)
Proportional band Xp for (P= 100/Xp)
fan regulation
I: Integration time Tn for fan regulation n61
Definition of where the first fan is
connected. Set as a % of the total
refrigeration capacity. Ex. 50%, if a
three-way valve is also used.
Alarm
Delay time for a DI1 alarm
Delay time for a DI2 alarm
Delay time for a DI3 alarm
Upper alarm and safety limit for Pc
Pump alarm delay
Miscellaneous
Controllers address
On/off switch (service-pin message)
Access code
Used sensor type for Sc3, S7 and S8
0=Pt1000, 1=PTC1000
Set supply voltage frequency
Manual control of outputs:
0: No override
1-10: 1 will cut in relay 1, 2 relay 2, etc.
11-18: Gives voltage signal on the
analog output. (11 gives 1.25 V, and so
on in steps of 1.25 V
Use of DI4-input
0=not used. 1=Safety signal from high
pressure pressostat
