Mix and Match step 1.
This function cuts the relay in and out depending on the denitions in "c17" to"c28".
(“c17” to “c28” only used, if “o61” selected to “3” or "4"). (In Mix and Match couplings the
settings “c08” and c09" are not used).
Step 1
Here in c17 set the relays to be ON at step 1.
Setting takes place with a numerical value representing the combination of relays. See
the survey page 11. Proceed by dening steps two, three, etc.
The denition ends at the rst c18 - c28 which is set to “0”.
The time delays “c01” and “c07” belong to the individual relay outputs. If a relay output
is captured by the time delay, a changeover from one step to another will only take
place when all the relay outputs concerned have been released. The time delay will
not interfere with a relay which is ON in two successive couplings. If a compressor
drops out there will be an alarm. The regulation will continue as emergency operation,
as if the compressor were present.

Step 2. Here you also set a value between 1 and 15. Here in c18 the value will indicate
which relays have to be ON at step 2.

Manual control of compressor capacity
This sets the capacity that is to be cut in when switching to manual control.
(c01 and c07 will still apply)

Manual control
Manual control of the compressor capacity is enabled here.
When set to ON, the capacity that is set in “c31” is cut in.

Condenser capacity
Denition of condenser and number of fans
Here you set the number of fan steps with which regulation has to be carried out (but
max. eight).
1-8: All fans are cut in and out with relays. The rst vacant relay number is assigned to
fan 1, the next to number 2, etc. Steps after DO8 must be executed through connec-
tion of a relay module type EKC 331 to the analog output. Cf. drawing on page 12.
9: All fans controlled via the analog output and a frequency converter.
10: Not used
11-18: Total number of fan relays (as 1-8), but here the starting sequence is altered
after each time all fans are stopped.

Regulation parameters for the condenser regulation
Proportional band xp (P = 100/Xp)
If the Xp value is increased, the regulation becomes steadier
n04 Xp K
I: Integration time Tn
If the Tn value is increased, the regulation becomes steadier
n05 Tn s
Manual control of condenser capacity
This sets the capacity that is to be cut in when switching to manual control.

Manual control
Manual control of the condenser capacity is enabled here.
When set to ON, the capacity that is specied in “n52” is cut in.

Speed control start value
Speed control will only be activated when the capacity requirement reaches this
value.
n54 StartSpeed
Speed control stop value
Speed control will be stopped when the capacity requirement falls below this value.
