Note:

For recirculating air defrost ("cd" "FAn"), the fan is switched on during the defrost phase regardless of

the configuration given here.

Defrost communication with linked defrost start (dLL)

Using electric defrost ("EL"), switching on the configured digital input results in a defrost phase after

the expiration of all minimum runtimes (cooling demand, fan, ...). After finishing the defrost, fan and

cooling demand are suppressed until the input signal is cancelled. 90 minutes after finishing the

defrost the controller is starting his regular function even if the input signal is not released. A defrost

is not allowed, if the signal for defrost suppression is switched on, or the last defrost happened less

then 1 hour ago. However, the defrost request is saved and carried out after the removal of the

internal lock.

Using recirculating air- or hot gas defrost ("FAn", "HGE" and "HGS"), the "standard" defrost

communication is carried out (see below).

Attention: When using defrost communication with the digital inputs 1 or 2, the goods protection

program should not be configured. Nonobservance results in the alert "EUS".

Cooling request suppression (cSU)

The cooling request is suppressed or interrupted after the minimum running time has elapsed for the

duration of the connection of the digital input or for a maximum of one hour. The fan management is

not affected by this.

Defrost suppression (dSU)

External defrost suppression only takes place after connection of the corresponding configured

digital input. After cancelling the defrost suppression, a defrost can be initiated 1 hour after the

cooling request at the earliest. A defrost that has already been initiated is not interrupted.

Temperature communication (Ecd)

Two MIC QKL mini 2's are also able to communicate with each other using their digital inputs without

a network module. An adaptive setpoint correction of more than two controllers can only be

established using optional network modules, as described under the operating level 2.2.

Directly after a controller requests cooling, a temporarily adjustment of the setpoint temperature of

the remaining controller takes place for the duration of the cooling request. The adapted setpoint

temperature is displayed in the operating level 1 under ''tSA''. The controller percieves the new

setpoint temperature and starts his cooler fan first , followed by his cooling request in the event of a

tendentiously increasing room temperature.

If the remaining controllers of the cooling position detect a tendentially falling room temperature, their

cooling contactor remains inactive whereas the cooler fans remain switched on. After the controller

which initially requested cooling reaches his setpoint temperature, the cooling request and the cooler

fans are switched off under consideration of minimum runtimes. The air cooler fan management as

configured under ''cFA'' is used again. The original setpoint temperature has now priority even for the

former adapted controller.

The procedure described above enables room-temperature driven compressor capacity-control to

be implemented easily.

You can obtain more information on temperature communication with its various possible

applications directly from Cool Expert on request.

Setpoint shift with defrost suppression (SH2)

For the duration of the connection the setpoint value is adjusted by the value configured under "cSS".

During this time, no defrost can be initiated. A defrost that has already been initiated is not interrupted.

The "new" setpoint value is displayed in operating level 1 under "tSA".

Defrost initiation (Edd)

Once all minimum runtimes have expired (cooling request, fan...), a defrosting process is initiated. A

defrost is not permitted if the signal of the defrost suppression is active or the last defrost took place

within less than one hour.

Defrost communication (dLC)

Multiple controllers can work together as a group in one or in several refrigerated units after initiating

a defrost in order to achieve an optimum defrost result. A defrosting controller blocks all other

controllers of a group and thus prevents the occurrence of cost-intensive peak loads. The functions

mentioned below are implemented for the duration of the connection of the configured digital input

regardless of the defrosting procedure selected.

For electric defrosting if the configuration "EL" is selected under "cD". The controller is switched to

standby (a maximum of one hour) for the duration of the connection of the correspondingly

configured digital input. After cancelling the signal, a defrost can be initiated 1 hour after the cooling

request at the earliest.

For hot gas defrosting in interconnected and individual refrigeration systems if the configuration

"HGE" or "HGS" is selected under "cd". The controller is switched to cooling request to generate hot

gas (for a maximum of one hour) for the duration of the connection of the correspondingly configured

digital input, regardless of the room temperature. After cancelling the signal, a defrost can already

be initiated after 5 minutes of cooling request.

Recirculating air defrosting if the configuration "FAN" is selected under "cD".

After the correspondingly configured digital input is connected, a defrosting process is also initiated.

If the signal continues after finishing the defrost, the controller is switched to standby. The controller

switches to normal operation after one hour at most. After cancelling the signal, a defrost can be

reinitiated after two-hours of cooling request at the earliest.

Attention: When using defrost communication with the digital inputs 1 or 2, the goods protection

program should not be configured. Nonobservance results in the alert "EUS".

You can obtain more information on defrost communication with its various possible applications

directly from Cool Expert on request .

Standby (Stb)

The standby mode is initiated immediately for the duration of the connection. The message "Stb"

appears alternately with the room temperature "tL1"in the display. After cancelling the signal, the

controller remains locked for 8 minutes more. This delay time can be adjusted in operating level 2.1,

item "iSd". A safety time can be configured under "cSd". Even in the case of continuous connection

of the digital input, the controller reassumes its control function after the safety time has expired.

Note:

An ongoing defrost is interrupted by the standby and resumed after cancelling the signal.

Detection of a door opening (dC)

The cooling request and fan run are suppressed or interrupted immediately (regardless of all

minimum runtimes). The message "-d-" is displayed alternately with the room temperature for the

duration of door opening.The duration of the door opening in conjunction with "cdd" as well as a

safety temperature under "cdt" can be configured in order to protect the goods against damage.

Setpoint shift (SH1)

The setpoint value is increased or decreased for the duration of the connection by the value

configured under "cSS" and displayed in the operating level 1 under "tSA".

Input not configured (OFF)

No function is performed during connection of the input.

Attention:

The functions of the digital inputs 1 and 2 described here may only be connected using potential-free

contacts.

Correction of the setpoint temperature

If the digital input has been configured accordingly, the setpoint temperature can be increased or

decreased from -30 to +30 K / -54 to +53.5 °R here.

Note:

If circulating air defrosting is used ("cd", "FAn") the resulting setpoint value must not be set to less

than 0 °C / 32 °F! The alert "EUS" follows if this is disregarded.
