Comp. 1 Status

Time delay between step cut-outs in the regulation band under the "-Zone band"

Set in seconds.

Amplification factor for P0 regulation

Displacement value for suction pressure in connection with an active night

setback signal (set in Kelvin)

Reference temperature for the temperature signal S3, i.e. when = Tref, there is no

displacement of the reference.

Displacement of the reference for the charge temperature S4 on an increase in S3

temperature in relation to "Tref S3 offset" of 1°C (K1 = 0 gives no displacement)

Max. permissible suction pressure reference

Min. permissible suction pressure reference

Minimum allowed speed before stop of Variable Speed drive (Low load condition)

Minimum speed for start of Variable speed drive (Must be set higher than

"VSD Min. Speed Hz")

Highest permissible speed for the compressor motor

Set max capacity limit for load shed input 1

Set max capacity limit for load shed input 2

Set max load shedding override limit for suction pressure Po

Override delay for load shed limit 1. If the suction pressure exceeds

"Override limit Po" during load shedding and the set delay has expired, the load shed

limit 1 will be cancelled

Override delay for load shed limit 2. If the suction pressure exceeds

"Override limit Po" during load shedding and the set delay has expired, the load shed

limit 2 will be cancelled

Set the actual pump down limit for the last compressor

The time after start-up where the cut-in capacity is limited to the first compressor step.

On new start the start of the first compressor is delayed by the set delay time so that the

brine pumps can bring the brine up to speed before start of the first compressor.

A relay is reserved and it will be activated if the brine temperature is higher than

desired.

Set the value (K above the reference) where the relay is to activated

Delay time before the relay can be active. The time applies during normal regulation

Delay time before the relay can be active. The time applies during cooling after start-up

and after defrosting.

When "ON", the controller is in alarm condition.

Actual temperature for compressor control

Actual cold brine supply temperature measured with S4 temp. sensor

Actual cold brine return temperature measured with S3 temp. sensor

Suction pressure in °C. (Measured with the pressure transmitter)

Actual reference temperature for compressor control

Cut-in compressor capacity in % (of total capacity)

Reference for compressor capacity (deviations may be due to time delays)

Actual temperature for control sensor (Pc or S7)

Actual warm brine temperature for S7 media sensor

(Only used if S7 sensor is selected as regulation sensor)

Condensing pressure in °C. (measured with the pressure transmitter)

Actual reference temp. for condenser capacity

(incl. external reference signal, if any)

Cut-in condenser capacity in % (of total capacity)

Reference for condenser capacity
