Dimensions
The capacity from the digital scroll compressor
The capacity is divided into period times as "PWM period times". 100% capacity is delivered when cooling takes place for the whole
period.
An off time is required by the capacity control valve within the period and an on time is also permitted. There is "no cooling" when the
valve is on.
The controller itself calculates the capacity needed and will then vary it according to the cut-in time of the capacity control valve.
A limit is introduced if low capacity is needed so that the cooling does not go below 10%. This is because the compressor can cool
itself. This value can be increased if necessary.
Refrigeration
No refrigeration
Copeland Stream 4
The signal can also be used to control one stream compressor with one unloading valve.
The compressor capacity is distributed by up to 50% for one relay (start) and the remaining 50-100% for the unloader. The unloader
is connected to DO5 or DO6.
Copeland Stream 6
The signal can also be used to control one stream compressor with two unloading valve.
The compressor capacity is distributed by up to 33% for one relay (start) and the remaining 33-100% for the two unloaders. The un-
loaders is connected to DO5 and DO6.
Bitzer CRII 4
The pulse signal can also be used to control one of the CRII with 2 unloaders (4 cylinders version).
Compressor capacity can be controlled from 10 to 100% depending on the pulsation of the unloaders. The compressor start signal is
connected to a relay output, and the unloaders are connected to DO5 and DO6.
Bitzer CRII 6
The pulse signal can also be used to control one of the CRII with 3 unloaders (6 cylinders version).
The compressor signal is connected to one relay output.
The two unloaders are connected to DO5 and DO6. The third is connected to a relay output.
The compressor capacity can be controlled from 10 to 67%, depending on the pulse of the unloaders.
The relay is then connected to the third unloader. When this relay is on, the capacity will be controlled between 33 and 100%.
