Comp. Safety delay Delay time before compressors cut out for reasons of safety
The time begins when a signal is received on the DI input (configure the DI input via
“Configuration” and “Comp. safety inlet”).
Min: 1 min.
Max: 10 min
Fac: 0 min
Compressor status Compressor status
Comp. 1 Sd gas Read the Sd temperature of the compressor here.
Comp. 1 status Read the operating status for compressor 1 here. The following information may appear:
Alarm - Alarm situation
Main Sw. off - Compressor is stopped
Manual ctrl. - Compressor is cut out on safety input (DI safety input)
High Sd temp. - Stopped due to high Sd temperature
Ready - Compressor is ready to start
OFF timer - Compressor is waiting for Min OFF timer to expire
Min. ON timer - Compressor is waiting for Min ON timer to expire
Running - Compressor is running
Disabled - Compressor has been taken out of operation (compressor service)
Comp. 2.... The same function for the remaining compressors
Compressor capacity Compressor capacity
Comp. 1 cap Read the connected capacity of the compressor (0-100%) here
Comp. 2...... The same function for the remaining compressors
Compressor runhours Compressor run hours
Reset runtime/cycles Reset all of the hour counters and start counters for the subsequent compressors here.
Comp.1 Runtime L Read the total operating time of the compressor (in hours) here
Comp.2..... The same function for the remaining compressors
Compressor cycles Compressor cycles
Comp.1 Cycle total Read the number of times the compressor has been started here
Comp.2..... The same function for the remaining compressors
Compressor service Compressor service
Comp.1 out of service The compressor can be taken out of operation, so that the controller regulates without this
compressor.
No = Normal regulation
Yes = Regulating is carried out without this compressor, and no alarms are generated by it.
Yes /No
Fac: No
Comp.2..... The same function for the remaining compressors
Suction B
Suction group B. Please see descriptions under suction group A
(Bitzer CRII can not be used in suction group B.)
Condenser
Control status Regulation status
Control status Here you can read the status of the condenser circuit, e.g.:
• Main Sw. off - Main switch = OFF
• Ready - Capacity control is ready
• Running - Capacity control is in normal run mode
• Capacity control is stopped because all compressors are stopped
• Manual ctrl - Capacity control is set in manual control mode
• High Pc/Sd - Capacity forced to 100% due to High Pc/High Sd prevention functions
• Safety limit - Capacity forced to 100% due to external HP switch/HP safety/Sd safety limit
violation
• Night limit - Capacity control limited due to night silencer limitation
Control temp. The current value of the regulation sensor can be read here
Reference The total regulation reference can be read here
Running capacity Here the connected capacity can be read as a % of total capacity
Requested capacity Here the preferred connected capacity can be read as a % of total capacity
No. of running fans The number of fans in operation can be read here
Tc Saturated temp. The measured Pc pressure converted to temperature can be read here
Pc Pressure The measured pressure for pressure transmitter Pc can be read here
S7 Media Here the measured media temperature with sensor S7 can be read (only if S7 has been
selected as the regulation sensor during “Fan configuration”)
Sc3 air on cond. The measured outdoor temperature with sensor Sc3 can be read here
Heat recovery status Here the status of the heat recovery function can be read
HP safety switch The status of the HP safety switch can be read here
Control settings Control settings
Control mode Regulation type
The regulation is normally set to “Auto”, but it can be changed to “Off” or “Manual”.
When setting to “Manual”, capacity can then be forced set in %.
MAN / OFF / AUTO
Fac: AUTO
Min: 0 %
Max: 100%
Setpoint Enter the set point for the condenser regulation here.
Also set a value if regulating with a fluid reference (set point value used in the event of an
outside temperature sensor error).
Min: -25°C (-1.0 bar)
Max: 90°C (159 bar)
Fac: 35°C (15.0 bar)
