Description
"tHE
Thermostat settings
"SEt"
Min. -100.0°C
Max. 200.0°C
Default 2.0°C
Set point
This parameter defines the desired temperature (set point).
In standard operation the set point is changed by simply pressing the
"
temperature up/down
" buttons on ERC 112D VSC; for laboratory and
assembly line you may opt for software controlled set point adjustment
(speed improvement)
"SPr"
Min. 0.0
Max. 1.0
Default 0.5
Current set point adjustment value diF * SPr
The default value is set to 0.5 and the parameter is hidden by default.
"
Spr
" defines the position of the set point in relation to cut-in and cut-out.
"
Spr=0,5
" sets the set point mid between cut-in and cut-out.
"Spr=0" sets
the set point at the cutout. "
Spr=1
" sets the set point at cut-in.
"diF"
Min. 0.0 K
Max. 20.0 K
Default 2.0 K
Thermostat differential
This defines the difference between the cut-out and the cut-in.
The desired temperature is determined by "
SPr
" and "
diF
".
"HSE"
Min. -100.0°C
Max. 200.0°C
Default 50.0°C
Upper limit of thermostat set point
Define the temperature range limit of the controller.
Once set, the desired temperatue (set point) can not go above "
HSE
" or
below "
LSE
".
"LSE"
Min. -100.0°C
Max. 200°C
Default -35.0°C
Lower limit of thermostat set point
Define the temperature range limit of the controller.
Once set, the desired temperatue (set point) can not go below "
LSE
".
"iCi"
Min. no
Max. yes
Default no
Initial cut in
This parameter is to set the refrigeration system action when cab air temperature is between cut-in and cut-out at power up.
yES : Switch on the refrigeration system immediately.
no: Keep the refrigeration system off until cab air temp reaches cut in temperature.
FAn
Fan settings
"FCt"
Default FAo
Fan control method
"
FAo
": fan always on
"
SEt
": fan follow compressor by manual settings. (FoC and FSC needs to be set accordingly)
"
Aut
": automatical fan control
"Fod"
Min. 0 s
Max. 240 s
Default 0 s
Fan ON Delay/Fod
Fod defines the fan delay (in seconds) after a compressor cut-in.
Fan Stop Delay/FSd
"
FSd
" defines the fan delay after a compressor cut-out.
If both "
Fod
" and "
FSd
" are set to zero then the fan runs whenever the
compressor runs.
"FSd"
Min. 0 s
Max. 240 s
Default 0 s
"FoC"
Min. 0 s
Max. 960 s
Default 0 s
Fan ON Cycle/FoC
Fan Stop Cycle/FSC
When the compressor is OFF, and "
FoC
" or "
FSC
" are not zero, the fan
runs in cycles according to "
FoC
" and "
FSC
".
Example: "
FoC=120
" [sec] and "
FSC=120
" [sec] means that the fan runs
for half the time when the compressor is OFF. When the compressor is
on, the fan is always ON (according to "
FAo
" and "
Fod
").
"FSC"
Min. 0 s
Max. 960 s
Default 0 s
"FSt"
Min. 0 s
Max. 960 s
Default 10 s
Fan Minimum Stop time
Minimum stop time for fan protection.
"FdC"
Min. -10.0 K
Max. 10.0 K
Default 0.0 K
Fan Δt cut in
(This parameter is only applicable with Automatic fan control "Aut" mode.)
Delta T for fan to cut in which the temperature offset comparing with
thermostat cut in temperature.
