ERC menu code Description
"tHE Thermostat settings
"SEt" Set point
This parameter defines the desired temperature (set point).
Min. -100.0°C
In standard operation the set point is changed by simply pressing the
Max. 200.0°C
"temperature up/down" buttons on ERC 112D VSC; for laboratory and
Default 2.0°C
assembly line you may opt for software controlled set point adjustment
(speed improvement)
"SPr" Current set point adjustment value diF * SPr
The default value is set to 0.5 and the parameter is hidden by default.
Min. 0.0
"Spr" defines the position of the set point in relation to cut-in and cut-out.
Max. 1.0
Default 0.5 "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" Thermostat differential
This defines the difference between the cut-out and the cut-in.
Min. 0.0 K
The desired temperature is determined by "SPr" and "diF".
Max. 20.0 K
Default 2.0 K
"HSE" Upper limit of thermostat set point
Define the temperature range limit of the controller.
Min. -100.0°C
Once set, the desired temperatue (set point) can not go above "HSE" or
Max. 200.0°C
Default 50.0°C below "LSE".
"LSE" Lower limit of thermostat set point
Define the temperature range limit of the controller.
Min. -100.0°C
Once set, the desired temperatue (set point) can not go below "LSE".
Max. 200°C
Default -35.0°C
"iCi" 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.
Min. no
yES : Switch on the refrigeration system immediately.
Max. yes
no: Keep the refrigeration system off until cab air temp reaches cut in temperature.
Default no
FAn

Fan settings

"FCt"
Fan control method
"FAo": fan always on
Default FAo
"SEt": fan follow compressor by manual settings. (FoC and FSC needs to be set accordingly)
"Aut": automatical fan control
"Fod"
Fan ON Delay/Fod
Fod defines the fan delay (in seconds) after a compressor cut-in.
Min. 0 s
Max. 240 s
Fan Stop Delay/FSd
Default 0 s
"FSd" defines the fan delay after a compressor cut-out.
"FSd"
If both "Fod" and "FSd" are set to zero then the fan runs whenever the
Min. 0 s
compressor runs.
Max. 240 s
Default 0 s
"FoC"
Fan ON Cycle/FoC
Fan Stop Cycle/FSC
Min. 0 s
When the compressor is OFF, and "FoC" or "FSC" are not zero, the fan
Max. 960 s
runs in cycles according to "FoC" and "FSC".
Default 0 s
"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
Min. 0 s
Max. 960 s
on, the fan is always ON (according to "FAo" and "Fod").
Default 0 s
"FSt" Fan Minimum Stop time
Minimum stop time for fan protection.
Min. 0 s
Max. 960 s
Default 10 s
"FdC" Fan Δt cut in
(This parameter is only applicable with Automatic fan control "Aut" mode.)
Min. -10.0 K
Delta T for fan to cut in which the temperature offset comparing with
Max. 10.0 K
thermostat cut in temperature.
Default 0.0 K
