ERC menu code 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 112; 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
Comp relay action when Tair is between cut-in and cut-out at power-up:
"yES": cut in the compressor.
"no": cut out the compressor.
"SP2"
Min. -25 K
Max. 25 K
Default 0
Seasonal offset temperature (This parameter is only available from Product version PV03 onwards. Please check product label
for Product version of your controller.)
Offset value for set point and alarms when the seasonal offset button is activated.
It is an additional offset mode to have separate set points during summer and winter season, which can be activated by long
press button after configuring in assignments as "tEc".
"dF2"
Min. 0 K
Max. 20 K
Default 2
Seasonal differential
Temperature differential during seasonal offset mode. Only applicable during normal operation.
During ECO mode, the controller will be worked to the ECO Differential setting. See ECO management section for more details.
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
