"CFu"
Display Unit
This parameter sets the display to Fahrenheit or Celsius. Switching from
Min. °C
one to the other will cause all temperature settings to be automatically
Max. °F
updated accordingly.
Default °C
"trS"
Temp sensor to display
"SCo": temperature control.
Default SCo
"EuA": evaporator temperture.
"Con": condenser temperature (condenser cleaning).
"AuS": only for showing on display.
"rES"
Display Resolution
This parameter can be set to 0.1, 0.5 or 1 and affects the way the
Min. 0.1
temperature is displayed. With the parameter set to 1, the display will
Max. 1
only ever show temperatures rounded to the nearest whole degree.
Default 0.1
At 0.5, it will round the temperature to the nearest half degree for display.
For example, 3.3 degrees will be shown in the display as 3.5 degrees
and 3.9 as 4.0. With the parameter set to 0.1, no rounding occurs.
This parameter does not affect the temperature itself, merely the display.
"rLt"
Display Range Limit
In some point of sales applications you may want to show the desired
Min. no
instead of the real temperature. This parameter sets whether the
Max. yes
displayed temperature is the actual temperature or whether it is restricted
Default no
to the cut-in / cut-out limits. Set to "nO" means that the actual temperature
will de displayed. The parameter is set to "nO" by default.
"ddL"
Display Delay
In order to provide a realistic temperature appearance for an application,
Min. 0 min.
a display delay can be set.
Max. 10 min
The parameter sets the time constant τ (tau) of the moving average filter
Default 0 min
for the display.
Physically, one time constant represents the time it takes the system's
step-response to reach 66% of its final value and five time-constants
the time it takes to reach 99% of its final value.
"doF"
Display Offset
This parameter is a relative value and allows the temperature displayed
Min. -10.0 K
to be different to the temperature measured.
Max. 10.0 K
For instance, at a measured temperature of 7°C and "doF" set to -2K, the
Default 0.0 K
displayed temperature will be 5°C instead.
"dLt"
Lock Time After Defrost
In order not to show a rising temperature during defrosting, the displayed
Min. 0 min
temperature is locked at the temperature shown at the start of the defrost
Max. 60 min
cycle for the number of minutes set in this parameter.
Default 15 min
"0": no lock.
"SEC"
Show Economy State
If set to "yES", this parameter causes the display to show ECO when the
Min. no
system is in ECO mode.
Max. yes
If set to "nO", the temperature continues to be displayed.
Default no
"SSC"
Show Pull down state
If set to "yES", this parameter causes the display to show SC when the
Min. no
system is in pull down mode.
Max. yes
If set to "nO", the temperature continues to be displayed.
Default no
"SHo"
Show Holiday
"no": display will show temperature or ECO mode during holiday mode.
Min. no
"yES": display will show "HoL" during holiday mode.
Max. yes
Default no
