Display Unit; Display Resolution - Danfoss ERC 112D VSC User Manual

User Guide | ERC 112D VSC Refrigeration Controller
"CLL" Condenser Low Limit/CLL
This parameter sets the lowest (condenser) temperature at which the
Min. -100°C
compressor is allowed to start.
Max. 20°C
Default -5°C
diS Display settings
NOTE: some display parameters can be set in such as way that they
may be illegal in some jurisdictions. Please check local legislation.
"diC" Display intensity auto control
"no": display intensity use fixed value.
Min. no
Max. yes
Default no
"din" Display Intensity
The controller can have its display intensity (brightness) set in one of
Min. 2
two ways:
Max. 10
A) With a Danfoss ambient light sensor attached, the brightness of the
Default 10
display is adjusted automatically according to the ambient light level
(see the assignments section).
B) When no ambient light sensor is attached, the display intensity can
be set to a fixed intensity.
Both options are on a scale of 1 to 10, where 10 is the brightest.
"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).
"AtP" Weighted average temperature of "SCo" and "EuA"
"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.
