Light/Blinds/Cleaning Control; Display Control - Danfoss AK-CC55 User Manual

AK-CC55 Single Coil and Single Coil UI
Function Description
Rail heat PWM - Peri- Period time for the pulse width modulation
od time
Rail heat min. ON cy- Lowest permitted rail heat power. When the meas-
cle ured dewpoint is below the defined minimum limit
the rail heat will run with the set minimum power
Dewpoint min. limit If the measuered dewpoint is below the set value the
rail heat is running at minimum heat
Dewpoint max. limit If the measured dewpoint is above the set value the
rail heat is maximum

Light/Blinds/Cleaning control

Table 38: Light/Blinds/Cleaning control
Function Description
Control state A Readout of the actual control state of the controller
Night condition Status of the day/night operation (night operation:
on/off)
Light Actual status of output function
Blinds Actual status of output function
Light control mode Configuration of light function1: Light is controlled
via day/night status 2: Light is controlled via data
communication and master control parameter "MC
Light signal" 3: Light is controlled by door contact on
DI input. When the door is opened the relay will cut
in. When the door is closed again there will be a time
delay of two minutes before the light is switched off.
4: As "2" but if there are any 15-minute network er-
rors, the light will switch on and the night blind will
open. 5: Light is controlled via DI input signal
Light at Main switch Define how light and blinds are to be controlled at
OFF Main switch OFF 0: Light is switched off and night
blinds are open when the main switch is off 1: Light
and night blinds are independent of main switch.
Blinds max. open Time delay from when blinds have been opened
time manually until they close again
Case cleaning mode The status of the function can be seen here or the
function can be started manually.0 = Normal opera-
tion (no cleaning) 1 = Only fans are running to defrost
the evaporator. All other outputs are Off. 2 = Cleaning
with stopped fans. All outputs are Off. If the function
is controlled by a digital input signal, the relevant sta-
tus can be seen here in the menu.

Display control

Table 39: Display control
Function Description
Control state A Readout of the actual control state of the controller
Display readout 1 Readout of the temperature shown on the display
Display readout 2 Readout of the temperature shown on the display
Display readout Select which temperature to show in the display
