The rail heat can be controlled in several ways: 0: Rail-
heat is running all the time 1: Pulse control is used
with a timer function following the day/night opera-
tion 2: Pulse control is used with a dew point function.
This function requires that a signal is received about
the dew point value. The value is measured by a sys-
tem manager and sent to the controller via the data
communication.
0=ON, 1=Day/Night timer, 2=Dew point ctrl.
Railheat power during day time. The ON period is set
as a percentage of the period
Railheat power during night time. The ON period is

Periodtime for pulsing of railheat
Rail heat PWM - Peri-
od time
Period time for the pulse width modulation
Lowest permitted rail heat power. When the meas-
ured dew point is below the dened minimum limit
the rail heat will run with the set minimum power
If the measuered dew point is below the set value the
rail heat is running at minimum heat
If the measured dew point is above the set value the
rail heat is maximum

Conguration 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 o.
4: As "2" but if there are any 15-minute network errors,
the light will switch on and the night blind will open.
5: Light is controlled via DI input signal

Main switch OFF 0: Light is switched o and night
blinds are open when the main switch is o 1: Light
and night blinds are independent of main switch.

The status of the function can be followed 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 O. 2 = Cleaning
with stopped fans. All outputs are O. If the function
is controlled by a digital input signal, the relevant sta-
tus can be seen here in the menu.
0=OFF, 1=Fans run, 2=Cleaning
