Rail heat control
mode
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.

Lowest permitted rail heat power. When the meas-
ured dew point is below the defined minimum limit
the rail heat will run with the set minimum power

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 errors,
the light will switch on and the night blind will open.
5: Light is controlled via DI input signal

Case cleaning mode 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 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.
