Schedules

Under the schedules section multiple schedules can be added
and congured according to your needs.
Enter the number of schedules required. The desired number of
schedules will be shown (in this example 3 schedules have been
requested). Initially each new schedule is set to disabled, move
the cursor to the required schedule line and press ‘Enter’. The
resulting page allows the denition of the schedule, the following
conguration settings can be made;
• Enable this schedule (ensure this is set to ‘YES’ to engage
schedule)
• Schedule usage (Choose from Misc, Case Lighting, Night
Setback, Shutdown, Defrost, Coord Defrost)
• Description (Add custom description for schedule)
• Schedule control (Choose between Time, Digital, Time &
Digital, Time or Digital)
• Number of schedules (select the number of sub schedules
required)
• Start, Stop, Days and Holidays (Dene the Start / Stop times,
days and holidays)
Each schedule line will also reect the current status

Rail heat settings in the AK-CC550
o85 = Rail heat control (select option 2, pulse control with dew
point function)
o86 = Dew Point MIN limit
o87 = Dew point Max limit
At a dew point which is equal to or lower than the value in 086, the
eect will be the value indicated in o88. In the area between the
two dew point values the controller will manage the power to the
rail heat
For adaptive rail heat to function correctly ensure the AK-CC 550
controllers are set correctly. Review parameters o85, o86 and
o87, as noted below. The screen image below highlights the AK-
CC 550 controller (Miscellanious menu), where parameter o85,
o86 and o87 are set for rail heat control over the bus.
