Configuring The Number Of Units - Carrier CCU Regelungshandbuch

5 - CONFIGURING THE NUMBER OF UNITS

These parameters are only visible if parameter P215 = 1 (master unit)
This sub-menu groups together the operating parameters for the units. They can operate individually or grouped as master/slaves.

1 C29 Software version number
Setting
OPERATING CONFIGURATION
1 to 32: self-contained units
2 to 10: in master/slave
0: No additional unit
1: One additional unit
0: No backup unit
1: One backup unit
0: No additional backup unit
1: One additional backup unit
0: No rotation
(the last unit is the backup unit).
1: Automatic rotation
(according to the time delay adjustable
using C12)
2: Periodic restart
(according to parameters C13 to C16)
0: French
1: English
2: German
3: Spanish
0: Unlocked (the set master/slave functions
are not activated)
1: Locked (the set master/slave functions
are activated).
SETTING
15 to 40°C
(but always 2 K greater than the highest of
the P103 cooling setpoints for the units
currently operating)
Value adjustable from 0 to 240 h (value '0'
is used for testing and corresponds to a
period of 5 minutes)
Value adjustable from 0 to 60 days
(value 0 is used for testing and corresponds
to a period of 5 minutes between 2 restarts)
Hours/Minutes
(this setting is not taken into account if
parameter C13=0)
5 to 300 mins.
READ-ONLY
Note: This counter counts down in
increments and when it reaches 0, it is reset
to the value for C12 and the unit whose
number precedes the stopped unit or units
stops in turn. The unit whose number
precedes those currently operating starts.
Note: This gives the actual value of the
setpoint, i.e. at least 2 K above the highest
cooling setpoint for all units
Note : this counter counts down in
increments every day at 00:00 and when it
reaches 0, the unit on standby starts at the
time set in C14.
Note: this counter displays the time
remaining before the end of the periodic
restart
