SETTING
2 C11
Setpoint for activating the
additional unit (authorisation
setpoint)
15 to 40°C
(but always 2 K greater than the highest of
the P103 cooling setpoints for the units
currently operating)
27°C C02 = 1
2 C12 Unit rotation time delay
Value adjustable from 0 to 240 h (value '0'
is used for testing and corresponds to a
period of 5 minutes)
168 h C05 = 1
2 C13
Number of days between 2
restarts
Value adjustable from 0 to 60 days
(value 0 is used for testing and corresponds
to a period of 5 minutes between 2 restarts)
30 d C05 = 2
2 C14 Restart time
Hours/Minutes
(this setting is not taken into account if
parameter C13=0)
8.00 am C05 = 2
2 C15 Restart period 5 to 300 mins. 30 mins. C05 = 2
2 C16 Cooling setpoint shift at restart 0 to 5 °C 3°C C05 = 2
READ-ONLY
1 C21 Unit rotation counter
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.
C05 = 1
1 C22
Additional unit setpoint (setpoint
calculated)
Note: This gives the actual value of the
setpoint, i.e. at least 2 K above the highest
cooling setpoint for all units
C02 = 1
1 C23
Number of days before periodic
restart
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.
j C05 = 2
1 C24
Time before the end of the
periodic start
Note: this counter displays the time
remaining before the end of the periodic
restart
mins C05 = 2
1 C29 Software version number
