8.5.2 Stepless Regulation of Cooling
At COOL AGGREGATE = 2, a control signal of 0 - 10V
DC is maintained on plinth 11 (+) and 12 (-) for
regulation of stepless cooling. (See 3.8.2)
A neutral zone of 2
°
C. is allowed, as above.
When cooling is needed, the control signal is regulated
steplessly so that the set value increases while the
neutral zone is maintained.
SA-MIN maintains temperature limits for Supply Air
upon Exhaust Air regulation.
A closed contact between plinths 17 and 18 is also
maintained with this function when cooling is needed
and the temperature rises above the set value
including the neutral zone.
When the temperature has gone down to 0.5 degrees
above the set value, the contact opens and a restart
time of 10 minutes begins to run.
The contact also opens when SA-MIN goes below the
set value upon Exhaust Air regulation.
8.6 Duct calibration
At DUCT CALIBR = 1 (on).
The unit is operating on a firm calibration flow and
measures where in the flow diagram the unit is operating
with care taken to connected duct system and with clean
filters.
Duct calibration shall always be carried out when
alterations in the duct system have been carried out.
Set the duct calibration to 1 and go to "main menu" Auto
oper or Manual oper.
Duct calibration is carried out and 1 automatically
changes to 0 when the unit has stored the calibration
value and returned to normal operation (after appr. 5 min).
8.7 Service period
Shows how many months remaining until service period
alarm is released. The programming is carried out in
months.
Resetting of alarm is carried out via programming SERV
PERIOD to the next service interval.
