6.4.6.5 TECHNICIAN VENTILATION PARAMETERS
1. Shifting fans (FAN CONT.:TUNNEL):
When VENTIL. PARAMETERS PAGE SHIFT&PRP PER parameter is
expired, working fan number is shifted right once.
For example; 6. and 7. Fans are active and 8. Fan operates proportional
in Figure1
3. Delay between fans
Two fans can not be switched on at the same time. Second fan switched on after VENTIL. PARAMETERS
PAGE DLY BTWN FANS time is over.

Output
0%
Time [sec]
100%
4. Output Filter
Process Output rises from 0% to 100% in VENTIL. PARAMETERS PAGE PRPRTN RAMP period.
This feature is called Output Filter.
4. Sensor Selection
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM1;
Temperature = ROOM1 sensor’s temperature
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM2;
Temperature = ROOM2 sensor’s temperature
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM1&2;
Temperature =( ROOM1 sensor’s temperature + ROOM2 sensor’s temperature) / 2
Figure1
Figure2
When VENTIL. PARAMETERS PAGE SHIFTING&PRP PER parameter is expired, 7. and 8. Fans are active
and first fan operates proportional as in Figure2
If VENTIL. PARAMETERS PAGE SHIFTING parameter is OFF then shifting feature is disabled.
If SHIFTING parameter is CMN then minimum ventilation fans that selected by FAN COUNT BAS
parameters, never shift. Shifting operates on another fans except theese minimum vent fans.
VENTIL. PARAMETERS
SHIFTING : ON
SHIFT&PRP PER: 2MIN
DLY BTWN FANS: 5SEC
PRPRTN RAMP : 50SEC
SENSOR : ROOM1
FAN CONT.: TUNNEL
FAN COUNT BAS:1 TOT:8
61
2. Shifting fans(FAN CONT.:BASIC&TUN.):
When VENTIL. PARAMETERS PAGE SHIFT&PRP PER parameter is
expired, working fan number is shifted right once. Only tunnel fans are shifting on each other.
For example; 3. and 4. Fans are active in Figure3
Figure3
Figure4
When VENTIL. PARAMETERS PAGE SHIFTING&PRP PER parameter is expired, 4. and 5. Fans are active
in Figure4
If VENTIL. PARAMETERS PAGE SHIFTING parameter is OFF then shifting feature is disabled.
