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

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 tempe ROOM2 sensor’s temperature) / 2

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.

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.
