Setting
60 sec%
3 sec Sets the pulse time that the speed filter will be performed to the fan analog output.
0.020
inWC
Sets the proportional band for which the fan speed modulation output calculation is based
upon in relation to the difference between the pressure reading the SP Setpoint.
5 Pa
Sets the use of static pressure control if dehumidification becomes active. It set to Disabled
then the static pressure routines will become inactive and the fan will be allowed to ramp to
Disabled
the dehumidification speed set in Fan speed Dehum/No Power. If set to "Enabled", then the
static pressure routines shall remain active during the call for dehumidification.
There are modes available for static pressure teamwork functionality: Average & Minimum.
When selecting "Average Mode", the average of the lowest static pressure sensor readings in
the system will be average to generate a shared static pressure value for all units in the team.
Average
The number of static pressure sensors to be averaged is set in line S198 SP Sensors in Avg for
TW. When this line is set to a value lower than the number of units in the team, the lowest
static pressure readings will be averaged.
2 Sets the number of sensors used when averaging sensors in the teamwork.
This parameter determines what action to take if the static pressure sensor fails (non-
teamwork). If "SP OFF" is selected, then the control will use S146 "Fan Control Sensor" to
SP Off control the fan when the sensor is lost. If "Freeze Speed" is selected, then the control will keep
the fan speed in its last known position. Situations that need to override the fan speed such as
Freeze Protection can still change the fan speed.
