Load request @@&name@@
Determination of a load-dependent enabling for the 2nd (or another) level of a ventilation system. The 2nd level can be requested whenever there is a shortfall or overstepping or both.
If the actual value of the parameter to be monitored for the period of the switch-on delay is outside the starting hysteresis (set point plus/minus of the set hysteresis), the 2nd level is enabled.
If the actual value for the period of the switch-off delay lies within the switch-off hysteresis, the enabling of the 2nd level is cancelled.
In case of shortfall
The enabling of the 2nd level takes place if the actual value lies below the set point minus switch-on hysteresis for the period of the switch-on delay. If the actual value is greater than the set point minus switch-off hysteresis for the period of the switch-off delay, the enabling of the 2nd level is cancelled. Select this setting if the 2nd level should be switched on in case of low actual values.
In case of overstepping
The enabling of the 2nd level takes place if the actual value lies above the set point plus switch-on hysteresis for the period of the switch-on delay. If the actual value is smaller than the set point plus switch-off hysteresis for the period of the switch-off delay, the enabling of the 2nd level is cancelled. Select this setting if the 2nd level should be switched on in case of high actual values.
