Optimum room control value
Options:
10…70…90 %
The Room involvement function increases and reduces the supply setpoint
temperature until the highest of the room control values linked to the ASM input
socket reaches this optimum value.
Controller proportional factor Xp
Options:
10…30…90 %
Proportional range of the P controller used for the room involvement. The smaller the
value set, the faster the control reacts. However, the value should not be selected too
small because otherwise there may be a risk of overshoot.
Example:
The value Xp = 30 % means: If the highest control value on the ASM input socket is
30 % below the Optimum room control value, the supply temperature increases by
the full value of Increase supply temperature.
Room involvement calculation delay
Options:
00:00:00…00.45.00…23:59:00 hh:mm:ss
This parameter delays the calculation of the room involvement (and therefore the
increase/reduction of the supply temperature) after starting the device so that the
heating system can reach a steady state.
