Table 40: Guiding
The parameter guiding causes a linear reposition of the control value in dependence of a guiding
value, which is measured by an external sensor. With appropriated parameterization a continuous
increment or decrement of the control value can be caused.
For adjusting how the guiding shall impact to the control value, three settings are necessary: Guiding
value minimum (w
min
), guiding value maximum (w
max
), and setpoint variation at maximum guiding
value (
X).
The settings for the guiding value maximum (w
max
) and minimum (w
min
) describe the range of
temperature in which the guiding starts and ends having impact to the setpoint. The real setpoint
offset indicates the following formula:
X =
X
max
* [(w - w
min
)/(w
max
- w
min
)]
If the guiding shall cause an increment of the setpoint, you have to adjust a positive value for the
setti g “etpoi t a iatio at a i u guidi g alue . If ou ish a de e e t of the setpoi
t, you
ha e to hoose egati e alue fo the setti g “etpoi t a iatio at a i u guidi g alue .
The variation of the setpoint
X is added to the basic comfort setpoint.
A measured temperature value for the guiding above the adjusted maximum value or below the
adjusted minimum value has no effect to the setpoint.
So when the value is between the adjusted guiding values (w
max
& w
min
)
the setpoint is increased or
decreased.
