23
Factor
Setting of the extent of outside temperature influence.
Outside temperature influence on bandwidth.
Factor outside temperature: 2.5
Set bandwidth: 4.0°C
The controller can increase the bandwidth by factor 2.5 x 4.0°C. The
maximum bandwidth is then 10.0°C.
Outside temperature influence on start temperature ventilation.
Factor outside temperature 2.5
Set bandwidth 4.0°C
The controller calculates a maximum shift of the start temperature
ventilation (heating) of: 2.5 × 4.0 - 4.0 = 6.0°C.
Influence limit (calc)
Readout of the maximum calculated bandwith.
Heat demand heating
Setting if heating influences central pre-control:
 None
 Pre-control 1
 Pre-control 2
 Pre-control 1 & 2
An Aura 14 cannot control a boiler, but transmits the heat demand via Fnet
communication to a controller that can. With types Pre-control 1, Pre-control
2 and Pre-control 1 & 2 the Aura 14 determines the heat demand as the
difference between the measured temperature and the control value. The
Aura 14 transmits the actual difference value (for example -0.8) to the
controller responsible for controlling the heating pre-control. The “coldest”
section in the loop determines the ultimate heat demand.
