6. Function blocks
6.1 Manufacturer function blocks
Fig. 168: Offset; O1=-2; O2=-2; Q1=1 will switch on 2 hours before sunrise and off 2 hours before sunset
Overlap between switch-on and switch-off times
The following geodata applies to the examples below:
l
Latitude: 60
l
Longitude: 0
l
Offset O1 = -4
l
Offset O2 = 4
During the summer months, the switch-on time will overlap with the switch-off time.
This will cause function block output Q1=1 to always remain on during these months.
Fig. 169: Q1 does not switch off during the summer months
Switch-off time before switch-on time
The following geodata applies to the examples below:
l
Latitude: 60
l
Longitude: 0
l
Offset O1 = 5
l
Offset O2 = -7
In the winter months, the switch-off time is before the switch-on time. This will cause
function block output Q1 to always remain off during these months.
