Additional settings:
● Differential pressure control using the technology controller
● Technological unit: p0595 = 1 (%), reference variable: p0596 = 1
● Default setting of the technology controller:
– Enable: p2200 = 1
– Fixed value 1: p2201 = 50 %
– Ramp-up/down time for setpoint: p2257 = p2258 = 30 s
– Ramp-up/down time for controller output: p2293 = 30 s
– Upper and lower limits, actual value: p2267 = 120 %, p2268 = -10 %
– Actual value filter time constant: p2265 = 10 s
– Proportional gain K
