G, G0 Operating voltage AC 24 V (RDG160KN)
L Feed for relays AC 24...230 V (RDG160KN)
X1, X2 Multifunctional input for temperature sensor
(e.g. QAH11.1) or potential-free switch
Factory setting:
– X1 = External temperature sensor
– X2 = No function
(function can be selected via parameters P38 / P40).
M Measuring neutral for sensors and switches
D1, GND Multifunctional input for potential-free switch
Factory setting: Operating mode switchover contact
(function can be selected via parameter P42).
Q1 Control output fan speed "low" AC 230 V
Q2 Control output fan speed "medium" AC 230 V
Q3 Control output fan speed "high" AC 230 V
Q1...Q3 Also for special functions AC 24...230 V (RDG160KN)
Y1…Y4 Control outputs "Valve" AC 230 V (RDG100KN)
("N/O" triac, for normally closed valves),
output for electric heater via external relay
Y10, Y20 Control outputs "Valve" DC 0...10 V (RDG160KN)
Y50 Control output "Fan" DC 0...10 V (RDG160KN)
