The influence of current room temperature on calculation of the flowtemperature setpoint can be adjusted in the menu “Heating circuit – function – roominfluence“.Contacts / counter17Sensor groundSensor NN1618 Sensor L 1519 Sensor Potential for 13 1420 Sensor Relay 1321 Sensor Not used 1222 Sensor Relay 1123 Sensor Potential for 9+11 1024 Sensor Relay 925 Contact / counter Not usedPE826 Contact / counter Relay 727 0…10 V Potential for 5+7 628 0…10 V Relay 529 Sensor ground Not used 430 Not used Relay 331 Not used Potential for 1+3 232 Not used Relay 1Fig. 2.8: Connection of counters, contact inputsA signal can consist of a feedback signal from a pump or a ventilator. The wires haveto be connected to the assigned terminal and the sensor ground. Terminal 25 or 26may be used either as a signal input or a counter input.°CSPComponentsending signalor pulse
