Control equipment Connection descriptions lindab | we simplify construction Regula Combi 1.5 10 11 12-14 G+ Supply voltage 24 V AC G0- Supply voltage 0 V No function. 20 GDO 24 V AC out common for DO. Internally connected to terminal 10, G+. 21 G0 0 V common for UO. Internally connected to terminal 11, G0-. 22 UO3 Control output forcing (cooling). For a 0-10 V DC actuator, max 5 mA. The actuator’s 0-10 V control signal terminal is connected to terminal 22 and its supply terminals to terminals 20 and 21. Make sure that the reference pole G0- is connected to the correct terminal on the actua- tor. Alternatively for a 24 V AC thermal actuator, max 2.0 A. The thermal actuator is connected between terminals 22 and 20, GDO. 23 UO1 Control output heating. For a 0-10 V DC actuator, max 5 mA. The actuator’s 0-10 V control signal terminal is connected to terminal 23 and its supply terminals to terminals 20 and 21. Make sure that the reference pole G0 is connected to the correct terminal on the actuator. Alternatively for a 24 V AC thermal actuator, max 2.0 A. The thermal actuator is connected between terminals 23 and 20, GDO. 24 UO2 Control output cooling. For a 0-10 V DC actuator, max 5 mA. The actuator’s 0-10 V control signal terminal is connected to terminal 24 and its supply terminals to terminals 20 and 21. Make sure that the reference pole G0- is connected to the correct terminal on the actua- tor. Alternatively for a 24 V AC thermal actuator, max 2.0 A. The thermal actuator is connected between terminals 24 and 20, GDO. 30 AI1 For temperature sensor, PT1000. Measuring range 0-50 °C. The sensor is connected between terminals 30 and 41, AGnd. 31 AI2 For a 0-10 V CO 2 sensor. Alternatively for a 0-10 V Damper position. The sensor is con- nected between terminals 31 and 41, AGnd. 32 DI1 Presence sensor. A potential-free contact is connected between terminals 32 and 40, +C. Alternatively for a Window contact. 33 DI2/CI Condensation detector. The sensor is connected between terminals 33 and 41, AGnd. Alternatively for a Change Over indicator, CO 2 Relay sensor or CO 2 Pulse sensor. 40 +C 24 V DC out common for DI 41 AGnd Analogue ground, reference for AI1 and AI2 42 A RS485-communication A 43 B RS485-communication B Analogue and digital inputs If changing the setting for an analogue or digital input (AI1, AI2, DI1 or DI2), it is recommended to take the Regula Combi out of its console, making it powerless for a moment.
