Selection of actuators and sensors
Temperature Sensors:
Use only our approved NTC sensors to achieve maximum accuracy. Recommended is SDB-Tn10-20 as Duct sensor, SRA-
Tn10 as Room sensor and SDB-Tn10-20 with AMI-S10 as immersion sensor.
Modulating Actuators:
Choose actuators with an input signal type of 0-10 V DC or 4-20 mA. Minimum and maximum signal limitations may be
set in software.
Floating Actuators:
Actuators with constant running time are recommended. Observe power limits on binary devices.
Binary auxiliary devices:
E.g. pumps, fans, on/off valves, humidifiers, etc. Do not directly connect devices that exceed 48 VAC, 2(1.2) A. Observe
startup current on inductive loads.
