Selection of devices and sensors
External temperature sensors: Use only our approved NTC sensors to achieve maximum accuracy. Recommended is SDB-
Tn10-15 as Duct sensor and SOA-Tn10 as outdoor sensor.
Binary auxiliary devices: E.g. humidifiers, de-humidifiers and fans. Do not directly connect devices that exceed 2(1.2)A.
Observe startup current on inductive loads!
