General description
The TCY-BH-U is a stand-alone electronic binary humidity stat. The TCY-BH-U features one internal humidity sensor, one external
NTC temperature sensor input and two binary outputs (Relays).
A detailed parameterization is possible with the use of a simple configuration routine. The TCY-BH-U can be configured using the
standard operation terminal. No special tools or software is required.
Ordering
Selection of devices and sensors
External temperature sensors: Use only our approved NTC sensors to achieve maximum accuracy. Recommended is SDB-Tn1015 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!
