General description

The TCY-BH is a stand-alone electronic binary humidity stat. The TCY-BH 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 can be configured
using the standard operation terminal. No special tools or software is required.

Technical specification

Important notice and safety advice

This device is for use as operating controls. It is not a safety device! Where a device failure endangers human life
and/or property, it is the responsibility of the client, installer and system designer to add additional safety devices to
prevent a system failure caused by such a device failure. Ignoring specifications and local regulations may cause
equipment damage and endangers life and property. Tampering with the device and misapplication will void warranty.

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!
