QCA-Z1000 Thermostat

COSYS Building Controls


Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.

The QCA-T1000 adds an MS/TP network sensor option to our line of sensors and thermostats. The QCA-T1000 gives building occupants an intuitive touch-interface to adjust individual comfort levels while tailoring to the needs of their specific market. Featuring a universal input and a standard temperature sensor with humidity, CO2 and motion options, the QCA-T1000 also offers a choice of backlit colors to provide additional user feedback and esthetic appeal.
The T1000 NFC technology allows installers to use NFC-enabled mobile devices to configure the sensor on the wall or in its shipped box.

The QCA-T100 has the same sensing functionality as the QCA-T100 but instead communicates on an MS/TP network that allows easy integration with other Quest or third-party MS/TP networks. The
 QCA-T100 is suitable for a wide range of sensing applications, from basic temperature monitoring, to indoor air quality and occupancy sensing. A customizable interface allows for intuitive user interaction.
The external universal input allows for additional zone monitoring such as window or door contact, external motion sensor for larger rooms, temperature averaging or other local sensor information.
