GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM ROOM TEMPERATURE TRANSMITTER TXRC SERIES PRODUCT DESCRIPTION The TXRC series room temperature transmitter is an attractive, low profile enclosure that incorporates a precision platinum RTD and a transmitter that provides a high accuracy signal with excellent long term stability, low hysteresis and fast response for measurement of room temperatures. Additional options are available which include setpoint adjustment, manual override & Fan speed control. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The TXRC series can be mounted directly to a single gang electrical box or directly to a wall. Insulating foam is adhered to the back of the enclosure to provide a thermal barrier from internal wall temperatures. A terminal block connection is provided for connection to the Building Automation System.
