GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM HUMIDITY / TEMPERATURE TRANSMITTER C/W SETPOINT ADJUSTMENTS SPC SERIES PRODUCT DESCRIPTION The SPC Temperature/Humidity transmitter incorporates two sensors in one attractive wall mount enclosure for the most efficient environmental monitoring and control system. It uses a field-proven RH senor to monitor relative humidity and a curve-matched thermistor to measure temperature. Two setpoint controls are also available for temperature and humidity adjustment. The device may also include an occupancy override button. Both measurements and setpoint signals are available on separate outputs as linear 4-20 mA, 0-5 or 0-10 Vdc signals. Several configurations of the device are available with one to four outputs as required. An LCD is included for configuration and local indication of all parameters. Several operating parameters can be programmed using a keypad for specific applications including four temperature ranges and °C / °F display. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The SPC series can be mounted directly to a single gang electrical box or directly to a wall. Insulation foam is adhered to the back of the enclosure to provide a thermal barrier from wall temperatures. A terminal block connection is provided for connection to the Building Automation System.
