GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM ROOM HUMIDITY TRANSMITTER HRC SERIES PRODUCT DESCRIPTION The HRC series room humidity transmitter uses a highly accurate and field-proven RH sensor in an attractive low profile enclosure to monitor room relative humidity levels. Additional options include an occupancy override button, a slide-pot setpoint control, a resistive temperature sensor and an LCD display. The RH output can be field selected as a linear 4-20 mA or 0-5 / 0-10 Vdc signal. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The HRC series can be mounted directly to a single gang electrical box or directly to a wall. Multiple mounting holes are provided for connection to a variety of electrical boxes. A terminal block connection is provided for connection to the Building Automation System.
