GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM ROOM HUMIDITY TRANSMITTER RH100B SERIES PRODUCT DESCRIPTION The RH100B series uses a highly accurate and reliable Thermoset Polymer based capacitance humidity sensor and state-of-the-art digital linearization and temperature compensated circuitry in an attractive, low profile enclosure to monitor room humidity levels. An optional temperature sensor is available. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The RH100B sensor installs directly on a standard electrical box and should be mounted five feet from the floor of the area to be controlled. Do not mount the sensor near doors, opening windows, supply air diffusers or other known air disturbances. Avoid areas where the sensor is exposed to vibrations or rapid temperature changes. A terminal is provided for connection to the Building Automation System.
