GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

HIGH ACCURACY HUMIDITY / TEMPERATURE TRANSMITTER C/W SETPOINT ADJUSTMENTS

HASPC SERIES

PRODUCT DESCRIPTION

The HASPC series uses a highly accurate and reliable

thermoset polymer based capacitance humidity sensor

and curve matched thermistor together with state-of-the-

art digital linearization and temperature compensated

circuitry in an attractive, low profile enclosure to monitor

room humidity & temperature levels. Dual setpoint

adjustment features for both RH and temperature are also

available. Additional options include manual override

TYPICAL INSTALLATION

For complete installation and wiring details, please

refer to the product installation instructions.

The HASPC 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.
