Model 2500: Network Humistat
Datasheet
Description
The
Model 2500 Network Humistat is a standalone de-humidifier controller.
It contains a temperature sensor, humidity sensor, microprocessor,
measurement electronics, and an optional network communication interface.
The external de-humidifier is controlled via an on-board relay.
The relay has a rating of 10 Amps at 110 or 220 VAC.
The temperature and humidity
sensors are in a porous filter, away from the electronics.
This allows a more accurate measurement of air temperature and humidity
for two reasons. One, it isolates
the sensors from temperature generated by the electronics.
Two, it provides excellent airflow around the sensors.
The sensor and configuration
information is communicated to other devices via the LonWorks communication
protocol. This allows multiple
sensors to be used over a simple four-wire bus installation.
