The AR1-H panel humidity controller has been designed for the distributed process control environment with the following user-oriented characteristics:
Panel Hygrostat AR1-H The AR1-H processes our humidity sensor signal in typical applications (without any other components) such as:
  • Direct control of independent cooling and heating circuits,
  • Control of three-way valves,
  • Control of single cooling or heating circuit selected by external command signal, and
  • Hygrostatic/thermostatic control with simultaneous driving of optical/acoustic alarms or timed systems.

The controller features the following resources:

The front panel is protected to IP54 and is covered by a polyester membrane. The display is visible through a suitably transparent window and the switches are of the tactile type.

The AR1-H is parametrically programmable for each output in the following:

All parameters are programmable (separately or in groups) at all times (including during normal operation) via the serial port. This enables the thermostat to be used as a slave to a master which dynamically alters set-points or performs fuzzy control.

The measured temperature and humidity values are the result of internal DSP filtering.

The three bit inputs (of the four) enable control by local hardware. Each output function can be individually reversed (between "Heat"/"Cool" and "Dry"/"Wet") and parameter changes can be enabled. (The fourth input is connected to the humidity sensor).

The hygrostat is automatically detected when in a Quamatic network. In this case, all its data, parameters, settings etc are available on-line in hard real time.
