Microprocessor controlled units have an easy-to-read multi-lingual interface, which shows operational status and makes commissioning simple. Set point, ambient humidity and temperature, purge and flush cycle operation, hours run, service interval times, occupancy operation and fault diagnostics are shown. The display can be installed up to 100m away from the control panel.
For improved control in large areas, up to three averaging humidity sensors can be connected to the microprocessor controller or it can be linked to a building management system. On/off and modulating control is available on high capacity systems allowing ±2%rH control. Modulating systems also incorporate information on water flow.
