    Beskrivelse:

    Designed to control room humidity

    Functions:

    - Relay- and proportional control (0-10 Volt or 0-20 mA)
    - Bandwith adjustment
    - Led bar readout of proportional control
    - Digital readout of setpoint and rH
    - Membrane keypad
    - Led indicators for humidification and de-humidification
    - Led indicators for humidification and de-humidification relay on

    Proportional and relay control

    The Hygrozone has proportional controls. Humidification and de-humidification are then controlled by a 0 to 10 Volt signal. This means that if rH = setpoint, both outputs are 0 Volt (humidification and de-humidification).

    Humidification

    If rH is less than setpoint, the Hygrozone-output for humidification will increase to 10 Volts. Thissignal can be connected directly to the Contronics humidifiers for proportional control. If this difference of setpoint minus rH exceeds the adjusted bandwith (between 1% and 10%) the humidification relay will switch on. The hygrozone offers the choice of proportional or on/off control or both in case extra humidification is required.

    De-humidification

    If rH is greater than setpoint, the Hygrozone-output for de-humidification will increase to 10 Volts. This signal can be connected directly to a de-humidifier for a proportional control. If this difference rH minus setpoint exceeds the adjusted bandwith set (between 1% and 10%) the de-humidification relay will switch on. In this case the Hygrozone again offers the choice of proportional or on/off control or both.
