    Control Strategy for AHU OT Room

    Hi,

    I'm got some question regarding to Operation Theater (OT) Room control strategy.

    Is it possible this control strategy :-

    Room Humidity - Control by other controller ( standlone DDC ) another brand

    The humidifier is control by ON/OFF not ( 0-10V/0-5V/ 4mA-20mA)


    Room Temperature - Control by other controller.

    For future, is it Humidity and Temperature can achieve the setpoint.

    Please help me if anyonne have experience working with OT Room

    Can you be more specific with your question...How many controllers are involved? Are they able to share information between them? what is your role in this equation? etc...

    Sir,
    Only 2 DDC involve in this OT Room. Both DDC cannot share information to each other. One DDC control the heater to maintain Humidity and the other DDC control the Valve to maintain the temperature setpoint.

    From my experience, the humidity of the room should be control by valve and the room temperature control by heater. Correct me if i wrong.
