    • Picture 1. Press HVAC button to enter HVAC menu

    • Picture 2. You entered HVAC Menu

    • Picture 2. Use Home button to return to Home Screen

    • Picture 2. Use Up button to return to Advanced Menu

    • Picture 2. Use Next and Prev button to navigate through various settings

  3. System type setting is used to define controlled system type:
    • System type setting is used to define controlled system type:

    • Ventilation - only air flow is controlled manually or automatically by CO2 and/or relative humidity sensor. Analog output 1 (AO1) will control VAV through 0-10V signal

    • Ventilation & cooling same as ventilation but also allows Temperature control as cooling function.

    • Cooling function turns on outputs only when Setpoint is lower then the current Temperature, thus cooling the room

    • Ventilation & heating same as ventilation but also allows Temperature control as heating function

    • Heating function turns on outputs only when Setpoint is higher then the current Temperature, thus heating the room

    • Ventilation & heat or cool same as ventilation but also allows Temperature control as cooling or heating function. Choice between Heating or Cooling is either manual in Menu (link) or by external RTD sensor if set up in InOut Menu (link)

    • Ventilation & heat & cool same as ventilation but also allows Temperature control as cooling and heating function. Heating and cooling function automatically turns on heating or cooling depending on the current setpoint and temperature

  4. Select VAV controlled by to determine which sensor shall influence turning on VAV output
    • Select VAV controlled by to determine which sensor shall influence turning on VAV output

    • PPM - VAV is turned on if the PPM value is higher then the Setpoint for PPM

    • %rH - VAV is turned on if the rH value is higher then the Setpoint for rH

    • Temp - VAV is turned on if the Temp value is higher then the Setpoint for Temperature

    • If System type is Ventilation, then Temp can not be chosen

    • Combinations of multiple of these elements are also possible

    • Manual - VAV is controlled manually by Air flow MAX, MID, MIN options on the Home Screen(link) defined by Air flow setpoints in Setpoint Menu (link)

  5. Humidity control allows outputs to be turned on by humidity values
    • Humidity control allows outputs to be turned on by humidity values

    • There are separate control options for:

    • Summer

    • Winter

    • Press the Enabled/Disabled button to toggle options for each control

  6. Adjust settings for PI controller for Temp, CO2 and Relative Humidity
    • Adjust settings for PI controller for Temp, CO2 and Relative Humidity

    • Adjust P-band and I-time for each PI controller

    • P-band determines the speed of change. Higher number = faster change, but more volatile

    • I-time determines the slowness of change. Higher number = slower change, but more accurate with less overshoot

    • Use + and - buttons to increase values by 0.1

    • Press value button to enter Keyboard to input number

    • Press Save to confirm changes

  7. Adjust settings for PI controller for Valve / Heater
    • Adjust settings for PI controller for Valve / Heater

    • Adjust P-band and I-time for each PI controller

    • P-band determines the speed of change. Higher number = faster change, but more volatile

    • I-time determines the slowness of change. Higher number = slower change, but more accurate with less overshoot

    • Use + and - buttons to increase values by 0.1

    • Press value button to enter Keyboard to input number

    • Press Wall type button and select the type of wall Codis is mounted on to fine tune temperature measurement

    • Press Save to confirm changes
