A controller with pre-set standard applications and free programming, suitable for relevant and appropriate process types, PI, Or PID mode • menu selection operation is used for ventilation, air conditioning, and refrigeration process equipment ranging from basic to complex. A universal controller is used to handle the following control variables: temperature, relative/absolute humidity, pressure/differential pressure, gas flow rate, indoor air quality, and enthalpy. Select operating mode through status input: Comfort, Economy, Protection • Display current operating mode (Comfort, Economy, Protection) • With respective sequential controllers: individually adjustable heating and cooling setpoints (or maximum and minimum setpoints) for comfort and economy modes • Pre defined room temperature setpoints through indoor operating units or setpoint adjusters (passive) • For various sequential controllers: adjust remote setpoints (active or passive) Pre defined setpoints • Room temperature setpoints with summer and/or winter compensation • For various sequential controllers: Setpoint offset depends on sensor signals, optional starting and ending points Universal input: • Passive or active analog input signals for different measurement values( ° C,%, ---) • Digital input signal (no voltage dry node) • Universal controller (sequence controller) for two heating sequences (reverse action) and two cooling sequences (forward action) can be used as a P -, PI or PID mode controllers can also be used as differential controllers. The controller can be configured as an indoor/supply air temperature cascade controller, while limiting the supply air temperature Each sequence can be specified as regulating output control (regulating output, stepper switch, mixing air door, heat recovery equipment) and pump. Two sequences can simultaneously apply to the same regulation output control (such as priority cooling/dehumidification) • General limiting function (each sequence controller forms a maximum/minimum function in PI mode), which can be used for absolute limiting (such as supply air temperature or supply air humidity) or relative temperature limiting (such as indoor/supply air temperature difference). The restriction applies to all orders. When the cooling is turned on (such as using a direct expansion refrigeration coil), a lower limit can be set for the lower set point Each sequence controller uses the PI mode sequence control function, which can be defined as a lower or upper limit. Restrictions apply to a single sequence (such as the upper limit of the return water temperature of heat recovery antifreeze or air heating coil) The mixed air temperature control can be controlled by the air door to regulate the temperature of the mixed air in a single sequence Digital input (heating limit switch of a heating controller), used to change the control strategy (indoor/supply air cascade/supply air), and can be set
