描述

Use

For use on basic to complex ventilation, air conditioning and chilled water plant. The universal controllers are designed to handle the following controlled variables: Temperature, relative/absolute humidity, pressure/differential pressure, airflow, indoor air quality and enthalpy.

Operating modes

  • Selection of operating mode via status inputs: Comfort, Economy, Protection
  • Display of current operating mode (Comfort, Economy, Protection)

Setpoints

  • With each sequence controller: Individually adjustable heating and cooling setpoints (or maximum and minimum setpoints) for the Comfort and Economy modes
  • Predefined room temperature setpoint with room unit or setpoint readjuster(passive)
  • With each sequence controller: Predefined setpoint with remote setpoint adjuster(active or passive)
  • Room temperature setpoint with summer and/or winter compensation
  • With each sequence controller: Setpoint shift depending on sensor signal, selectable start and end points

Universal input

  • Universal inputs for:
  • Passive or active analog input signals of various measured values (°C, %, —)
  • Digital input signals (potential-free contacts)

Control Functions

  • Universal controller (sequence controller) for 2 heating sequences (reverse acting) and 2 cooling sequences (direct acting), can be used as a controller providing P-, PI or PID mode, or as a differential controller
  • Controller can be configured as a room/supply air temperature cascade controller with limitation of the supply air temperature
  • Each sequence can be assigned modulating control (modulating output, step switch, mixed air damper/heat recovery equipment) and a pump. 2 sequences can act on the same modulating control (e.g. priority cooling/dehumidification)
  • General limitation (minimum/maximum with PI mode per sequence controller, either as absolute limitation, e.g. for the supply air temperature or supply air humidity), or as relative temperature limitation (e.g. maximum limitation of the
    room/supply air temperature differential). Limitation acts on all sequences. Minimum limitation can be set to a lower setpoint while cooling is on (e.g cooling with DX cooler battery)
  • Sequence limitation with PI mode per universal controller, can be defined as minimum or maximum limitation. Limitation acts on a single sequence (e.g. heat recovery anti-icing protection or maximum limitation of the heating coil’s return
    temperature)
  • The mixed air temperature controller controls the mixed air temperature via the air dampers
  • Locking of individual sequences
  • Digital input (heating limit switch, from a heating controller) for changing the control strategy (room-supply air temperature cascade control), configurable
