CPD Hours

Key Areas

  • Concentrating on achieving the deliverable rather than explaining control theory
  • What are we trying to achieve?
  • How do we control different systems - How do we make them do what we want?
  • What equipment is used and how does it work?

Course Content

Session 1: Heating & Hot Water Systems

  • Boilers. Single v Modular. Step control. Primary circuit control.
  • Constant temperature and compensated temperature control.
  • Pressureless headers, TRVs 2 & 3 way valves (on/off, mixing v diverting).
  • Provision of thermostatic control. Building Regulations requirements.
  • Time, temp and interlock with boiler pump. Desirable temperatures.
  • Pumped secondary, monitoring of stored water temperatures to minimise risk of legionella.

Session 2: Mechanical Ventilation & Air ConSystems

  • How different systems work
    • dew point stat
    • reset for minimum zone requirement
    • local reheat VAV fan speed control
    • Ch W controls.
  • Return temperature sensing.
  • Compressor, Condenser and Evaporator controls.
  • Compressor capacity controls.
  • Heat pumps - reverse cycle

Session 3: Cooling & Refrigeration Systems

  • Chilled water control for different systems.
  • Dew point control. Chiller temperature and capacity control.
  • Heat recovery. Control of different compressors.
  • Air and water-cooled condensors. Storage systems. Thermosyphons.

Session 4: Sensors and BEMS

  • A review of the control hardware used.
  • Appropriate control: Review of Building and Energy Management Systems - their advantages and disadvantages

Learning Outcomes

  • Understanding the principles of control operation
  • Practical insight to control components that are used
  • Understanding how different systems are required to work to meet performance requirements
  • Selection of control valves
  • Developing a critical approach to control system specification, especially BEMS.
