  abstract

  Quote: "The overall aim of this study was to collect, analyse and synthesise available evidence on weather compensation, load compensation and Time Proportional and Integral (TPI) heating controls, as applied to domestic boilers (fuelled by gas, oil and LPG). ... rough estimates based on stakeholder responses suggest that the current market shares are around 12% for TPI control, and around 2% for both weather and load compensation."
  note

  [Quote: "The definitions of these ErP (Energy related Products) control type can be summarised as follows: Class I represents standard on/off temperature controller which would be sufficient to meet with Building Regulation requirements. Class II and Class III are weather compensating controls, for modulating boilers and on/off boilers, respectively. These are not prevalent in the UK compared to other European countries as they do not include a room thermostat. The amount of heat supplied by these controls is determined solely by the external temperature sensor. Class IV is a TPI temperature controller for use with an on/off boiler. Class V is a load compensating controller. Class VI is a weather compensation controller for use with modulating boilers with a room thermostat, whilst Class VII is a variant that uses time proportion control to facilitate control of the boiler output temperature by switching the boiler on or off rather than modulating the output. Finally Class VIII is a more sophisticated form of load compensating controller where the boiler flow temperature is determined by the aggregated heat load determined from multiple room thermostats."]
