Controls

Central heating controls play an important part in a heating system. Controls provide a homeowner with flexibility as they allow you to have the boiler on at different times of the day, at different temperatures, with modern controls even automatically sensing the temperature and adjusting the boiler operation to provide the ultimate comfort in home heating.

As well as providing greater flexibility and comfort, they play an important part in energy saving. For the relatively low additional investment when upgrading a boiler and central heating system, controls can save up to 10% of a homeowners energy usage.

 It’s Time to Take Control

The new Vokèra controls course can help you understand the principles of combustion and the fundamentals of how control technology can work in conjunction with boiler operation. Additionally the course covers how and when to incorporate these technologies into existing and new heating systems and how you can use this knowledge to help your customers reduce fuel usage.

 Choosing the Right Control

How can controls improve the ErP efficiency rating?

Differing types of controls are classified according to the ‘uplift’ in efficiency it brings to the package. There are eight classes of control system, each adds an efficiency percentage to the boiler seasonal space heating ErP efficiency rating. That is how the package efficiency is calculated. Additional heaters such as a second boiler, heat pump or solar input will also adjust the package efficiency:

Class I: Room Thermostat: A room thermostat that controls the on/off operation of a heater. Performance parameters, including switching differential and room temperature control accuracy are determined by the thermostat’s mechanical.

Class II: Weather compensator control, for use with modulating heaters: A heater flow temperature control that varies the set point of the flow temperature of water leaving the heater dependent upon prevailing outside temperature and selected weather compensation curve. Control is achieved by modulating the output of the heater.

Class III: Weather compensator control, for use with on/off output heaters: A heater flow temperature control that varies the set point of the flow temperature of water leaving the heater dependent upon prevailing outside temperature and selected weather compensation curve. Heater flow temperature is varied by controlling the on/off operation of the heater.

Class IV: TPI room thermostat, for use with on/off output heaters: An electronic room thermostat that controls both thermostat cycle rate and in-cycle on/off ratio of the heater proportional to room temperature. TPI control strategy reduces mean water temperature, improves room temperature control accuracy and enhances system efficiency.

Class V: Modulating room thermostat, for use with modulating heaters: An electronic room thermostat that varies the flow temperature of the water leaving the heater dependent upon measured room temperature deviation from room thermostat set point. Control is achieved by modulating the output of the heater.

Class VI: Weather compensator and room sensor, for use with modulating heaters: A heater flow temperature control that varies the flow temperature of water leaving the heater dependent upon prevailing outside temperature and selected weather compensation curve. A room temperature sensor monitors room temperature and adjusts the compensation curve parallel displacement to improve room comfort. Control is achieved by modulating the output of the heater.

Class VII: Weather compensator and room sensor, for use with on/off output heaters: A heater flow temperature control that varies the flow temperature of water leaving the heater dependent upon prevailing outside temperature and adjusts the compensation curve parallel displacement to improve room comfort. Heater flow temperature is varied by controlling the on/off operation of the heater.

Class VIII: Multi-sensor room temperature control, for use with modulating heaters: An electronic control, equipped with 3 or more room sensors that varies the flow temperature of the water leaving the heater dependent upon the aggregated measured room temperature deviation from room sensor set points. Control is achieved by modulating the output of the heater.

Unica i32 plus Class VI controls (Vokèra 711 RF programmable thermostat plus weather compensation sensor) achieves an ErP A+ (98%) space heating package rating.
