84% of domestic energy consumption is used up in heating and hot water, producing 70% of domestic carbon emissions so controlling heating is very important.

If you turn your thermostat down by just 1º, this alone will reduce your energy consumption by 10%, having more effect than turning off all your light bulbs and never using them again.

The Sundial RF2 Packs have optional features called Optimisation which aim to make you as warm and as comfortable as possible, whilst also saving energy. Optimisation only applies to your heating, not your hot water.

Optimum Start

The controls can be set to work out when to come on, to suit when you want to be warm.  Each day the boiler will start at the latest possible moment depending on the weather.

Delayed Start

Once your earliest start time has been programmed, the controls will delay the boiler firing times on warmer days, when it is possible to save energy.

Optimum Stop

The controls will switch your boiler off before the normal programme time whenever possible – saving you energy and money.

TPI Control

Time proportional and Integral (TPI) control is a way of calculating the demand of a room thermostat, controlling your boiler so that it fires for shorter periods as the temperature approaches the set point. Savings of up to 10% of energy consumption can be achieved.
