Cut costs and save energy with Honeywell's wireless solution.
As 84% of domestic energy is used for heating and hot water, simply upgrading existing heating controls with Honeywell wireless Sundial RF2 packs is an easy, cost-effective way to save energy and cut fuel bills, says the company.

Their time proportional and integral (TPI) energy-saving control provides more accurate temperature control than traditional controls and matches boiler firing to the demands for heat from the heating system for greater efficiency.
