It has never been easier to install advanced energy efficient central heating control. Honeywell Sundial RF² packs are unique in being the only wireless products with the receiver built into the timer. Each pack includes a wireless enabled timer and a wireless thermostat. Simply replace the timer and the thermostat works automatically, with no additional wiring. Packs for space heating and stored hot water also include a wireless cylinder thermostat.
Installation is quick and easy, with no control cables to run, so no disruption during wiring and no damage to the décor.
The controls and large displays have been very carefully designed to be very easy to use by people of all ages and abilities.
They feature TPI (Time Proportional and Integral) advanced energy saving control, which provides more accurate temperature control than traditional home controls and uniquely also matches boiler firing to system load, so the boiler operates much more efficiently.
The packs provide an ideal solution to providing advanced energy saving control for the 80 percent of UK homes which lack the minimum controls required by Building Regulations in new systems, and the 8½ million lacking even a thermostat. The packs also provide advanced energy saving control for new heating systems.
Three pack types are available to match a heating system’s exact needs. Pack 1 for space heating systems provides the traditional layout of a wireless enabled timeswitch and a separate wireless room thermostat. Pack 2 for systems with space heating and stored hot water has a wireless enabled programmer and a wireless room thermostat. Pack 3 for systems with space heating and stored hot water has a wireless enabled programmer, wireless room thermostat and wireless cylinder thermostat.
The two way RF communication used by Honeywell is extremely robust and reliable. A signal strength test feature allows the installer to site the system components where signal reception is strong.
