While Greenstar gas boilers are energy-efficient, you can increase the performance of a unit by using a good boiler control. Besides, when you buy the Worcester DT20RF on eBay, you have complete freedom in heating your home. The Worcester DT20RF digital RF thermostat with twin channel programmer offers compatibility with all Greenstar combination boilers. You can also use it with Greenstar system boilers as long as you also use the optional integral diverter valve.
It offers three separate time periods to control hot water and three time periods to control central heating. This can vary every day of the week, and you can also set a target temperature that remains the same throughout. Communication between transmitter and receiver relies on wireless radio frequency, so you do not have to worry about installing extra wiring. This unit includes a ?holiday function? that overrides existing settings and suspends heating for a given time period. Do not worry about manually changing your home?s heating settings anymore; this control will do it for you automatically.
