ATAG OneZone Hot Water Priority Kit
ATAG OneZone Hot Water Priority Kit
Featuring the legendary OneZone intelligent modulating controller, the ATAG OneZone Hot Water Priority Kit automatically manages the separation of heating and hot water circuits for System and Heat Only boiler installations. The system allows different flow temperatures to be set for heating and hot water with a motorised valve to switch between space heating and DHW. By increasing the hot water heating flow temp, this speeds up the hot water production times providing homeowners with ample hot water on tap.
When in space heating mode the kit drops the flow temperature to maximise condensing and boost efficiency.
The homeowner benefits from increased comfort and lower fuel bills. It’s a no-brainer for most System and Heat Only installs.
Everything you need is included in the kit, The OneZone controller, motorised valve connections including NTC cable and instructions including wiring diagrams.
And don’t forget – purchase the ATAG OneZone HWPK with a regular or system boiler and your warranty will be upgraded to 18 years.
