The innovative Horstmann CentaurPlus ZW combined

wireless room stat and timeswitch offers installers and

householders the opportunity to easily and cost effectively

upgrade existing combi boiler control systems.

There are millions of combi boilers currently installed in the

UK with no room thermostat. The CentaurPlus ZW combined

timeswitch and wireless room thermostat offers a quick,

simple and cost effective solution. Simply replace the

existing timeswitch and install the wire free room

thermostat which will then start to save energy of up to

10%* compared with the installation with no room

thermostat.

The timeswitch features an upgraded back lit display and

incorporates an automatic GMT/BST clock. It uses proven Z

wave wireless technology to communicate with the energy

saving room thermostat that uses the latest TPI energy

saving software.
