Combined wireless room stat and timeswitch
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.

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.
