CentaurPlus ZW and HRT4-ZW  

Installation Instructions

The Horstmann CentaurPlus ZW combined wireless room stat and timeswitch 
allows a combi boiler system to have a room thermostat added without the 
need for any additional wiring.

Replacing the existing timeswitch with the CentaurPlus ZW will allow the room 
thermostat to be connected wirelessly producing immediate energy savings in 
houses where no previous room thermostat has been fitted.

The device is intended to upgrade existing combi boiler systems that do not 
have an existing room thermostat. It is not intended for new installations where 
it will be necessary to install two heating zones in order to comply with current 
Building Regulations.
