Z Wave Room Thermostat with LCD Display by Horstmann

Calculated at checkout

Comes with our own UK Automation easy to follow instructions to get this fully working with Vera and Veralite. Without these you may have difficulty getting it to work correctly. If required select when purchasing.

The Horstmann HRT4-ZW is a battery operated Z-Wave enabled room thermostat. The desired temperature in the room can be set locally using the large dial on the front of the unit. It works in the same way as a normal room thermostat but is not hard wired to the heating source, instead control is achieved using Z-Wave wireless signals between the thermostat and the ASR-ZW receiver unit or a suitable switch attached to the heating source. In parallel suitable z-Wave control software or Z-Wave controller like Veralite or Fibaro Home Center 2 can be used to set the target temperature using Z-Wave. This enables you to control heating times and schedule zone heating. The thermostat itself does not have any internal timers but executes the wireless settings (COMMAND CLASS THERMOSTAT_SETPOINT) and the local setup.

  1. Awesome product

    Posted by Rosa on 6th Aug 2013

    I set this up with my razberry (a raspberry pi zwave gpio card) and it works very well.

    I had a really old boiler and I had to add a little wire between L and 2 as this diagram http://i.imgur.com/TZ8AmVS.png

    Overall it works great and could not be happier. Good range, easily replaced existing thermostat.
