Horstmann HRT4 Z-wave enabled thermostat that can fully replace classic thermostat. Installing this device will allow you to control your heating and cooling system using Zipato advanced scheduling automation as well as remote control. The HRT4-ZW is a battery operated wall thermostat. Using a big wheel on the device the user can preset the desired target temperature in the room. By verifying the target temperature with the measured real temperature closed to the device the unit decides how to operate a wirelessly attached power switch that is attached to the heater. In parallel a central gateway of z-Wave control software can set the target temperature using Z-Wave. This enables to realize a time scheduled zone heating. The thermostat itself does not have any internal timers but executes the wireless settings (COMMAND CLASS THERMOSTAT_SETPOINT) and the local setup.
