The new Horstmann Controls’ HRT4-ZW wireless room thermostat for domestic central heating applications features two of the very latest control and communications technologies.
HRT4-ZW is an electronic battery powered room thermostat that uses interoperable two-way Z-Wave™ RF mesh networking technology to provide optimum comfort. This proven technology is highly reliable and permits easy network management.
Z-Wave not only offers close control of the energy used to heat the home but removes the need for additional wiring or unsightly cable runs. This substantially reduces installation times and the disruptions and décor damage associated with hard wiring.
The ‘stat also features the latest TPI (Time Proportional Integral) control software that outperforms many older styles of thermostat creating the potential for energy savings in the order of 10%. A TPI regulating thermostat will maintain the comfort level far more efficiently than any traditional thermostat and when used with a condensing boiler, the ‘stat will help to save energy as the control algorithm allows the boiler to operate in condensing mode more consistently in comparison with older types of traditional thermostat.
Thermostats using TPI control algorithms also reduce the temperature swing that normally occurs when using bellows or thermally operated thermostats.
The HRT casing designs are finished in a white/pale blue colour combination and features (on relevant models) include a clear backlit LCD display, easily recognised symbols, and a two year battery life.
Designed to complement Horstmann’s extensive range of programmers, controllers and zone valves, the HRT series offers 5 versions of the ‘stat, covering not only the RF but wired with mains or battery powered options and more specialist Frost Stat and Tamperproof models.
The units have been designed by the same team who developed Horstmann’s ChannelPlus, CentaurPlus and ThermoPlus central heating programmers and in combination will provide the householder with a state-of-the-art heating control solution.
