HRT4-ZW with ASR-ZW receiver

Wireless Z-wave electronic room thermostat and ASR-ZW receiver with load compensation

• avoids disruptive and time consuming wiring
• compatible with most heating systems.

With proven Z-wave wireless technology using the 868.42MHz operating frequency, the thermostat unit features a constant RF status display with its receiver being mains powered with volt free contacts.

HRT4-B

The HRT4-B is a wired battery operated room thermostat with load compensation – for use with new installations or as a replacement for existing room thermostats.
The HRT4-B has 3 amp volt free change over contacts – making it ideal for use with combi boilers as well as conventional mains operated equipment.
Designed to look good, these thermostats will out perform many older styles of thermostat and can often produce savings in the order of 10% over and above those achieved by traditional units using older technology.
Adjustable settings for Gas, Oil and Electric systems and the display shows 1°C resolution, heating ON symbol, target and actual temperatures at the touch of the dial and an energy saving back light that switches off after 7 seconds. Uses load compensation technology to minimise boiler cycling and reduce flow temperatures.
Available in wireless and wired versions – for new and replacement situations – there is a Horstmann thermostat to suit most installations.
The wireless version employs the latest Z-Wave radio frequency (RF) technology resulting in a highly reliable and trouble free wireless connection with minimal setting up procedures.
Thermostat battery life is in excess of two years using 2 standard AAA batteries which are supplied. A battery low indication tells the user when the batteries need changing.
