Heatit Z-Water 2 is a DIN rail controller for controlling water-based heating systems. The module is clamped directly onto a DIN rail and allows you to control your water-based heating system via your Z-Wave network. Heatit Z-Water 2 is equipped with 9 potential-free relays for actuators. It also has 2 analogue inputs for temperature sensors.

The Heatit Z-Water 2 relays can be controlled by associations with other Z-Wave thermostats, e.g. Heatit. Each relay can control one or more actuators in your heating system.

Introducing Z-Wave Plus™
Z-Wave Plus™ is a new level within Z-Wave certification and is designed to help consumers identify those products that utilise the “GEN5” Z-Wave hardware platform (also known as 500 series or 5th generation Z-Wave chips). Generation Z-Wave chips). Z-Wave Plus certified products have several advantages that increase ease of use and make Z-Wave solutions even faster and easier to install and set up.

Since the certification of the first Z-Wave product in 2004, Z-Wave has become the market leader for interoperable smart devices in home networking. With the introduction of the new Z-Wave 500 series, the Z-Wave ecosystem has been expanded with new features – such as increased range, longer battery life, Over The Air upgrades (OTA), and additional RF channels.

products with Z-Wave Plus™ are fully backwards compatible with existing Z-Wave products!

For consumers, homeowners, integrators and service providers, the Z-Wave Plus™ enhancements offer tremendous benefits in terms of shorter and easier installations, more extensive device profiles, improved self-healing and longer battery life. With the new Z-Wave Plus certification programme, the Z-Wave Alliance is also introducing a series of logos that can be found on the packaging of Z-Wave Plus™ certified products, informing consumers of the benefits of the Z-Wave 500 series.

Benefits
– 50% improvement in battery life
– 67% improvement in range
– 250% increase in bandwidth
– Three RF channels for improved noise immunity and higher bandwidth
– New network-wide plug-and-play inclusion feature
– Improved self-healing and fault tolerance Improved self-healing and fault tolerance with explorer frame function
– Standardised procedure for over-the-air firmware updates (OTA)
– Improved product information collection for the product certification database

Z-WaveS2
The foundation of S2 is all everything needed for a smart home: The latest version of Z-Wave, reduction in power consumption compared to older Z-Wave devices and wireless communication. S2 takes all this and expands the Z-Wave world with:

– Advanced encryption (AES 128-bit)
– More security against hacker attacks
– Improved battery life
– Faster communication between devices
