Heatit Z-Water is a DIN-rail regulator for controlling hydronic heating. The module clips right onto a DIN-rail to add a variety of functions to your wireless Z-Wave network. Heatit Z-Water is equipped with 10 relay outputs and it has 4 analog inputs. The module is power supplied from a 230V AC mains connection and is able to deliver an output supply of 24V DC or 230V.

Heatit Z-Water relay outputs may be freely controlled from the Z-Wave network, and may be used for several purposes, e.g. on/ off control of lights, controlling valve actuators in an underfloor heating system, or controlling other home automation systems.

Heatit Z-Water inputs are analog inputs for interfacing simple temperature sensors; NTC, PT1000, etc.

It is possible to configure the level and the indication of the status indicator LED in the front of the Heatit Z-Water regulator.
