Heatit Z-Wave Thermostat

The Heatit Z-Wave is an electronic thermostat for floor heating in a standard wall box. The thermostat has a built-in Z-Wave chip that can be connected with Home Automation systems.

Heatit Z-Wave is equipped with a single pole switch and fits into most System 55 frames (Elko RS16, Schneider Exxact, Gira, Jung etc.) The thermostat can withstand a load of max 16A / 3600W at 230V. At higher loads the thermostat must control a contactor. The thermostat may be connected to two wired external sensors.

The thermostat has the capacity of up to 8 associations (relays, wall plugs etc.)

The thermostat is designed for electrical heating and does not work together with Heatit Z-Water (45 124 75).


This Heatit device is certified by Pepper One Gmbh according to the requirements set forward by the Z-Wave Alliance and Silicon Labs. This is a Z-Wave Plus product with the 500 series chip. If the product does not work with your gateway, then the gateway manufacturer has not made an integration for such a device. We do not give any guarantee towards integration.


Due to the fact that many of our thermostats are available in both white and black, you may combine frames and fronts as you please. Choose a black frame with a white front (or the other way around) for an edgy look, or go for the traditional all-white or all-black.

FAQ Heatit Z-Wave Thermostat

I know that there is an option to attach two external temperature sensors, but is there also an on-board integrated temp-sensor available?

Yes, there is.

Do I need an external sensor, or does the thermostat also work without one?

The thermostat will work without an external sensor – but it will use the readings from the on-board sensor to determine the temperature of the equipment it controls. If you are interested in reading the exact measured temperature, an external sensor will be more accurate. The internal sensor will be sufficient for 95% of the users.

Is there any LED or display icon signalling that the Thermostat is currently heating - a kind of on/off or heating indicator on the display?

Yes, there is a small Bi-LED with a red light when the thermostat is pulling load. This diode can be found in the right hand corner, directly below the numbers on the display. Once the load on the thermostat is activated, you will hear a clicking sound when the relay kicks in. At the same time, the LED will light up.

Is it possible to change the set-temperature via Z-Wave, to overwrite the manually entered one?

Yes it is. Bi-directional control is enabled. (Use any supported gateway for this).

If I manually change the set-temperature by using the buttons on the Thermostat, how long will this change be valid / in use?

The manually set value will be active until you make a new set-point. If you use a gateway, it will be in use until the next scheduled temperature setting is activated.

Is the Heatit Z-Wave thermostat available in the US or in Canada?

The Heatit thermostat is not for sale on the US and Canadian market. Due to local regulations, the product will not be made available for this market.

Does the HeatIt thermostat fit in a standard Gira-frame?

Yes. It fits the system 55 that is used by Gira and other premium manufacterers.

Is there any information or manuals available in German?

Yes. You will find relevant information in German following this link »

The product must be installed in accordance with the current version of the installation guide and national building codes. See the installation guide for further information.
