Presentation

WXE weather-compensated controllers are advanced controllers for regulating space heating or cooling and domestic hot water heating in residential and more demanding heating systems. They are designed for use in systems with radiators, underfloor, wall, ceiling or convector heating and cooling. Depending on the selected model, they enable control of up to two heating circuits, the use of various heat sources, a thermal storage tank, a solar system and remote control via the SeltronHome system.

Radiator room heating system control.
Floor heating or cooling system control.
Convector heating or cooling system control.
Wall or ceiling heating or cooling system control.
Domestic hot water heating.
Control of systems with one or two heat sources.
Control of systems with a thermal storage tank.
Domestic hot water heating with a solar system on selected models.

Installation of the WXE controller

The WXE controller is used for the control of modern heating systems or as a replacement controller in older heating systems.

It can be installed into a standard cutout on the boiler or on the wall.

Remote control with the help of SeltronHome system

WXE controllers can be connected to the SeltronHome platform, which enables remote monitoring and control of heating via a smartphone or tablet.

Remote monitoring is possible via the CLAUSIUS app, designed for end users, and the KELVIN app, designed for service technicians.

The CLAUSIUS app allows users to set the desired room temperature, select the heating operating mode, and view and modify time programs on a smartphone or computer.
