Colour Touch Screen Heating Thermostat HIQ 425

This Thermostat is a colour touch screen unit and is designed for electric or hydronic underfloor heating
systems, as well as radiant heating.

Using a 4.3inch colour touch LCD display, the working status can be easily viewed. With built-in four
languages, you can select the language you want to display.

The thermostat has five modes, and in each mode the system can work according to your desired pre-set
temperature.

Simple heat regulation sends On/Off commands to the heating system according to pre-selected
temperatures. The thermostat control algorithm includes an anticipation function which reduces the
discrepancy between the thermostat reading and the temperature at the centre of the room.

Choose from three sensor settings: Ambient (built-in sensor)- to control the air temperature; Floor - to
control the temperature using the floor probe; Ambient and Floor - to control the ambient air, and show
floor temperature by using the floor probe.
