Application description
The underfloor heating controller controls 6 zones individually. For zone 1, the evotouch internal room sensor is used.
All other zones (2 – 6) require their own room unit DT92 in order to measure the room temperature and adjust the room
temperature setpoint remotely.
The DT92 communicates directly with the evotouch controller in order to exchange the room temperature setpoints that
can be altered by manual override, time program or lifestyle actions at the evotouch controller.
The underfloor heating controller communicates only with the evotouch controller directly and receives the room
temperature and room temperature setpoint for each zone individually.
In total, 8 zones can be controlled individually.
Options
• Heat demand
The evotouch controller calculates the heat demand and communicates it to the boiler relay BDR91 / HC60NG or
OPENTHERM-Bridge which control the boiler.
• Outdoor sensor
The HB85 outdoor sensor measures the outside temperature. It must be installed if data is required.
Steps to do
