Application description
This is a typical application which shows the combination of underfloor heating and radiator control. Zones 1 and 2 are
controlled by the underfloor heating controller HCE80 and zones 3 – 6 by radiator controllers HR80.
Zone 1 uses the internal room sensor from the evotouch controller, while zones 2 and 3 use the DT92 room unit to
measure the room temperature and remote setpoint adjustment.
Zones 4, 5 and 6 individually use their HR80's integrated room sensor.
All peripheral devices communicate directly with the evotouch controller. The room temperature setpoints can be altered
manually or by e.g. time program or lifestyle actions with the evotouch controller.
This mixed application can be used for up to 8 zones.
Options
• Heat demand
The evotouch controller calculates the heat demand and communicates it to the BDR91 / HC60NG boiler relay 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.
