Application Manual 13
Application description
This application shows when the HR80 integrated room sensor should be used or, alternatively, the DT92 remote sensor.
The precise room temperature measurement requires air flow through the HR80 room sensor which is not always possible,
particularly if the radiators are faced with e.g. wood, which causes an imprecise temperature measurement (see examples
in zone 1 and zone 2). Therefore, in zone 1 the internal sensor from the
evotouch controller is used to measure the room
temperature. For zone 2 the DT92 room unit is used which also allows to change the room temperature setpoint remotely
(manual override).
The room temperature from zones 3 – 6 is measured directly by each HR80.
Up to 8 zones can be controlled individually with the radiator controller HR80 in combination with remote units DT92,
HCW82 or HCF82.
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
Activate the internal room sensor of the f evotouch controller for zone 1. See section 4.2
Bind the f
evotouch controller to each HR80’s integrated room sensor individually
for each zone 3 – 6.
See section 4.3.1
Bind the f evotouch controller to each HR80’s actuator individually for each zone 1 – 6. See section 4.3.2
Bind the f
evotouch controller to the DT92 room unit for zone 2. See section 4.8
Optional: Bind the f evotouch controller to the BDR91 relay module / OPENTHERM-Bridge
for boiler feedback. See section 4.5
Optional: Bind the f
evotouch controller to the HB85 sensor for outdoor temperature. See section 4.10
Check RF communication for each sensor and actuator individually. f
