Application Manual 21
Application description
This application shows two heating circuits: one for radiator MK1 and one for underfloor heating MK2. The HR80 radiator
controllers belong to the heating circuit MK1 (zones 2 – 6) which use their own integrated room sensor.
Zone 1 (underfloor heating MK2) is controlled by the mixing valve controller HM80 and the evotouch controller’s internal
room sensor is used to measure the room temperature. The evotouch controller also sends the room temperature
setpoints and parameters to the HM80.
For optimal operation, the parameters can be set at the mixing valve for each individual zone’s HM80.
The evotouch controller can control up to 8 zones with HM80. However, each zone requires its own HM80 and sensor
device, e.g. HCF82, HCW82 or DT92.
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.
Steps to do
Activate internal room sensor of the 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 2 – 6. See section 4.3.1
Bind the f
evotouch controller to each HR80’s actuator individually for each zone 2 – 6. See section 4.3.2
Bind the f evotouch controller to the mixing valve controller HM80 for zone 1. See section 4.6
Optional: Bind the f
evotouch controller to the BDR91 / HC60NG relay module
for boiler feedback.
See section 4.7
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
