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.
