Zoning boiler control with
BDR90 Relay module or RF
bridge
In its simplest single-zone
configuration evotouch senses and
controls the temperature in the main
room, using its internal sensor and
Boiler
calling for heat from the boiler via the
Boiler Relay or Opentherm Bridge
according to the desired set point.
HR80 radiator control with
central operation
The evotouch can control up to 8 zones
using the HR80 radiator controller. The
evotouch uses the valve position of the
HR80 to determine whether or not heat
HR80
is required. It will control the boiler via
the boiler relay or Opentherm Bridge.
In this configuration only the set point
Boiler
is sent to the HR80s. The HR80s will
compare the received set point to
the measured zone temperature and
adjust the valve position accordingly.
Under floor heating control
with central operation and
room units DT92/HCW82
The evotouch can also integrate with
DT92 an under floor heating controller, and
room units DT92/HCW82, to provide
individual control of up to 8 rooms.
HCW82
The DT92/HCW82 room sensors and
set point adjusters communicate
directly with evotouch.
