Danfoss Icon™ 24V Master Controller
Description
Ordering
Danfoss Icon™ is a modular heating system for
individual room control.
It can be configured as a wired or wireless system
or as a combination, if required.
The center of the system is the Danfoss Icon™
Master Controller 24 V, which configures and ties
the system together.
Installation and set-up of the Danfoss Icon™
Master Controller 24 V is made easy by using the
pre-defined application and intuitive touch user
interface.
The system offer following features (some
require Expansion Module):
• Automatic balancing (PWM+), which ensure
that the hydraulic balancing of the system is
done by the master controller based on the
actual room demand.
• Requires no pre-setting on the manifold.
• On/Off control possibility.
• NC/NO actuator functionality.
• Cooling change over (require an Expansion
Module).

Danfoss Icon™ Master, 24 V, 10 ch. 088U1071
Danfoss Icon™ Master, 24 V, 15 ch. 088U1072
• Supports 2, 3 or 4 pipe applications in various
configurations (please see Expansion Module
application guide for all configurations).
• Supply temperature control (require an
Expansion Module), can be set to either a
fixed temperature or demand based supply
temperature control.
• 230 V power output with protected earth for
circulation pump.
• 230 V power output (for e.g. always on).
• Heat demand signal output (for e.g. potential
free relay).
• Can be made wireless by adding a Radio Module
(required for wireless installations).
• Powerline communication (for 24 V wired
thermostats).
• Possibility to combine wired and wireless
thermostats in same installation.
• APP functionality, for iOS and Android devices
(require APP Module).
