Data Sheet
Danfoss Link™ Hydronic Controller
Application
Danfoss Link™ HC is a part of the Danfoss Link™, a
programmable, wireless control system for heating systems in residential buildings.
The Danfoss Link™ HC allows control of hydronic
oor heating systems. The system oers a wide
range of extended functionalities for optimal
comfort and energy saving, with individual room
temperature control.
The Danfoss Link™ HC includes features like:
2-way wireless transmission, up to 5 or 10 shortcircuit protected outputs for 24 V NC or NO
actuators, relays for both pump and boiler control, selfdiagnosing program, contact for Away
Function, heating/cooling function, regulation
by ON/OFF or Pulse Width Modulation principles
(PWM) etc.
The system can consist of up to three Danfoss
Link™ HC, oering a possibility of up to 30 outputs for even larger systems. The Danfoss Link™
HC has easy connection directly to 230 V power
supply without the need for further transforming,
supplying all actuator outputs with 24 V.
Systems of up to three Danfoss Link™ HC can be
accessed wirelessly by the Danfoss Link™ CC. The
Danfoss Link™ CC oers a wide range of functionalities and features, like individual settings for each
Danfoss Link™ HC output, override and locking
of local room temperature settings, setback and
period programming, system status etc.
Features:
• 2-way wireless transmission at 868.2 MHz, for
higher transmission certainty and direct link
test option on each system component like
room sensors, etc.
• 5 or 10 short-circuit protected outputs with
LED indication.
• Outputs for 24 V NC or NO actuators.
• Valve motion for all outputs approx. 12 minutes
every second week with no heat demand.
• Regulation by PWM (Pulse Width Modulation)
principle.
• Input (ON/OFF) for heating/cooling.
• Input (ON/OFF) for Away Function. When the
switch is closed (ON), the system overrides all
room thermostat set points and change it to
15° C .
• Relay for pump control with automatic pump
motion every third day for 1 min. to avoid damage during standby periods.
• Relay for boiler control, activated only at heat
demand.
• Easy cable xing at each actuator output for
several cable types (squared or circular).
• Automatic self-diagnosis providing indication
of several error possibilities like missing wireless
connection or missing/non-functional actuator
on output, etc.
