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 floor heating systems. The system offers 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, offering 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 offers 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 fixing 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.
