The Danfoss HC (Hydronic Controller) is part of the wireless Z-wave controlsystems for heating systems in residential homes.

The Danfoss HC allows the control of warmwater floor heating systems. The system offers a big bandwidth of advanced functions for optimal comfort and energy savings and allows a single room temperature control.

The Danfoss HC includes among other things: 5 short circuit safe outputs for 24V actuator drives NC or NO, Relays for pump and boiler control, self-testing program, regulation by ON/OFF- or PWM-principle (pulse width modulation) etc.

The system can exist of multiple Danfoss HC for bigger systems with more than 5 actuators drives. The Danfoss HC has a direct connector to a power supply of 230V. Because of that you do not need an additional transformer but all actuator drives will be supplied with 24V power.

FEATURES :

• Controlling of warmwater floor heating systems
• 5 short circuit protected outputs with LED notice
• Output for 24V actuator drive NC or NO
• Guarantee of valve function at all outputs even when there is temperatur control, every 14 day valve movement for ca. 12 minutes
• Regulation by PWM-principle (pulse width modulation)
• Relays for pump regulation with automatic 1 minute pump start-up on every third day, to avoid damages during the Standby time periods
• Relays for boiler regulation, only active during warming needs
• Automatic self diagnostics to show lost connection to the device
