HBHC25 / HBIR29-20190718-A1
Two channels of self-powered DALI output are available on HBHC25 for connection of two groups of LED drivers. Each group can be set to support different circadian
rhythm profiles on the App.Please note that both channels share the same control settings sent from the occupancy sensor and photocell.

Transceiver Nodes
Communication between the master sensor HBHC25, extender sensor HBIR29 and wall panel HBP01is performed wirelessly.This not only reduces system wiring
complexity and costs, it is also beneficial in that the DALI power supply resources can be dedicated to the DALI DT8 LED drivers, such Hytronik HHC2045 and HHC2050L.
Commissioning and programming of the system is via the Hytronik APP using a enabled smart device using Android or iOS operating systems.Please refer to
our App user guide for more details.
Three push terminals (P1, P2,P3) are available on the HBHC25 master sensor for end-users to switch on/off or change the light brightness and colour
temperature of the two DALI channels temporarily. The settings will revert to the automatic timing profile (circadian rhythm mode) after sensor time-out.
* Long push on P1: adjust the hold-time light brightness of DALI channel 1;
Short push (<1s) on P1: on/off function
* Long push on P2: adjust the hold-time light brightness of DALI channel 2;
Short push (<1s) on P2: on/off function
* Long push on P3: cycles through colour tuning on both channels.
Short push (<1s) on P3: resume automatic circadiam rhythm mode.

*Note:
The push inputs are fixed by hardware
and are not configurable in the app.
Controlled light output brightness colour appearance can enhance a user’s day-to-day mood, wellbeing, productivity and attention levels. The user can select and
customize the biodynamic lighting curve with pre-programmed colour (CCT) and brightness (LUX) control which automatically changes according to the time of the day.

Time sustainability: Each Hytronik circadian rhythm sensor or touch panel can keep the time runing for up to 2 weeks (sensor) or 1month (panel) during power failure.
The built-in photocell performs the function of reading the natural daylight, and maintaining the lux level by calculating how much artificial light is needed according to
the target lux level required by the profile preset.

HHC2045 and HHC2050L are specially designed to work with the Hytronik Human Centric sensors. Dual channel tunable white LED driver for accurate white balance
and intensity control.
