NEW FUNCTION IN 3-Series CLOCK
The ability to read and save the timer configuration wirelessly via an Android phone equipped with an NFC communication module .

Operation
The astronomical timer on the basis of information about the current date, geographical coordinates of the place of its installation automatically determines daily programmed points of switching on and off the lighting. The exact time of switching on and off is determined by calculating the position of the sun relative to the horizon. The program allows you to select one of four control options (the moment the light is switched on and off is set independently):
1. Astronomical sunset and sunrise
2. Dusk / civil dawn
3. Correction - individual correction of the programmed switch-on and switch-off points by the user: angular or time.
4. Time - determination of a "rigid" switch-on or switch-off time independent of the cycle of sunrises and sunsets
Between the programmed switch-on and switch-off points, it is possible to program a night break, i.e. a temporary switch-off of receivers for saving purposes.

Timer functions
AUTOMATIC OPERATION - automatic operation according to programmed switch-on and switch-off points of contacts [switched-on symbol on the left-hand display].
Semi-automatic operation - possibility of manual contact switching on/off during automatic operation. The change will be in force until the next switch on/off resulting from the automatic operation cycle [flashing symbol on the left-hand display].
NOTE: In semi-automatic mode, the contact position is opposite to that resulting from the program cycle (i.e. at night the contact is off, and during the day it is on). Semi-automatic operation works only until the end of the current automatic operation cycle, e.g., entering semi-automatic mode during the day will switch on the light until the program switching time resulting from the astronomical cycle. Then the timer returns to automatic operation (and the light continues to stay on until dawn). The mode is switched on or off using the +/- buttons on the main level.
MANUAL OPERATION -[ON] to permanently switch on the contact (items 1-5) or[OFF] to permanently disconnect the contact (items 1-6) when the AUTOMATIC OPERATION mode is switched off. [no symbol on the left-hand display].
ASTRONOMIC sunrise and sun set - moments when the center of the solar disk touches the horizon (parameter h =-0.583°). For the sake of simplification of calculations, a deviation of a few minutes from the data determined by the "HM Nautical Almanac Office" is allowed.
NOTE: The advantage of setting the on/off moment as a function of the position of the solar disk is that it is insensitive to changes in the duration of dusk/dawn for different seasons, so that the on/off moment always occurs for the same level of brightness.
DUSKNOW and CIVIC D AWN - also calendar - phase of sunset,
in which the center of the solar disk will be no more than 6 angular degrees below the horizon (the solar disk viewed from Earth has a diameter of about half a degree). At this time, the brightest stars and planets appear in the sky (if the air is clear) (the "Evening Star," the "first star" on Christmas Eve). Due to the scattering of light in the atmosphere, there is still generally enough sunlight that it is still sufficient for normal outdoor activities without artificial light sources. Civil dawn (also calendar dawn) - the time before sunrise when the center of the sun's disc is already more than 6 ° below the horizon line.
PROGRAMMABLE ON and OFF POINT - times of contact on (items 1-5) and contact off (items 1-6) determined based on the selected control option: astronomical sunrise/sunset or civil dawn/dusk and location.
NIGHT INTER RUPTION - user-settable temporary shutdown between programmed on and off points.
CONFIGURATION - specify the LOCATION and designate the PROGRAMMABLE ON AND OFF POINTS.
LOCATION - geographic coordinates and time zone of a locality relatively close to the clock installation site. The memory defines locations and time zones of about 1500 localities from 51 countries of the world. It is possible to enter your own settings in the form of geographic location and time zone (UTC).
CODE OF COORDINATES - assigned geographic coordinates for the listed cities to make it easier to enter the location (cities and their assigned codes are given in the table at the back of the manual). The full list of countries and their corresponding codes can be found (at the bottom of the page) in the downloads under the name: Coordinate Code Table.
CORRECTION - acceleration or delay of on/off times in relation to the astronomical time points of sunrise and sunset:
±15° - angular correction for the time of switch-on relative to the position of the center of the sun's disk relative to the horizon
±180 min. - time correction for the moment of switching on as a time offset relative to sunrise/sunset.
DST - Daylight Saving Time - the global name for daylight saving time (free translation: sunlight-saving time). A function to disable automatic time change.
AUTOMATIC TIME CHANGE - Change of time from winter to summer time. Option to work with or without automatic change. The controller is equipped with a time zone selection function so that the switching time is in accordance with the local time.
DATE LIVEPAGE - preview of the set date (OK.).
PROGRAMMABLE ON/OFF POINTS AND LOCATION LIGHTING - possibility to preview the current time of contact switching on and off, as well as the set location (geographical coordinates are displayed) and UTC time zone (in date preview mode successive presses of +/? buttons.
NFC FREE COMMUNICATION - Possibility to read and save the timer configuration wirelessly via an Android phone equipped with an NFC communication module.
PCZ CONFIGURATOR APLICATION - Free application for Android phones and tablets running on Android and equipped with NFC wireless communication module.
Functions:
* preparation of the clock configuration in offline mode (without the need to connect to the clock)
* setting coordinates by selecting a predefined location (coordinate code), directly pointing to the location on the map on the phone or rewriting the current position recorded by GPS on the phone.
* reading and writing configurations to the controller
* quick programming of multiple controllers with a single configuration
* reading and saving configurations to file
* sharing of configurations via e-mail, bluetooth, network drives, ...
