Astronomical time switch SELEKTA 171 top2 RC

The SELEKTA 170 top2 RC astronomical time switch from Theben with weekly program and three special programs per channel is easy to program using OBELISK top2 software. The Astro function can be deactivated so that the SELEKTA can be used purely as a time switch.

Description

Order No. 1710100
Astronomical time switch with weekly program
Time synchronisation via connection of external DCF or GPS antennas, additional posititioning for astronomical program with GPS (GPS not with 24 V device)

3 special programs with yearly date function per channel
Fixed public holidays or date ranges and public holidays dependent on Easter
Astronomical times with other night interruption / fixed ON switching
permanent ON or OFF switching
Count-down timer
Astronomical time switch function (automatic calculation of sunrise and sunset times for the whole year)
Offset for adjusting of sunrise and sunset times
Position data via coordinates or country/city lists can be programmed
Fixed ON-OFF switching times can be programmed (e.g. night time interruption)
Simulation of switching times (calculated astronomical times and programmed ON/OFF switching times)
Reversible astronomical mode (evenings ON – mornings OFF or evenings OFF – mornings ON) or can be deactivated
