Common questions
What does the Telis 1 Chronis RTS do?
Part 1805237 is a single-channel Somfy RTS handheld remote with a built-in timer. It controls one motor or group by hand and can also raise and lower it on a daily schedule, so shades, blinds and awnings move while you are away.
How does the timer work?
The timer runs one open and one close event per day, with separate schedules for weekdays and weekends. Somfy sets factory defaults of 7:30am up and 8:00pm down, and you can program your own times.
Which motors does it work with?
Somfy lists it for all motorized shades, blinds, drapes, rolling shutters and awnings with RTS. Examples include the Sonesse 506S2 RTS (1001809), the Maestria RTS 510A2 (1134082) and the Irismo 35 Mini DC RTS drapery motor (1003004).
What range does it have?
It transmits on 433.420 MHz, and Somfy rates its range at 656.2 ft in open field. RTS radio needs no line of sight, so you do not have to aim the remote at the shade. Walls and building materials shorten the range indoors.
What batteries does it use, and how big is it?
It runs on 2 LR3 (AAA) batteries. The remote measures 5.94 in by 1.85 in by 0.71 in, and a wall mount clip is available. Somfy rates it IP 30, from 32 °F to 140 °F, with a 5-year warranty.
What if I need more channels or app control?
For several shades on separate channels, choose the Situo 5 Channel RTS Pure remote (1870575) or the Telis 16 Channel RTS Pure (1811081). For app control, schedules and voice commands, add a Somfy TaHoma Switch (1871037).
