Module 1 of 5

What limits are, and which motors set them from the remote

What limits are and why getting them right protects the shade. You will also learn how to tell whether a motor sets limits from the remote.

3 lessons, then a scenario check.

What limits are, and which motors set them from the remote

Limits are the two stops

Limits are the two points where the motor stops on its own: fully up and fully down.

ExampleFully up should stop with the hem bar just clear of the headrail. Fully down should cover the window with the hem bar where it looks right.

TWO STOPSUpper limitLower limit

What limits are, and which motors set them from the remote

Too far or too short

Set them too far and the shade wraps over the roller or pulls the hem bar into the headrail. Set them too short and the window never fully covers.

ExampleA shade that wraps over the roller on the way up has an upper limit set too high.

What limits are, and which motors set them from the remote

Electronic or mechanical limits

Most Somfy RTS motors store electronic limits, set from the remote. A few heavy-duty motors use mechanical limits, set on the motor head. Check the spec sheet under limit type. This course covers electronic limits.

On the jobLook up the part number before the visit. The spec sheet tells you whether you need a remote or a tool for limits.

Check yourself

Where do you confirm whether a motor has electronic or mechanical limits?

Module 2 of 5

Power one motor at a time

One rule that prevents the most common limit-setting mess: only the motor you are working on gets power.

2 lessons, then a scenario check.

Power one motor at a time

Power only the motor you are setting

Somfy's guide opens limit setting with this rule. RTS motors in setting mode respond to the remote, and a second powered motor nearby can pick up the same commands.

ExampleThree shades on one circuit, all powered. The second shade can pick up the same commands while you set the first. Now you have two shades to redo.

ONE AT A TIMEPoweredUnpluggedUnpluggedProgram one motor. Leave the rest off.Other powered motors can pick up the same commands.

Power one motor at a time

On a job with several shades

Unplug the others, or leave their pigtails disconnected, until each one is done. Set battery motors one by one before you mount the next.

On the jobLeave the pigtails of the other motors unplugged until the first one is done, then move down the line.

Check yourself

Why power only one motor while setting limits?

Module 3 of 5

Enter setting mode and check direction

Getting the motor ready: enter setting mode, then make sure DOWN really means down before you store anything.

3 lessons, then a scenario check.

Enter setting mode and check direction

Hold UP and DOWN together

Press and hold UP and DOWN together until the motor jogs. A fresh or reset motor is now in setting mode with the remote you are holding.

ExampleA fresh motor out of the box. Hold UP and DOWN together, the shade jogs, and you are in setting mode.

ENTER SETTING MODEUPMYDOWNUP + DOWNhold until the shade jogsFresh or reset motor

Enter setting mode and check direction

Check the direction

Press and hold DOWN. The shade must travel down. If it goes up, the motor is reversed, which depends on which end of the roller it sits.

Watch forDirection depends on which end of the roller the motor sits. A shade can be installed correctly and still run backward at first.

CHECK DIRECTIONHold DOWN.The shade must go down.Goes up? The motor isreversed. Fix it with MY.

Enter setting mode and check direction

Reverse it with MY

Press and hold MY until the motor jogs, and the direction flips. On WireFree Li-ion motors Somfy notes this hold is about 2 seconds.

On the jobFix direction before you store any limit. A limit set with reversed buttons is a limit you will set again.

Check yourself

You press DOWN and the shade rises. What do you do?

Module 4 of 5

Set the upper and lower limits

Store the top stop, store the bottom stop, confirm both. Three button combinations and you are done.

4 lessons, then a scenario check.

Set the upper and lower limits

Store the upper limit

Run the shade to where you want the top stop. Press and hold MY and DOWN together until the shade starts moving, then let go. The upper limit is stored and the shade heads down.

On the jobSet the top first. The shade starts down on its own once the upper limit is stored, which is your sign it worked.

UPPER LIMITUPMYDOWNMY + DOWNhold until it movesShade at your top stop

Set the upper and lower limits

Store the lower limit

Stop the shade at the bottom you want and fine-tune with UP and DOWN. Press and hold MY and UP together until it moves, then let go. It returns to the upper limit by itself.

On the jobTake your time at the bottom. Nudge with UP and DOWN until the hem bar sits exactly where the customer wants it.

LOWER LIMITUPMYDOWNMY + UPhold until it movesShade at your bottom stop

Set the upper and lower limits

Confirm both limits

Press and hold MY until the motor jogs. That confirms both limits.

Watch forIf the shade does not jog when you hold MY at the end, the limits are not confirmed. Hold MY again.

Module 5 of 5

Save a favorite position with MY

The favorite position most customers end up using every day: set it, use it, change it.

4 lessons, then a scenario check.

Save a favorite position with MY

MY stores one favorite stop

The MY button saves one position between the limits, handy for glare control or a half-open privacy height.

ExampleA west-facing office lowers shades halfway every afternoon. A saved MY position does it with one press.

Situo 5 RTS Pure (1870575): the center button is MY

Save a favorite position with MY

Set your MY position

Move the shade to the height you want. Briefly press MY to stop it, then press and hold MY until the shade jogs.

On the jobAsk the customer where they want it before you leave. Setting MY takes seconds while you are there.

YOUR MY POSITIONMYOne favorite stopbetween the limits.Glare control or ahalf-open privacy height.

Save a favorite position with MY

Use it

Press MY while the shade is stopped. If it is moving, press MY twice: the first press stops it and the second sends it to your spot.

Watch forIf the shade is moving, one press of MY only stops it. The second press sends it to the saved spot.

GO TO MYUPMYDOWNPress MYtwice if it is movingOnce if it is stopped

Save a favorite position with MY

Delete it

Press MY briefly to go to the saved spot. Then press and hold MY for about 5 seconds, until the shade jogs.

ExampleThe customer wants a new MY height. Delete the old one, then set the new one the same way you set the first.

Check yourself

The shade is moving and you want it to go to the My position. What do you press?
