Flow setting floor heating at the distribution box l/min

they break... we also have a Roth distributor.

The key is for the valve below the actuators (the dark gray things where the red cap sticks out at the flow.)

Thanks for the hint. Do they break immediately if you turn them even just once? Unfortunately, I already turned such a red cap once as a test attempt :eek: Can I see somewhere (e.g., that the flow rate then goes to 0 l/min) if something got broken because of it?

They don't break immediately, but they do break off easily. You can't adjust anything on the tubes at the distributor, so keep your hands off them. If they are broken, water will leak out, so they become leaky.

Phew, then I was lucky again. Nothing broken and no water leakage either.

Hello everyone,

I have some follow-up questions regarding the handling of the Roth system and have created a new image including the designation of the positions.

According to the Roth sticker above, the display at the flow serves only to shut off the heating circuit. Where exactly do you shut off the heating circuit? At position 1, 2 or 3? Can you tell from the display that a heating circuit has been shut off (e.g., does the float in the glass then rise to 0 at the top or completely down)? I accidentally turned something at position 1 because I thought that was where you adjust the flow rate. Now I’m not sure if I have thereby shut off the heating circuit (if it is position 1).

Where exactly do you adjust the flow rate in the lower area at the return? At position 4, 5, or 6? Can you also see a change immediately at the display above, and is clockwise = decrease flow and counterclockwise = increase flow?

If you have adjusted position 1, it would be sensible to turn position 1 back, wouldn’t it? ;-)

You can read the flow rate on the sight glass below position 1, 0 at the top and 5 at the bottom.

You can limit the flow rate at position 4 with a normal heating square key.
Limiting means turning clockwise. It may be that you have to make a few turns first before any change occurs.
Afterward, small turns will affect the flow rate, which you can read at the top again.

Is the following logic also true for position 1?
Clockwise = close heating circuit
Counterclockwise = open heating circuit

So I would have to turn it somewhat counterclockwise. Is there a stop, or will I eventually unscrew the glass part?

By the way, it is about the two bedroom circuits. Or can you see from the picture that the two heating circuits are normally open?
