Main highlights

This bypass set branches off some pool water and directs it to the solar absorber. It is then fed back to the normal water circulation optimised by 45° angle.
The bypass is required to integrate solar absorbers into the filter circuit.
The absorber should not be integrated directly, otherwise the heat cannot be properly released into the water. Finally, you need to give the water some time to heat up. Therefore, the flow must be reduced by bypass.
Items are delivered individually and unglued
Bypass for solar absorber Ø 50 mm including glue, cleaner and PVC pipe.

Without N conductor: works with or without N conductor – without N conductor, please use the iluminize bypass according to the circuit diagram with less than 20 W LED or for afterglow of the lamps
Optional switching via button: Switching can also be done additionally/exclusively with one or more rocker buttons (close type, from several locations as with a changeover switch, not included). Due to the special operation without zero conductor, the button (normally closed) must be connected directly. Push buttons with status lights must not be used.
Fits in the switch box: thanks to the dimensions of 45 mm x 45 x 23 mm, the Mini Zigbee 3.0 switch actuator fits behind the switch into a deep (60 mm, no other cables and clamps) switch box, but can also be mounted in the lamp or on the ceiling.
Compatible: works with the well-known Zigbee systems and voice controls. Important: the device is delivered without remote control/coordinator and requires additional components for operation. The Philips Hue Bridge also supports HomeKit, but not entertainment. See product description for further compatibility.
