Wiring Diagram
Caution: Please do not connect wires with electricity, so do not expose the wire ends!
The diagram shows connections for an AC220V power plug cable and a wall-mounted boiler signal line. It indicates terminals L (Live), N (Neutral), M (Motor/Pump), NO (Normally Open), COM (Common), NC (Normally Closed), NO1, and NC1. The instructions specify connections for normally closed electric actuators (NO1 to N), normally open electric actuators (NC1 to N), and external circulation pumps (M to N). It also notes that distinction between positive and negative colors is not required for the boiler signal line. Installation must be carried out by professionals due to high voltage.
Wiring Terminal Instructions:
- NO1: Normally closed electric actuator - Connect NO1 and N
- NC1: Normally open electric actuator - Connect NC1 and N
- M: External circulation pump <5A - Connect M and N
Installation Steps
The installation involves several steps, visually represented by diagrams:
- Panel Preparation: Gently pry open the front panel.
- Backplate Installation: Install expansion screw sleeves (e.g., with a spacing of 59mm) on the wall. Place the backplate in the installation position and insert and tighten the screws.
- Connecting Plate: Insert the connecting plate into the square bracket.
- Wire Connection: Connect the wires according to the wiring diagram.
- Mounting the Transmitter: Insert the transmitter panel into the bracket.
- Final Assembly: Cover the panel and complete the installation. The device can then be placed on a desktop or other surface.
Diagrams show:
- Removing the front panel.
- Installing wall anchors and screwing the backplate.
- Connecting the transmitter panel to the bracket.
- Final placement of the device.
