2.1 Precaucions de seguretat

Before commencing any installation work, ensure the mains electricity supply to the heating system is completely isolated at the consumer unit or fuse box. Installation should only be carried out by a competent person and in accordance with the latest IEE Wiring Regulations.

• Assegureu-vos que totes les connexions de cablejat siguin segures i correctes.

2.2 Muntatge

The LP522 (Mk4) is designed for direct replacement of many existing programmers, often utilizing the same industry-standard backplate. If replacing an older unit, carefully remove the old programmer by loosening the retaining screws at the bottom and lifting it off the backplate. The new LP522 (Mk4) can then be positioned onto the existing backplate and secured by tightening the screws.

If a new backplate installation is required, mount the supplied backplate securely to a flat wall surface, ensuring it is level. Refer to the wiring diagram provided with the physical product for terminal connections.

Wiring should be performed by a qualified electrician. The LP522 (Mk4) operates on 230 Volts AC. Ensure correct connections for Live, Neutral, Heating On, and Hot Water On terminals as per the product's wiring diagram. Incorrect wiring can cause damage to the unit or the heating system.

Once installation is complete and verified, restore the mains electricity supply. The programmer's LCD screen will illuminate, and the internal clock will automatically set the correct time and date, including adjustments for summer/winter time changes. No manual time setting is typically required upon initial power-on.
