The unit supports multiple daily switching events, enabling scheduled control of lighting, heating, pumps and other appliances without manual intervention.

Advantages

The timer offers a clear and consistent schedule capability with 16 program slots, allowing precise time-based control across different days and periods. Its compact design fits standard switch boxes and replaces conventional switches while adding programmable functionality. The hybrid mechanical/electronic timing ensures stable operation and reliable switching accuracy. Installation and programming are intended to be straightforward for electricians and informed DIY users.

Suitable for

• Automating indoor and outdoor lighting circuits
• Scheduling small electric heaters and underfloor heating zones
• Controlling water pumps, circulation pumps and ventilation fans
• Managing timers for signage, display lighting or seasonal decorations

Key specifications

• Programmable capacity: up to 16 independent on/off programs
• Timing type: combined mechanical and electronic timing mechanism
• Mounting form: switch-style, suitable for standard single-gang switch boxes
• Intended load: designed for household and light commercial circuits (observe local wiring limits)
• Daily scheduling: supports multiple switching events per day with repeatable patterns
• User controls: front access for setting programs and manual override

How to use

Install the timer switch in place of a conventional wall switch, following local electrical regulations. Connect line, load and neutral as required for the specific wiring configuration and confirm power is isolated during installation. Use the front panel controls to set the desired on and off times across available program slots, and enable or disable programs according to the daily schedule. Test each programmed event to confirm correct operation and use the manual override to switch the load on or off outside scheduled times.

Usage recommendations

Choose programs appropriate for the connected load and avoid exceeding the circuit’s rated capacity. For timed control of high-power appliances, consult a qualified electrician to verify compatibility and safe installation. Regularly check settings after power outages and perform visual inspections to ensure secure mounting and wiring connections.
