Drayton 25473 LP112 (Mk4) 2 Channel Programmer

The Drayton 25473 LP112 Mk4 is a sophisticated yet user‑friendly electronic programmer designed to give homeowners full control over their central heating and hot water systems. With its dual‑channel architecture, the device allows separate scheduling for heating and hot water, ensuring optimal comfort while reducing energy consumption.

Key Features

• Dual Channel Operation: One channel manages the heating circuit, while the other controls the hot water supply. This separation lets you tailor each schedule to your daily routine.
• 24‑Hour Programming: The unit offers a full 24‑hour timetable with up to eight distinct time slots per day. Each slot can be set for a specific temperature, allowing precise control over when heating or hot water is activated.
• Temperature Range: The programmer accepts input temperatures from 5 °C to 35 °C, covering the typical range required for domestic heating and hot water systems.
• LED Display & Touch Interface: A clear, back‑lit display shows current settings and time. The touch interface makes it simple to navigate menus and adjust schedules without needing a separate remote or key.
• Power Supply: Operates on standard mains voltage (230 V AC) with an internal power supply that ensures reliable performance even during minor voltage fluctuations.
• Compact Design: The compact, lightweight chassis fits easily into most boiler rooms or control panels without requiring extensive modifications.

Installation & Compatibility

The Drayton LP112 Mk4 is engineered for straightforward integration with existing central heating and hot water systems. It connects directly to the control board of a standard boiler, replacing or supplementing older mechanical timers.

1. Power Off: Switch off the mains supply to the boiler before beginning installation.
2. Wiring: Connect the programmer’s input terminals to the boiler’s control board, following the wiring diagram supplied in the manual. The device typically requires a 24 V DC power source from the boiler for its internal electronics.
3. Mounting: Secure the unit on a flat surface using the provided mounting brackets or adhesive pads. Ensure it is positioned away from direct heat sources to avoid overheating.
4. Power On & Test: Restore mains power, then use the touch interface to verify that the programmer detects the boiler’s status and that the heating/hot water circuits respond correctly to programmed schedules.

Programming Workflow

The LP112 Mk4 offers a logical, step‑by‑step workflow for setting up your heating and hot water schedules:

1. Select Channel: Choose either the heating or hot water channel from the main menu.
2. Add Time Slot: Tap “Add” to create a new time slot. Specify start and end times, then set the desired temperature for that period.
3. Repeat: Continue adding slots until you have covered all required periods of the day. The device allows up to eight slots per channel.
4. Save & Exit: Confirm each entry and exit back to the main menu. The programmer will automatically store your settings in non‑volatile memory, ensuring they persist through power cycles.

Energy Efficiency Benefits

By allowing precise control over when heating and hot water are activated, the LP112 Mk4 helps reduce unnecessary energy use. Typical savings include:

• Lowered boiler running time during off‑peak hours.
• Reduced standby heat loss by turning heating off during periods of inactivity (e.g., nighttime).
• Optimized hot water delivery, preventing the “hot water loop” from staying on longer than necessary.

Maintenance & Troubleshooting

The device is designed for minimal maintenance. However, users should periodically check:

• LED display clarity and back‑light functionality.
• Secure wiring connections to avoid loose contacts.
• Firmware updates (if available) through the manufacturer’s support portal.

If the programmer fails to respond, verify that:

1. The mains supply is active and within rated voltage.
2. The boiler’s control board is providing the required DC power.
3. No error codes appear on the display; consult the troubleshooting section of the user manual for specific code meanings.

Why Choose the Drayton LP112 Mk4?
