The 20 Way + 4 + Heater MDF Lighting Timer Board is a high-capacity centralised power and lighting control system featuring 20 timed lighting sockets, 4 constant auxiliary sockets and a dedicated heater connection.
Designed for larger professional lighting installations, the board brings multiple lighting outputs and supporting environmental equipment together on a single organised, wall-mounted MDF control board.
The 20 timed sockets allow multiple compatible lighting systems to follow the same automatic schedule, while 4 constant auxiliary sockets provide continuous power for compatible equipment such as extraction and circulation fans.
A separate heater connection provides additional flexibility for environmental management, making this configuration particularly useful where lighting, ventilation and heating equipment need to be managed from one central location.
Why choose the 20 Way MDF Lighting Timer Board?
- 20 timed lighting sockets - centralised automatic control for a large multi-light installation.
- 4 constant auxiliary sockets - suitable for compatible fans and other equipment that needs continuous power.
- Dedicated heater connection - provides an additional connection specifically for compatible heating equipment.
- Integrated lighting timer - automatically manages the timed lighting circuit.
- Contactor-controlled switching - designed to switch the substantial electrical loads associated with multiple lighting systems.
- 100A board specification - high-capacity configuration designed for larger installations.
- Centralised power distribution - keeps lighting and associated environmental equipment organised in one location.
- MDF mounting board - components and sockets are arranged on a rigid board for fixed installation.
- Professional installation format - suited to larger horticultural lighting installations where individual plug-in timers are impractical.
20 timed sockets for large lighting installations
The main section of the board provides 20 timed UK sockets. These allow compatible lighting equipment to be connected to a central switching system rather than relying on numerous separate plug-in timers.
The integrated contactor system handles the switching function, allowing the timer to control the lighting schedule without the lighting load passing directly through the timer contacts.
This type of arrangement is particularly valuable with larger lighting installations, where simultaneous switching can place substantial demands on ordinary domestic timing equipment.
The actual lighting equipment connected to the board must be suitable for the electrical supply and installation. Total circuit loading should be calculated as part of the electrical design rather than assuming that every socket can automatically be operated at a particular wattage.
4 constant auxiliary sockets for fans & equipment
In addition to the 20 timed lighting outlets, the board provides 4 constant auxiliary sockets.
These outlets are useful for compatible equipment that needs to remain powered independently of the lighting schedule. Typical applications include extraction fans, intake fans, circulation equipment and environmental control devices.
Separating constant-power equipment from the timed lighting circuit means ventilation can continue operating when the lighting switches off, where that is required by the environmental control strategy.
Dedicated heater connection
This version of the MDF timer board also includes a dedicated heater connection, distinguishing it from standard lighting and auxiliary-only configurations.
Heating can be particularly useful during lights-off periods, when the heat generated by horticultural lighting is no longer contributing to the growing environment.
The heater outlet provides a convenient connection point for compatible heating equipment as part of the overall installation. The electrical requirements and control method of the specific heater should always be checked before connection.
Why use a contactor timer board?
Switching a large number of lighting systems is very different from controlling a single low-load appliance. Lighting equipment can produce significant starting loads, particularly with HID and other ballast-based systems.
A contactor allows the timer to control the switching operation while the contactor itself handles the larger electrical load. This is a much more appropriate architecture for multi-light installations than attempting to place the complete lighting load through an ordinary plug-in timer.
Bringing the timer, contactor system and socket outlets together on one board also creates a cleaner and more manageable installation, making connections easier to identify and access.
Professional fixed installation
A 20-way timer board is a substantial piece of electrical distribution and control equipment and should be treated accordingly.
The board should be securely mounted in a suitable dry location with sufficient access for operation, inspection and maintenance. It should be protected from irrigation water, spray, condensation and other sources of moisture.
The electrical supply, protective devices, cable sizing, circuit arrangement and total connected load must all be appropriate for the installation.
Installation and electrical supply arrangements should be assessed and completed by a suitably qualified electrician.

20 Way MDF Lighting Timer Board FAQs
What is the difference between the timed and auxiliary sockets?
The 20 lighting sockets operate according to the timer schedule. The 4 auxiliary sockets provide constant power, making them useful for compatible equipment that needs to continue operating independently of the lighting cycle.
Why does a large lighting installation need a contactor?
A contactor provides heavy-duty electrical switching for the connected lighting circuits. The timer controls the contactor rather than carrying the complete lighting load through its own switching contacts.
Can the auxiliary sockets be used for extraction fans?
Yes. Compatible extraction, intake and circulation fans are typical applications for constant-power auxiliary sockets because they can remain powered when the timed lighting circuit switches off.
Does the heater socket switch off with the lights?
The heater connection is separate from the main bank of timed lighting sockets. The operating arrangement should be checked against the board configuration and the requirements of the heating equipment during installation.
Can I use all 20 lighting sockets at the same time?
The number and type of lights that can operate simultaneously depends on their electrical characteristics, the board specification and the electrical supply. Total connected load should be assessed as part of the installation rather than determined by socket count alone.
Can this timer board be used with LED lighting?
It can be used with compatible lighting equipment where the electrical characteristics of the fixtures, drivers and switching system are suitable. The connected load and any starting or inrush current should be considered when specifying the installation.
Where should an MDF lighting timer board be mounted?
It should be securely mounted in a suitable dry location, protected from irrigation water, spray and excessive moisture while remaining accessible for operation, inspection and maintenance.
Does a 100A board mean I can automatically draw 100A from the mains?
No. The 100A figure is the board specification and does not determine what the premises electrical supply can provide. Available supply capacity, circuit protection, cabling and connected load must all be assessed for the individual installation.
Does this need to be installed by an electrician?
A high-capacity multi-way lighting control board requires an appropriately designed electrical supply and protection. Installation and supply requirements should be assessed and completed by a suitably qualified electrician.
Why use one central timer board instead of multiple extension leads?
A purpose-designed timer board centralises lighting control, contactor switching and auxiliary connections in one organised installation. It is designed for multi-light control rather than building a large system from numerous independent domestic extension leads and timers.
