Introduction

The APT analogue time switch controls the on and off timing of electrical equipment such as immersion heaters, lighting, and other devices that require on/off settings.

The IMM24 range is best known in the market for working with immersion heaters and stands out for its reliability and ease of use.

APT IMM24 Versions

APT offers three IMM24 versions:

• IMM24 - This classic surface mount version
• IMM24F - If you prefer a flush mount version
• IMM24EC - Another surface mount option, but with an automatic rotary on/clock/off control for permanent on/off or timed operation.

Benefits of Time Switches for Immersion Heating

Time switches allow you to control when your immersion heater is on, ensuring it's only in use when you need it. This can significantly cut down on energy costs, as you’re not leaving the heater on unnecessarily. Additionally, it helps prevent potential fire hazards by ensuring the heater isn't left on when it shouldn’t be.

Compact Design and User-Friendly Features

The BEAB-approved APT IMM24 and IMM24EC come with compact dimensions and a tappet 'time' selector for fast and easy fingertip control. The time switch is user-friendly and straightforward to operate. The 30-minute increment tappets and 24-hour dial offer the convenience of repeating a cycle daily, making it easy to program the switch to operate according to your schedule.

The time switch also comes with a surface mounting box containing 2x cable clamps, making installation quick and easy. The impact-resistant housing ensures that the switch will last for years, even in tough conditions. Additionally, the slider switch allows the unit to be set for continuous on or off modes, in addition to the programmed settings, providing further flexibility and convenience.

What is BEAB?

The British Electrotechnical Approvals Board (BEAB) certification signifies that an electrical product has been independently tested and meets high safety standards. In the UK, BEAB certification provides assurance of safety, regulatory compliance, and quality for consumers.

The terminals can accommodate 2x 1.5mm conductors, making it easy to connect to your immersion heater.
