The Universal Immersion Heater Timer lets you add a quick warm‑up boost or a longer energy‑saving run with just a single press. Ideal for immersion water heaters, room heaters and any resistive load up to 16 A, this compact electronic timer (85 × 85 × 30 mm) fits neatly into a surface‑mount or in‑wall pattress box.
How it works
Press the button once to select a 15‑minute boost, twice for 30 minutes, three times for 1 hour, or four times for the full 2‑hour “energy saver” mode. A clear visual indicator shows the chosen setting, so you always know how long the heater will stay on.
Key features
- Four preset delay‑to‑off periods – 15 min, 30 min, 1 hr, 2 hr
- Quartz‑regulated timing for reliable accuracy
- 16 A resistive rating – safe for most domestic heaters
- Four screw‑terminal connections with earth for secure wiring
- IP20, Class II protection – meets EN 60730‑1:2011 and EU directives (LVD, EMC, RoHS)
Installation & power
Designed for fixed‑supply wiring (220‑240 V AC, 50 Hz), the timer mounts in a standard socket box and requires only basic wiring skills. It is not intended for direct switching of fluorescent, HID or LED lighting; use a contactor for those applications.
Whether you need a quick 15‑minute heat boost or want to stretch your heating budget with a two‑hour run, this universal timer delivers simple control and peace of mind.
