Check It Works With Your Towel Rail
Works with Single Heat and ER-Touch thermostatic elements.
An external timer needs a towel rail that restarts heating when the power returns. To check, turn your towel rail on, switch its fused spur off, wait 10 to 15 seconds, then switch it back on. If the rail carries on heating from where it left off, it will work with this timer. The ER-Touch thermostatic element and the Single Heat element are designed for it.
Where to Fit It
Mount the timer on the wall, outside the bathroom, in a 25mm deep back box. It replaces a standard fused connection unit: the supply connects to L IN and N IN and the towel rail to L OUT and N OUT. If the back box is metal it must be earthed. Installation must be carried out by a qualified electrician. Prefer to control the rail from your phone? See our WiFi fused spur timer.
Frequently Asked Questions
Q.
Which heating elements does the digital timer work with?
A. It is designed for the Single Heat element and the ER-Touch thermostatic element. For any other element, use the simple power-off test described on this page before you buy.
Q.
How do I check my towel rail will work with an external timer?
A. Turn the towel rail on. Switch its fused spur off, wait 10 to 15 seconds, then switch it back on. If the rail carries on heating from where it left off, it will work with an external timer.
Q.
Do I need a Booster controller as well?
A. No. This timer has its own 1 or 2 hour BOOST button, and the ER-Touch thermostatic element has a BOOST timer built in (1 to 5 hours). A separate Booster controller is not needed.
Q.
How many on and off times can I set?
A. Up to four ON/OFF periods per day. Choose 7 Day, 5 Day (weekdays only), Weekend (Saturday and Sunday only) or Individual day mode, depending on how you use the towel rail.
Q.
How does the BOOST button work?
A. Press BOOST once to switch the towel rail on for 1 hour, twice for 2 hours, and a third time to switch it off again.
Q.
What does the ADV button do?
A. Press ADV once to keep the load on until the next timer OFF setting. Press it twice to override the timer, and the load stays on until you press ADV again to return to timer mode.
Q.
What happens in a power cut?
A. A built-in battery keeps the time and your programme for up to 4 weeks without mains power.
Q.
Can I program the timer to run past midnight?
A. Yes. Program the ON time as normal, then set the OFF time to 00:00.
Q.
Can I install the timer in a bathroom?
A. We recommend mounting the timer outside the bathroom, for example in a hallway or landing, and having it fitted by a qualified electrician who can confirm the right location for your layout.
Q.
Do I need an electrician to fit it?
A. Yes. It must be installed by a qualified electrician following local regulations. It fits a 25mm back box and takes 2 x 2.5mm or 1 x 4mm cables per terminal.
Q.
What is the difference between the digital timer and the WiFi timer?
A. The digital timer is programmed on the unit itself and needs no app or WiFi. The WiFi timer is controlled from the Tuya Smart app on your phone and works with Alexa and Google Assistant.
