How to Program a Digital Timer
Basic Steps (Most Brands)
- Enter programming mode: Usually press and hold PROG or SET button
- Select day(s): Choose individual days or groups (Mon-Fri, Sat-Sun, etc.)
- Set ON time: Use +/- buttons to set first switch-on time
- Set OFF time: Set when to switch off
- Repeat: Add additional on/off periods if needed
- Save: Press SET or PROG to confirm
- Set temperature: Adjust thermostat to desired heat level
Pro Tip: Set Temperature First
Before programming times, set your thermostat to desired temperature (usually 50-60°C). The timer controls when power is available; the thermostat controls how hot it gets.

- Weekends: 8:00-11:00, 18:00-23:00 (8 hours)
Mechanical Timer Settings
If using a simple plug-in mechanical timer:
- Push down the segments for times you want ON
- Leave segments up for OFF times
- Each segment typically = 15 minutes
- Set the current time on the dial
- Switch timer to AUTO mode
Mechanical Timer Limitation
Mechanical timers repeat the same schedule every day. For different weekday/weekend schedules, you'll need a digital timer.
Energy-Saving Timer Tips
- Pre-heat time: Towel rails take 30-45 mins to warm up - start timer 30 mins before you need warm towels
- Don't overheat: Set thermostat to 50-55°C, not maximum
- Use boost sparingly: Override for guests, not daily
- Seasonal adjustment: Reduce heating periods in summer
- Holiday mode: Switch off completely when away
Common Timer Problems & Fixes
Timer Not Switching On
- Check current time is set correctly
- Ensure timer is in AUTO mode, not OFF
- Verify program was saved properly
- Check fuse in timer plug
Timer Loses Time
- Replace battery in digital timers
- After power cuts, mechanical timers need resetting
- Some digital timers have battery backup - check if installed
Towel Rail Doesn't Heat Despite Timer On
- Timer controls power, thermostat controls heating
- Check thermostat is turned up
- Room may be at target temperature already

FAQs
Should I turn my towel rail off at night?
Yes, there's no need to heat towels overnight. Set your timer to switch off after evening use (around 10-11pm) and back on before you wake up.
Can I use the boost button with a timer?
Yes, boost typically overrides the timer temporarily (1-2 hours). The timer will resume normal schedule afterwards.
What's the minimum useful heating period?
At least 1 hour for towels to warm through. For room heating, 2+ hours recommended. Very short periods waste energy on warm-up without benefit.
Do I need a timer if I have a thermostat?
Yes! A thermostat controls temperature, but without a timer the towel rail draws power 24/7 to maintain that temperature. Use both for best efficiency.
