What it is
The Ferroli ZU0800510 is a 24-hour mechanical timer clock used to control the heating and hot water switching periods on Ferroli Optima series boilers. It is a plug-in mechanical time control that replaces the existing clock unit on the appliance. The timer provides fixed daily on/off switching rather than a digital programmable schedule.
Signs this part needs replacing
- The boiler does not switch on or off at the times set on the dial
- The timer dial does not rotate or advances unevenly
- The clock runs slow, fast or stops altogether
- Heating stays on permanently or never comes on via the timer
- The timer only works when the manual override is used
Before you order
- Confirm your boiler model is a Ferroli Optima 1000 or Optima 900
- Check the GC number on the appliance data badge against your model
- Confirm the existing control is a 24-hour mechanical timer, not a digital programmer
- Check the part number on the existing clock unit where visible
