What it is
The Vokera CN9 water pressure switch and cylinder stat, part number 20040984, is a combined control component used on Vokera Verve System 47KW boilers. It monitors water pressure in the heating circuit and provides cylinder temperature control signalling to the appliance. It is supplied as a switch assembly for service and repair work.
Signs this part needs replacing
- The boiler locks out or fails to fire when system pressure is correct
- The pressure gauge reads normal but the appliance behaves as though pressure is low
- Cylinder hot water runs consistently hotter or cooler than the set temperature
- Intermittent faults that clear when the switch or its wiring is disturbed
- Fault indications relating to water pressure or cylinder temperature
Before you order
- Confirm the appliance is a Vokera Verve System 47KW
- Check the fitted component reference CN9 and part number 20040984 against the part being replaced
- Verify the fault lies with the switch rather than the wiring or system pressure
- Isolate and depressurise the boiler before fitting
