The user interfaces on the boiler control panel include a double pole on/off switch, 4Nr membrane
button switches with click response, an LCD display screen with backlight and a mechanical dial type
pressure gauge to indicate heating system water pressure.
The membrane button switches (with the exception of the test button) are multi-function and have
varying operation depending upon the operational mode of the boiler.
When requiring to use the membrane button switches, light but firm finger pressure must be exerted
on the appropriate circular marking until a click response is felt/heard.
