Vogue and Vogue Max share this fascia: colour screen on the left, two knobs on the right, four round buttons under the screen.
- The upper knob with the radiator symbol is heating flow. Leave the lower tap knob if you only came to lower the heating.
- Turn it towards off to lower the flow, or towards max to raise it. Typical range is about 30°C to 80°C.
- Stop around 55°C if the house still warms. Add time on the programmer if rooms take longer to come up.
Look up your exact model on Boiler Manuals if the fascia does not match. Then return to the Ideal flow-temperature page or the Boiler Optimiser.
