i have the above pump fitted on my heating system but the display is now reading 1 and doesnt seem to be circulating the water.

can anyone help??

Turn it up.

it normally displays the wattage its using, normally 20 something, but now it just says "1" wherever the dial is

Even though the pump has auto air bleed there may be air elsewhere in the system and if so would render the auto bleed useless as a function until water feed or supply is re-introduced and allowed to prime the pump and system. I would check this first before attempting other solutions.

The integrated Led light should climb well above 1 (delivery head) in commissioning mode.
