AUTO. The pump reads the system and sets itself. Nothing to configure.

Three fixed speeds. For when you want it set once and left.

Good to know

Standard 130 mm and 180 mm port to port and standard union sizes, so it usually goes in on the existing pipework. Check the port to port distance and connection size against the old pump before ordering. Automatic night power reduction to 5 W, built in and running on its own rather than a mode you select. Cast iron body, for heating circuits.

TF 95C is the limit, not the working temperature. Do not run the pump near its maximum for long periods, so do not fit it straight after an oil boiler, or on any system where the temperature is not controlled. Glycol up to 30% is fine, more is not. Flush the system before the pump goes in and check it stays clear of debris afterwards. Dirty water and debris are the usual cause of early pump failure.
