It is a direct replacement for the non-plus variant that I had fitted 10 years ago. I am disappointed that I had to change the pump due to an issue with the inverter control Head. The failurewas that it wouldn’t start to runby a relay driven by a time clock and thermostat, but if you turned the mains power off to it and turned it back on it would run perfectly.
