Hot water always on

Bacteria prevention is turned off and hot water turned off but still 240v on number 6 terminal calling for hot water?

Thanks for reaching out here @Robtla . I would be happy to try and assist.

Just to check, is this a new installation?

How many LED lights do you see on the Heat Link?

Do you see any kind of water drop icon on the thermostat display under the set temperature?

Does it state that the hot water schedule is inactive in the Nest app?

Hi there! Can you tell me what color the LEDs from the Heat Link are? Also do you see any icons on the thermostat display?

The LED light is green on the heat link (single green). The thermostat display appears with al the usual icons, with the hot water setting OFF. The hot water schedule is off, but the booster heater seems to be hot/permanently on at the water tank.
