Question: When does the MQ switch off?


The flow switch only causes the MQ to switch off automatically during normal operation if the flow rate drops below 0.07 m³/h. If the flow rate drops below the required level, the pump switches off after 12-15 seconds. It is also possible to switch the pump off manually using the ON/OFF switch.

The MQ also switches off after an overtemperature alarm or dry running alarm triggers.
