Grant Vortex Eco outdoor boiler

[Tracywt2]

Hi. I wonder if someone can help me. Our Grant boiler seems to be faulty, it will only work when the test switch is on. Is it safe to operate it like this until we can get a plumber out tomorrow? Many thanks

Without seeing it I would advise no. The test switch is for the engineer to fire the boiler to check various readings and will only go until the control stat is satisfied it overides all the controls in the house

Not really no. The test switch overrides the interlocks and controls.
