Have 3 zone heating with EpH controls. Hot water and downstairs works fine. We've set thermostats too high on purpose as don't want them turning on automatically.
However, upstairs, zone 3, is not coming on, the valve to call the boiler is not opening when Boost is pressed.

Is there a way to manually override this?
Do I need a plumber or an electrician? Thanks!

When I press the reset on the RF1A receiver it just goes back solid red. There's no flashing blue light on the system button.
