filling pressure (≥ 14.5 psi = ≥ 1.0 bar).
The system pressure is shown for 10 minutes after
which the standard display returns.
Fault
Burner and boiler circuit pump are not operational.
Frost protection is active up to 2 psi (0.1 bar).
The heating system will only become operational again
if the pressure is back to 14.5 psi (1.0 bar).
