Inconvenient
Radiator does not cool off.
Solution
• Check if thermostatic head has been properly installed.
• Check that no foreign objects (dirt particle, a.s.o.) have been
entering on the thermostatic valve seat. To verify it, take out
the thermostat head from valve, and check if the rod of thermo-
static shutter moves freely or is blocked. In case it is blocked
the full insert thermostatic shutter has to be dismantled and
replaced. Same procedure applies if the gasket of the themo-
static valve has been damaged by foreign objects.
• Check if pressure differential is too high: differentials higher
than 1 bar could bring the valve shutter to an open position and
cause the valve to leak.
Inconvenient
Noise or jamming.
Solution
• Check that inlet and outlet connection have not been inverted.
• Check that heating system is provided with overpressure valve
(of differential by-pass).
• Check that overpressure valves is correctly installed and cor-
rectly set, valve differential pressure higher than 0.3 bar can
cause noise when in throttling condition.
• Check that pump capacity is adequate to the system (not
too high).
