VT II/MONITOR II ISSUE: station on but valve not on

IMPORTANT: Any time you install or remove components, disconnect power to the unit before you begin. "Hot Plugging" components in this manner can cause even further damage to one or more cabinet components.

Check the 2-Amp fuse within the 24V power supply in the cabinet. Replace as necessary.

Check the voltage with a volt-meter at the terminal block, located in the bottom of the cabinet between the valve common and the station in question. There should be approximately 24V AC between the two. If the voltage is incorrect, the transformer must be replaced.
