External Humidistat Option
The Free Star has the option of using an external humidistat remotely
mounted within a room, where available.
In the control box there is a connector that can be wired to, which will
enable the use of an external humidistat. The following steps should be
carried out to enable correct operation of the external humidistat.
• Locate the control box and remove the cover, keeping screws for re-
attachment
• Locate the connector within the control box and remove the plug from the
socket
• Dismantle the plug and remove the link wire from terminals 2 & 3
• Wire remote humidistat to terminals 1 & 3, ensuring wires pass through
the plug back shell
• Re-assemble the plug and refit to the socket on the control box
• The Free Star internal humidistat will now be by-passed and the external
humidistat will control the unit.
