Installing the base unit
Placement
• Position the base unit just above the manifold, ensuring
24 VAC, 50 VA power is available.
• Check that the cover of the base unit can be easily removed.
• Check that connectors and switches are easily accessible.
Modular placement
The base unit is designed with the option of modular
placement in mind. This means that all major parts are
detachable and can be placed separately (some extra
wiring may be required depending on placement).
Attaching and detaching components
The components can either snap on or off without having
to remove the covers.
Caution: Be sure to attach the expansion module
by snapping it into place via the connection pins on
the module.
Important! Wires between transformers and
base unit must be disconnected prior to detaching
the transformer.
