The Base Unit has two separate compartments for wiring.
1. The Mains Compartment (A) is for incoming mains wiring and
connections from the relays to control devices such as valves
(Figure 5). This compartment should only be accessed by
qualified electricians. Do not open this compartment unless
the mains power is isolated.
2. The Signal Compartment (B) is for low voltage data
connections. This compartment should only be accessed
by competent technicians, though these needn’t be fully
qualified electricians.
