Wiring

From (Grant) Combi boiler:

• L (brown) to L
• N (blue) to N
• Switched CH-On (green/yellow!) to 4

SSR302 internal electronics provide permanent Live (L) to switched outputs (1, 2, 3, 4).

Switched outputs are:

• 1: Z2 OFF (active high)
• 2: Z1 OFF (active high)
• 3: Z2 ON
• 4: Z1 ON

Observations:

• the SSR-302 zones are swapped (1&3 is Z2, 2&4 is Z1)
• SCS-317 only operates Z1.
• No external link between L and 2 should be used - unlike in the ASR-ZW
