WB-MWAC v.1: legacy model comparison

Selected legacy-model reference linked from the v.2 manual. For installation and configuration of the requested model, use the WB-MWAC v.2 manual.

Identify the hardware first

The older WB-MWAC has six general-purpose inputs labeled S1–S3 and F1–F3, two pulse-counting inputs P1/P2 and two changeover relay outputs K1/K2. Its isolated sensor-supply output iVout is specified as 14 V. Its terminal assignments and sensor-supply specifications must not be substituted for the v.2 instructions.

Pulse counters and leak control

The internal battery maintains pulse counting on P1/P2 when external power is absent. It does not supply the complete module or valve actuators. General-purpose input counters are kept in RAM and reset on power loss; water-meter counters use nonvolatile storage.

The input/output mapping matrix defines responses to leak sensors and buttons. Wet cleaning mode, available from firmware 1.21.0, temporarily suppresses programmed leak actions while continuing to indicate sensor states. When it ends, wet sensors can trigger leak protection again.

Use the software configuration reference together with the manual and register map for your actual hardware version.
