Waterline add on Module - type WlM3-xao
Each master module is capable of controlling 8 heating zones, each of which may use one or
more loops of piping, with one or more thermal actuators. These zones are referred to as channels
1 to 8. If more than eight zones are to be controlled, it is necessary to install an add-on module
((WLM3-xAO), which provides another six outputs.
The AO module then controls channels 9 to 14 (9-E on the hex encoder).
Connection of master and add-on module
Connect the AO module using the special cable included in the box.
Connect a fused 230V AC mains supply.
The sensor bus can be connected to either the WLM3 master or add-on module, using either bus
(daisy chain) or star connections. Thermal actuators 1-8 are controlled by the WLM3 master while
9-14 are controlled by the add-on module.
important: all lEDs will flash in case of incorrect or lacking connection.
