    Attach the WLM3 master to a suitable wall. It will generally be convenient if the unit is situated within 0.8 m of the manifold, as most thermal actuators are supplied with 1 m cable. Cables can be run across the surface to the terminals using either the cable releases in the cover or by pressing out the cable entries in the lower part of the cover.

    The voltage of the thermal actuators, 230V or 24V, must correspond that of the master. WLM3-xBA masters are for 230V thermal actuators, while WLM3-xFSmasters/add-on modules are for 24V thermal actuators. Up to 8 different zones can be controlled by the master. Connect the thermal actuator(s) on the loop(s) for each zone to the corresponding terminals on the master.

    • T he next numerical output on the WLM3 master MUST be used for the secondary/boost function. • When the system is in cooling mode, 2-step control will be disabled. • The 2-step controller is available in wired or wireless version. NOTE: To avoid overloading the WLM3 master, we recommend that the secondary output is used as a signalling function for a remote relay.

  • Page 24: Guidelines And Special Features

    When the masters acting as network slaves are in install mode (DIP-1 is ON), their power LED will flash briefly whenever communication is detected (approx. every 3 sec). The WLM3-xFS network master features a menu option that allows the number of network slaves present on the system, and whether there are any errors, to be checked.
