    Changing the temperature setting on a WLM 3-xFS master also changes the default temperature for all connected room sensors. However, the temperature setting of each WLTA3, WLTM3 or WLTD3 room sensor is locally adjustable via its own adjustment knob. With this knob, the temperature setting from the master can be increased or decreased by 4°C for that specific room.
