MLM Tool occupancy wizard
The MLM Tool rev 8.xx contains a setup wizard (Wizards/Occupancy) that assists the installer to easily set-up or
de-activate occupancy sensing on a zone by zone basis.
MLM24 Tool Occupancy display
The Wallstat and On-board master units each contain an Occupied button to indicate status – green for occu-
pied and red for unoccupied.
The progress bar next to the button is divided into the ‘delay 1’ and ‘delay 2’ areas. As the delay timers run
down, the progress bar will decrement from right to left. Once an unoccupied condition is detected, the bar dis-
play will change from green to red.
The adjacent picture indicates a Wallstat master unit entering the second delay period, with the control disk
moving towards the pre-set minimum of 30%. Once the second delay period has expired, the control disk will
move to 0% position. This position will be maintained until either:
Occupancy is detected and control reverts to normal
or..
The room temperature drifts outside the Backoff band setting with the control disk then moving back to
the 30% position.
