Introduction
Operating Panel General
This Setup module is fitted with an LCD display. The adjuster is supplied in
an aesthetically pleasing, compact 3” by 3 ¼” plastic enclosure. The unit
provides for the commissioning and configuration of Titus MLM controllers.
The unit is plugged into any open RJ12 socket provided on the set of
diffusers connected to a power pack. One RJ12 socket is available on the
back of the diffuser tile on the MLM connection box and the other RJ12
socket is available in the trim of the diffuser on the MLM interface board.

Important Rules
On commissioning a set of diffusers with the Setup Module the
following important rules must be adhered to:
•Per temperature control zone, one MLM wall-stat is allowed for. Thus
if there are fifteen diffusers connected to a power pack controlling
three zones, a maximum of three wall-stats and/or three analog
modules is allowed, one of each per control zone.
•To set up the control zones, the Setup Module can be connected to
any RJ12 socket on that set of diffusers connected to a power pack –
it does not have to be plugged in at the zone being set up. The Setup
Module can be plugged in while the system is powered up, without
resetting the controls.
•To change or select any parameter barring the selection of control
zones, the Setup Module must be plugged into a diffuser in that
particular control zone. It is therefore important to first select the
diffusers for a control zone or be sure it has been selected previously,
before changing any other parameter.
•- By factory default each wall-stat and each analog module has the
setpoint, room temperature and CO functions selected. Thus should
the installation consist of only a wall-stat or an analog module per
control zone, the configuration in above is not required.
•The information changes are periodic and some patience is required
while parameters are being exchanged.
•Changing parameters is non-volatile and once selected and accepted
by the system will be permanently stored.
