Secure SRT321 Manual page 4

Offer the plate to the wall in the position where the SRT321 is to be mounted and mark the
fixing positions through the slots in the wall plate. Drill and plug the wall, then secure the
plate into position. The slots in the wall plate will compensate for any misalignment of the
fixings. Undo the screws of the base of the thermostat and swing it away from the wallplate.
Place the 2 x AAA batteries correctly into the battery compartment. Complete the installation
by swinging the room thermostat into position by engaging with the lugs at the top of the wall
plate before pushing it carefully into its plug-in terminal block. Tighten the 2 captive screws
on the underside of the unit.
Inclusion/Exclusion
On factory default the device does not belong to any Z-Wave network. The device needs to be
added to an existing wireless network to communicate with the devices of this network.
This process is called Inclusion.
Devices can also be removed from a network. This process is called Exclusion. Both
processes are initiated by the primary controller of the Z-Wave network. This controller is
turned into exclusion respective inclusion mode. Inclusion and Exclusion is then performed
doing a special manual action right on the device.
Inclusion
For including the thermostat as a secondary controller into an existing the Z-Wave network do
the following steps: Bring your primary controller into inclusion mode. Set DIL switch 1 on
the back of the unit to "ON" position, scroll through the function menu by rotating the dial,
select "L". Once the character starts flashing the installer has 60 sec to activate the 3rd party
unit, once the 3rd party unit has been activated the process must be completed within 240 sec
or the thermostat will timeout.
