Secure SSR 302 User And Installation Instructions Manual

SSR 302

User and Installation Instructions

Two channel 3 Amp switch (Rx) – Z-Wave

2

The SSR 302 is a 2-Zone receiver and although it

forms part of Secure’s central heating control system,

it can also be operated by third party controllers

which support ‘Thermostat Mode SET’ commands or

‘Binary Switch SET’ commands.

This SSR 302 will act as a repeater once added into
the Z-Wave network, providing an alternative
communication route for units which otherwise would
not be within communication distance of each other.
The Secure SSR 302 forms part of a Z-Wave PlusTM
home automation network.

This document provides information specific to the Z­Wave technology implemented, to ensure
interoperability between SSR 302 and other Z-Wave
products.

Fitting the Receiver

Installation and connection of the receiver should
only be carried out by a suitably qualified person.
WARNING: ISOLATE MAINS SUPPLY BEFORE
COMMENCING INSTALLATION

To remove the backplate from the receiver, undo the
two retaining screws located on the underside; the
backplate should now be easily removed. Once the
backplate has been removed from the packaging,
ensure the receiver is re-sealed to prevent damage
from dust, debris etc.

The backplate should be fitted with the wiring terminals
at the top and in a position which allows a total
clearance of at least 50mm around the receiver.

Direct Wall Mounting

The receiver should ideally be
located near an existing power
supply within an easy wiring
location to the items being
switched. Offer the plate to the
wall in the position where the receiver is to be mounted,
remembering that the backplate fits to the left hand side
of the receiver. Mark the fixing positions through the
slots in the backplate, drill and plug the wall, then
secure the plate in position. The slots in the backplate
will compensate for any misalignment of the fixings.

6

Wiring Box Mounting

The receiver backplate may be fitted directly onto a
single gang steel flush wiring box complying to BS4662
using two M3.5 screws. The receiver is suitable for
mounting on a flat surface only. It must not be
positioned on an unearthed metal surface.

Electrical Connections

All necessary electrical connections should now be
made. Flush wiring can enter from the rear through the
aperture in the backplate. Surface wiring can only enter
from beneath the receiver and must be securely
clamped.

The mains supply terminals are intended to be
connected to the supply by means of fixed wiring.

The receiver is mains powered and requires a 3 amp
fused spur. The recommended cable sizes are 1.0mm2
or 1.5mm2

The receiver is double insulated and does not require
an earth connection although an earth connection
block is provided on the back plate for terminating any
cable earth conductors. Earth continuity must be
maintained and all bare earth conductors must be
sleeved. Ensure that no conductors are left protruding
outside the central space enclosed by the backplate.

7

Internal Wiring Diagram

The SSR 302 has an
integral connection which
makes it suitable for mains
voltage applications
only. No additional linking
is required between
terminals.

Please ensure that all installations comply with the
current regulations.

Fitting the Receiver

If surface wiring has been used,
remove the knockout/insert
from the bottom thermostat to
accommodate it.

Fit the receiver to the backplate,
ensure the lugs on the
backplate engage with the slots
on the receiver.

Swing the bottom of the
receiver into position ensuring
that the connection pins on the
back of the unit locate into the
terminal slots in the backplate.

Adding to a 3rd Party Controller

To add the unit to a 3rd party controller follow these
steps, also known as ‘inclusion’ in Z-Wave terminology.



Ensure the LED is flashing RED on the SSR 302, if
not follow the steps in ‘Remove from a network’ first.



Put the 3rd party controller into inclusion mode.



Press and hold both white buttons on the SSR 302
until the LED starts flashing green.



The SSR 302 has been added onto the network and
the LED will go solid amber.

NOTE: If the LED does not flash green, the add process
has been unsuccessful.

Removing from a Network

To remove from a Z-Wave network, follow the steps
below, also known as ‘exclusion’ in Z-Wave
terminology.



Put the 3rd party controller into exclusion mode.



Press and hold the two white buttons on the SSR 302.



The SSR 302 has been removed from the network
when the LED starts flashing red.

NOTE: If the Network LED does not flash, the remove
process has been unsuccessful.

Node Information Frame - NIF

Pressing and holding the two white buttons for 1 second
will trigger the SSR 302 to issue a Node Information
Frame and enter Classic learn mode for 2s and then in
NWI(Network Wide Inclusion) learn mode. This is useful
when associating / disassociating the SSR 302 with a
control group or just to determine the device and
command classes supported. This can be done at any
time but will not provide any indication to the operator.

End Point Capability Reports

The unit supports two static end points for the two
channels.

Pressing the Top White button for 1 second will issue an
‘end point capability report’ for Zone 1.

Pressing the Bottom White button for 1 second will
issue an ‘end point capability report’ for Zone 2.

Broadcasting in this manner has been implemented to
support association of a channel with a 3rd party
controller that supports Multi-Channel Command
Class.

Note: This product can be included and operated in any
Z-Wave network with other Z-Wave certified devices
from other manufacturers and/or other applications. All
non-battery operated nodes within the network will act
as repeaters regardless of vendor to increase reliability
of the network.
