Please refer to the chapters below for detailed information about all aspects of the usage of the product.
What is Z-Wave?
This device is equipped with wireless communication complying to the Z-Wave standard. Z-Wave is the international standard for wireless communication in smart homes and buildings. It is using the frequency of 868.42 MHz to realize a very stable and secure communication. Each message is reconfirmed (two-way communication) and every mains-powered node can act as a repeater for other nodes (meshed network) in case the receiver is not in direct wireless range of the transmitter.
Z-Wave differentiates between Controllers and Slaves. Slaves are either sensors (S) transmitting metered or measured data or actuators (A) capable to execute an action. Controllers are either static mains powered controllers (C) also referred to as gateways or mobile battery-operated remote controls (R). This results in a number of possible communication patterns within a Z-Wave network that are partly or completely supported by a specific device.
There are two different role a controller can have. There is always one single primary controller that is managing the network and including/excluding devices. The controller may have other functions – like control buttons – as well. All other controllers don’t manage the network itself but can control other devices. They are called secondary controllers. The image also shows that its not possible to operate a sensor just from a remote control. Sensors only communicate with static controllers.
The STP328 is a battery-operated wall controller capable of controlling a boiler actuator via a Z-Wave wireless connection. The device can act both as primary controller or as a secondary controller. The controlling and switching behavior however can not be set wirelessly but with local control buttons only. The device has multipe timers and is therefore able to execute even complex heating scenarios.
The STP328 is supplied in two parts. The actuator (SEC_SSR302) which is hard-wired to the combi or conventional system boiler and the thermostat which can be used in any normal domestic environment within a typical 30-metre range without the need for any costly or disruptive wiring.
Batteries
The unit is operated by batteries. Use only batteries of the correct type. Never mix old and new batteries in the same device. Used batteries contain hazardous substances and should not be disposed of with household waste!
Battery Type: 1 * CR2
Thermostat
The backplate of the device is to be used as a mounting plate for wall mounting. Open the backplate by undoing the screws located on the underside and swing open the control panel. Use the backplate as a pattern and mark the drill holes, drill the holes and mount the backplate. The slots in the backplate will compensate for any misalignment of the fixings. Reassemble the control panel with the backplate and swing close it into closed position.
Boiler Actuator
Installation and connection of the receiver should only be carried out by a suitably qualified person.
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 that 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.
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.
Internal Wiring Diagram
The SSR302 has an integral connection which makes it suitable for mains voltage applications only. No additional linking is required between terminals.
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, and 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.
Warning: ISOLATE MAINS SUPPLY BEFORE COMMENCING INSTALLATION!
If the device already belongs to a network, follow the exclusion process before including it in your network. Otherwise, inclusion of this device will fail. If the controller being included was a primary controller, it has to be reset first.
For Inclusion and Exclusion press and hold both white buttons on the device until the LED starts flashing.

Part 1 – Day to Day operation
The Thermostat has been designed to be a simple to use thermostat, requiring minimal user intervention with a pre-programmed heating profile. Simple temperature adjustments can be easily carried out by using the ‘+’ and ‘-‘ buttons. The indicator lights react to any temporary user adjustments, with the LED indicators working in the following way; ‘Warm’ is shown by two red lights and ‘Cool’ is shown by a single blue light. The centre button marked ‘Warm/Cool’ allows you to toggle between the warm and cool settings.
Power Down Mode
During normal operation the Thermostat will go into Power Down Mode, this is to maximise the life of the 3 x AA batteries fitted. Normal operation will continue during this mode, and the heating will be unaffected. The result of the Power Down Mode will mean that the LED indicators will not be displayed and LCD will not be illuminated, although the ‘Warm’ or ‘Cool’ temperature will be displayed. To ‘wake up’ the AS2-RF press the ‘Warm/Cool’ button for 5 seconds, this will then illuminate both the LED and LCD displays for a period. Any adjustment can then be made, the Power Down Mode will commence again approximately 8 seconds after the last button press.
Warm and Cool Temperature Adjustment
The Warm and Cool target temperature settings on the Thermostat are fully adjustable. To change a target temperature it is first necessary to press the centre button to bring up the ‘Warm’ or ‘Cool’ setting (indicated by the red or blue LED indicators). By using the up/down keys under the flap the Warm/Cool temperature can be increased or decreased to the desired temperature setting. PLEASE NOTE – it is not possible to set the warm setting to below that of the cool setting or vice versa. Once a new temperature has been set in either the Warm or Cool setting the Thermostat will continue to use this setting until the next manual adjustment.
Frost Protection
The blue button situated under the flap will initiate the frost protection mode, when pressed the word
‘STANDBY’ will appear on the display, the thermostat has been preprogrammed with a frost protection temperature level of 7°C, this can be adjusted by using the up and down arrow buttons. Minimum setting 5°C. It is not possible to set a frost protection temperature above the cool setting.
The Thermostat has been designed for minimal user intervention, however should any changes to the existing programms be required please press button 6 and 8 simultaneously to enter the programming mode, this will allow you to:
Time and Date Check
The Thermostat has a built in automatic clock adjusting for BST and GMT time changes and has been preset with the current time and date during manufacture. No alteration should be required to the time and date, however if any modification is required please refer to the steps below.
Setting Heating Profiles
The Thermostat contains a selection of five preset and one user definable profile options, one of these will have been set by the Installer. Care should be taken to ensure a profile is selected that suits your lifestyle the best. If none of the preset profiles meet your requirements it is possible to set a user defined profile.
Heating Profiles
The Thermostat has six heating profiles, five are fixed and one is adjustable. Profile ‘ONE’ has been set as the default and is detailed below. During installation, a heating profile should have been set to best match your requirements:
Profiles one to five have fixed periods, no alteration to the Warm/Cool times can be made, if it is necessary to make any alterations then profile six must be used. Profile six will allow you to set up a profile to your exact requirements.
User Definable – 7 Day Programming
Profile 6 will allow you to set up a profile to your exact requirements. By using the flow chart below you can adjust the Warm/Cool timing periods as required. If only one or two Warm/Cool periods are required on any day set the times accordingly and set the remaining Warm and Cool start times to be exactly the same as each other. This will cancel the 2nd or 3rd Warm/Cool periods altogether for the day concerned. Unused periods will be shown by a series of dashes on the settings screen. Press SET and the next day and SET appears in the display. Press SET to adjust the next days settings or EXIT to return to the main menu. To do this press SET until the next day and SET appears in the display. Unused periods will be shown by a series of dashes on the setting screen. If one or two periods have been set and you wish to return to three periods in 24 hours then pressing the up arrow when the dashes appear after the last Cool setting will bring back the hidden Warm/Cool settings.

Boiler Actuator
The unit supports two static endpoints for the two channels.
Pressing the Top White button for 1 second will issue an ‘endpoint capability report’ for channel 1. Pressing the Bottom White button for 1 second will issue an ‘end point capability report’ for channel 2. Additionally the device enters learn mode for 1 second. This is useful when associating/disassociating the device 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
Broadcasting in this manner has been implemented to support the association of a channel with a 3rd party controller that supports Multi-Channel Command Class.
The Node Information Frame is the business card of a Z-Wave device. It contains information about the device type and the technical capabilities. The inclusion and exclusion of the device is confirmed by sending out a Node Information Frame. Beside this it may be needed for certain network operations to send out a Node Information Frame.
Pressing and holding the two white buttons for 1 second will trigger the device to issue a Node Information Frame.
Associations
Z-Wave devices control other Z-Wave devices. The relationship between one device controlling another device is called association. In order to control a different device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called association groups and they are always related to certain events (e.g. button pressed, sensor triggers, …). In case the event happens all devices stored in the respective association group will receive a common wireless command.
Association Groups:
Set and unset associations to actuators
Associations can be assigned and remove either via Z-Wave commands or using the device itself.
