Thermostatic Radiator Valve

Thermostatic Radiator Valves (TRVs) sense the air temperature around them and regulate the flow of water through the radiator to which they are fitted. They can be set at a level that gives you the room temperature you want. These settings may have to be different in each room, and you can set the TRVs to suit each room and then leave them to do their job. The device can be set temperature by manual or by gateway and schedules are created by gateway. This product can be operated in any Z-Wave network with other Z-Wave certified devices from other manufacturers. All mains operated nodes within the network will act as repeaters regardless of vendor to increase the reliability of the network.

Installation

Mounting
Do not insert the batteries yet.

Remove any existing control from the radiator valve
Mount the TRV on the valve and tighten it by turning the Valve cap clockwise.
You may need to use one of the adaptors supplied to fit your radiator valve:

4. The TRV can be mounted at various orientations as shown below:

Note: The TRV needs a free flow of air to sense the temperature so they must not be covered by curtains or blocked by furniture

Calibration

The unit supports the SmartStart function, SmartStart enabled products can be added into a Z-Wave network by scanning the Z-Wave QR Code present on the product with a controller providing SmartStart inclusion. No further action is required and the SmartStart product will be added automatically within 10 minutes of being switched on in the network vicinity.
After finishing inclusion, the unit will start initializing itself. During this period the LCD will display INIL with backlight flashing for 2 minutes.
When the TRV displays ADAP, press the UP button to start the calibration. The number 0 will change to number 1. If it does not change to 1, press the UP button again.
The TRV will start to adapt itself to the stroke of the valve’s body by opening and closing the valve twice to store the endpoints. This could take up to 1 minute.
Calibration is complete when temperature readings appear on the LCD.
Note: Temperature readings will become accurate 10 minutes after installing the batteries.

Operation

The user can choose between two heat levels for automatic temperature control without user intervention. This can be selected either by button M or set through the gateway.
“HEAT” mode: This is a higher temperature level for indoor comfort and is normally used when a room is occupied.
“ENERGY HEAT” mode: This is the lower temperature level for energy saving, typically used during sleeping or when a room is empty. Setpoints for these two modes must first be preset through the gateway. The TRV will activate heating whenever room temperature falls below these setpoints.
Users can use the gateway’s scheduler or scenes controller to switch between these two modes at any time depending on their lifestyle. Refer to the gateway’s instruction manual for this.
Manual Over-ride: the user can override the preset settings at any time allowing for on-demand manual control of the TRV. Pressing the Up, Down, and M buttons on the TRV will bypass the setpoints temporarily for 4 hours (Configure 10). After 4 hours, it will restore the last mode and temperature.
Open window detection: When enabled, the TRV will automatically stop heating when it detects a sudden drop in room temperature (default: 2°C in 15 minutes). This usually happens when a window or door is opened without turning off the heating device. The LCD will display OP. The device will return to the previous mode of operation after 30mins or press any button to exit.
Keylock: When enabled, the button keys on the TRV will be locked to prevent any tampering, shown by the LOCK icon on the LCD. A key lock can also be activated by pressing and holding buttons P and M simultaneously for 5 seconds.
OFF: This mode turns off the thermostat control of the TRV. Note that this does not switch off the device itself.

Maintenance

Low Battery: Under low battery conditions, the TRV will remit RF signals to the gateway to alert the user of its low battery condition. Replace the batteries as soon as possible.

Decals: When the TRV is inactive for long periods in use, e.g. during summer, it will automatically rotate the valve once every two weeks. This helps to prevent clogging of the radiator pipes and stiffening of the valve caused by a build-up of minerals.

Programming Z-Wave Group

The TRV supports1 Association Group: Group 1: Association with 1 Controller node.
Group 1 command:

When the unit is powered up the first time, the unit will send a Notification Report and Clock report to the node of Group 1.
When the battery level of the unit drops to an unacceptable level, the unit will emit a Battery report to the nodes of Group 1.
When performing Factory Reset the unit will send Device Reset Locally Notification to the node of Group1.
The unit will send Sensor Multilevel Report to the node of Group 1 every two hours.
When changing mod of the unit, it will send Thermostat Mode Report to the node of Group 1.
When changing the target value of temperature, the unit will send Thermostat Setpoint Report to the node of Group 1.
When changing the state of the button lock, the unit will send Protection Report to the node of Group

Troubleshooting

The table below lists the several steps involved when adding or removing the TRV from the Z-Wave network.

Action/Status	Description	Rings around the LCD display
No node ID	The Z-Wave Controller does not allocate a node ID to the unit.	Blinks 2-second on, 2-second off for 2 minutes
Auto Inclusion	The power is applied for the first time and no node ID has been stored in the module, or after executing reset.
Manual Inclusion	1. Put the Z-Wave Controller into inclusion mode.
Manual Inclusion	2. Press the P button 3 times within 1.5 seconds to put the unit into inclusion mode.
Exclusion	1. Put the Z-Wave Controller into exclusion mode.
Exclusion	2. Press the P button 3 times within 1.5 seconds to put the unit into exclusion mode.
Factory Reset (This procedure should only be used when the controller is inoperable.)	1. Press the P button 3 times within 1.5 seconds to put the unit into exclusion mode.
	2. Within 1 second of step 1, press the button P again and hold for 5 seconds.
	3. Node ID is excluded. The device reverts to the factory default state.	2-second on, 2-second off For 2 minutes

 Failed or successful results in including/excluding the ID can be viewed on the Z-Wave Controller.

Note: If you are connecting this unit to a Z-wave Controller that utilizes the S2 security protocol, you may be asked by your controller to enter a 5 digit Device Specific Key (DSK) that is unique to each unit. This can be found in one of two places: – on the QR code label on the back of the unit – on the insert card inside the packaging

The table below lists typical problems encountered:

Symptom	Possible Cause	Recommendation
Cannot work	The battery is not fitted properly or run out of battery power.	Check if batteries are fitted or replace a new battery.
RF Reset	The battery voltage is too low.	To make the device boost normally, the battery voltage must be DC2.8V.
Cannot carry out inclusion and association	The device has been paired to other Z-Wave controller.	1. Perform Exclusion from another controller first, then carry out inclusion with the new controller. 2. Perform Factory Reset on the device and then carry out Inclusion with the new controller
Cannot carry out inclusion and association	The device is out of range.	1. Relocate the controller closer to the unit. 2. Install a Z-Wave repeater such as smart plugs or other AC devices that can operate as a Repeater.
