TRV-1ZBS Thermostatic Radiator Valve
Introduction
TRV-1ZBS is a ZigBee Radiator Valve designed to control the surrounding temperature by controlling the flow of
hot water of radiators in the ZigBee network, i.e. indoor room temperatures.
The Radiator Valve utilizes ZigBee technology for wireless signal transmission. ZigBee is a wireless
communication protocol that is reliable and has low power consumption and high transmission efficiency. Based
on the IEEE802.15.4 standard, ZigBee allows a large amount of devices to be included in a network and
coordinated for data exchange and signal transmission.
The Radiator Valve serves as an end device in the ZigBee network. It can be included in the ZigBee network to

automatically through the control panel (please refer to your control panel manual for details).
In the Auto Mode, you can use the same functions as in Manual mode except the Control Knob
Set to ON and OFF function.
Anti-frosting
When the Radiator Valve detects a frosting hazard, it will automatically open the valve for hot water to flow in
order to maintain the temperature and to prevent further frosting.
Anti-calcification
The Radiator Valve will open and close the valve weekly to prevent calcification. During anti-calcification
process the LCD will display a CAL.
The default value for anti-calcification process is 23:00p.m every Saturday.
Boost Function
Press the Boost button to temporarily speed up heating process by further opening the valve. The boost
function lasts 5 minutes (LCD displays: 300 seconds countdown). If you wish to cancel boost function, press
the button again.
Setpoint Offset
The device is usually installed at the corner of the room and near the heating pipe. As a result its
temperature reading may deviate from room temperature at center of room. Use the Setpoint Offset
function to compensate the deviation.
To calculate setpoint offset, simply subtract room temperature with device temperature.
For example: If device temperature is 20°C and room temperature is 18°C, then setpoint offset = 18 – 20 =
-2°C.
After setpoint offset is applied, the device will operate according to adjusted temperature.
For example: If device temperature reading is 20°C, setpoint offset is -2°C, the device will operate using
18°C as actual reference.
To program Setpoint Offset:
1. Press and hold the button for 3 seconds to enter offset adjustment.
2. Rotate the Control Knob to desired offset temperature.
3. Press any key to finish and exit offset adjustment.
Open Window
If Radiator Valve detects indoor temperature drops rapidly by opening the window, the Radiator Valve will
activate Open Window function by partly closing the valve to reduce temperature setting for 15 minutes. The
LCD will display symbol, the device will check the temperature every minute. After 15 minutes, the
Radiator Valve will return to the set temperature with valve opening again, Open Window Function closes.
Control Knob
Rotate the Control Knob to adjust the temperature, rotate clockwise to reduce temperature and
anti-clockwise to increase the temperature. The adjustable temperature range is 5°C to 30°C. If you rotate
the Control Knob over 30°C to ON, after 1 minute, the Radiator Valve will open the valve completely, to
preserve battery power. If you rotate the Control Knob lower than 5°C to OFF, after 1 minute, the Radiator
Valve will close the valve completely. To disable ON/Off status please rotate the control knob or press
button.
ON: When turned to ON, the valve is opened completely. This function is used to preserver battery life
during summer, when heating is not required. Do not use this function in winter when heater is activated,
otherwise the room temperature will rise uncontrolled.
OFF: When turn to OFF, the valve is closed completely. This function is used when heater is activated but
heating is not required in a room with no occupants.

Zig-Bee Network Setup and Installation
ZigBee Device Guideline
ZigBee is a wireless communication protocol that is reliable and has low power consumption and high
transmission efficiency. Based on IEEE802.15.4 standard, ZigBee allows a large amount of devices to be
included in a network and coordinated for data exchange and signal transmission.
Due to the fundamental structure of ZigBee network, ZigBee device will actively seek and join network after
powering on. Since performing a task in connecting network may consume some power, it is required to
follow the instructions to avoid draining battery of a ZigBee device.
- Ensure your ZigBee network router or coordinator is powered on before inserting battery into ZigBee device.
- Ensure the ZigBee network router or coordinator is powered on and within range while a ZigBee device is in
use.
- Do not remove a ZigBee device from the ZigBee network router or coordinator without removing the battery
from a ZigBee device.
