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

transmit signal upon activation, it can be controlled manually or remotely.



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.



Key Lock Function

Press and hold both the Auto/Manual button and the button for 3 seconds to enable key lock function.

If successful the LCD will display the symbol. All keys and Control Knob actions will not respond. If

you wish to cancel key lock function, please press and hold both the Auto/Manual button and button for

3 seconds likewise.



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.
