Connection

Different models have different electrical terminals. Please wire specific model according to the wiring diagram inside the front

cover.

1. Internal terminal

2. External cable

The internal terminals of the product are connected to the outside facilities through a multi-core external cable.

Different models should have different external cables with different core numbers. Please wire specific model according to

the wiring diagram inside the front cover.

Power cable：Input voltage 110V/220VAC

3. THD/THDV/THPD matched sensors

THD0xx/THDV0xx/THPD0xx has a matched T/RH sensor. The sensor has the same terminals as the THD0xx/ THDV0xx/

THPD0xx. So user can connect the two easily.

THPD0xx also has a matched differential pressure sensor, 4-20ma (2 wires)/0-125Pa (accuracy, ±1Pa). It should connect to

the inside terminal AIN3 with power supply connected to EXC+ (+24V) and the jumper of J13setted to mA position.

4. External universal input signal (default 4~20mA)

External universal input signals use AIN1/2 for THD/THDV and AIN1/2/3 for THPD respectively, J11/12/13 should be at the

Power 24V

If the factory default value is changed, the corresponding parameters such as the parameters in P111, P112, and P113, need

to be modified. See the user instruction for details.

5. MODBUS/RS485 communication

RS485 communication inputs/outputs use terminals A/B/GND and the 120Ω terminal resistance jumper J8.

RS485 interface can be networked with other devices, and can also be used to modify the product parameters. See the

Modbus RTU/RS485 communication register address and instructions for details.

6. External universal output signal (default 4~20mA)

External universal output signals use OUT1/2 for THD/THDV and OUT1/2/3 for THPD respectively, J1/2/3 should be at the

mA position for 4-20mA signals and at the Vo position for 0-10V signals.

If the factory default value is changed, the corresponding parameters such as the parameters in P091, P092, and P093, need

to be modified. See the user instruction for details.

Installation

●The product is limited to install in indoor environment for wall mount or from the ceiling.

●It has been calibrated in factory. Install the T/RH and pressure sensor away from the screen with the cable downward.

Sensors must be far away from frequent human activity area and source of cold, heat, humidity and air-condition outlet. And

make sure the ventilation of the sensor is good. Please note that the displays are temperature, humidity or pressure at the

location of sensors, not the location of screen. Therefore suitable location of the sensor box is important for using the product

correctly.

●Temperature and humidity sensor cable or pressure sensor cable is 1.5m long preinstalled in factory. It’s not recommended to

extend the cables. But if necessary, user can extend the cables no more than 10m long following connection guideline while

power off the product.

●The product will work normally and steadily after power on about 30s.

●At the side frame of the screen, there are 3 buttons used for parameters setting and calibration. Although the product has

been calibrated in factory, if necessary, the calibration can be operated by experience customer following operating guideline.

●After long period of working, the sensor perhaps will have little drift. User should re-calibrate the sensor in every one or two

years.

●Standard manometer is needed to calibrate the sensor. The manometers must be within warranty period and have high

accuracy (better than 1.0%RH, 0.15℃and 0.25Pa). Otherwise calibration should be invalid. If standard manometers are not

available, we recommend user to replace new sensors. User doesn’t need to re-calibrate these new sensors after replacing old

ones in field. This feature is one of the advantages of the product that other traditional products cannot offer.

Warranty

Device has limited warranty for 18 months

Wrong Inspection Domain

In the mode of Modbus RTU, message starting with a silent interval of at least 3.5 character times implemented as a multiple of

character times at the baud rate being used on the network (indicated as above).The first field transmitted is the device

address. The allowable characters transmitted for all fields are hexadecimal values 0-9, A-F. Following the last character

transmitted, a similar silent interval of 3.5 character times marks the end of the message and a new message can begin after

this interval.

Modbus Address

The Modbus RTU message frame first field is the device address. Valid addresses are from 0-255. A networked device

continuously monitors the network, including the silent intervals, and when the first field is received (the address) after a silent

interval of at least 3.5 character times, the device decodes it to determine if it is the addressed device.

Slave address can be setting with compatible Modbus RTU software. Default address = 1, suggested 1-32.

Modbus Function

The function code field of the message frame contains 8 binary bits (in RTU Mode) which tells the slave what kind of action to

take. Valid function codes are from 0-127 ( 01H~7FH ). See the relevant Modbus standard.

products support 03H/06H function codes. Appendix is the register address table. Or refer specific product instructions.
