Mounting and installation instruction
◆Notice the power supply of the monitor is 24VAC/VDC. Do not connect higher voltages than marked on the
transmitter/controller. Always turn off power before taking following steps.
◆Open the cover: push both clips at the bottom of the unit to remove the front cover from the back cover. Please
operate gently to avoid damaging of the clips.
◆Fix back cover: fix the back cover on the wall according to the dimension and position, see Fig. 1.
◆Connect wires: connect wires according to Fig.2 and press the wires under the terminals of back cover.
◆Close the cover: align the top clip of the unit firstly, then close the front cover and back cover by pressing the bottom
clips, to finish the installation.

TFT Display & Buttons
The front cover contains a TFT screen and 4 function keys: SET, ▲, ▼, and .
➢ Power: be used to turn on/off the transmitter/controller. When turning off, “OFF” will be displayed on the right
bottom corner, and in this situation all outputs are ineffective.
➢TFT display: CO2 and temperature readings will be displayed on first and second line. If the output is linear,
when any key among SET, ▲, and ▼ is pressed, it will display “Linear” on the screen and the keys are
in-effective, see above Fig. 3. The CO2 3-color indication will follow below (default) alarm setpoints. Setpoints
can be adjusted via Advanced Setup parameters P8 & P9.
│ Green: CO2 < 800ppm │ Yellow: 800ppm ≤ CO2 < 1200ppm │ Red: CO2 ≥ 1200ppm │
➢SET button: be used to adjust CO2 PID/relay1 setpoint, temp. PID/relay2 setpoint, humi. PID/relay3 setpoint and
temp. control mode (heating/cooling). Press SET button continuously to walk through parameters quickly.
➢▲ & ▼: be used to adjust the setpoint value. Press the button continuously to walk through setpoint value quickly
➢Lock/Unlock the buttons: Please refer to Advanced Parameter P72.
Analog Output Setting
The default analog output is PID before leaving factory, unless otherwise stated by customers. End user can reset the
analog output to linear by Advanced Setup P20 according to below table 1. Voltage output or current output can be
selected by connecting/disconnecting the jumpers, as shown in table 2.

Manual control
ON1- OFF
Manual control
ON1 -ON
For example, end user may set the CO2 relay offset by Advanced Setup parameters P16. The relay 1 auto control
logic is as explained below:
a. in decrease CO2 mode, when CO2 measuring > CO2 setpoint, relay 1 = ON, when CO2 measuring ≤ CO2 setpoint
– CO2 offset, relay 1 = OFF
b. in increase CO2 mode, when CO2 measuring < CO2 setpoint, relay 1 = ON, when CO2 measuring ≥ CO2 setpoint
+ CO2 offset, relay 1 = OFF
c. under CO2 manual control-OFF, relay 2 = OFF
d. under CO2 manual control-ON, relay 2 = ON
Advanced Setup
Switch off power and remove the back cover, there is a set of DIPs on the middle part of PCB. Switch DIP1 to ON to
enter Advanced Setup interface. Use SET button to switch the parameter items from P1 to P77, and using ▲ & ▼
buttons to adjust the target values. Switch DIP1 back to OFF for normal using.
Note: Please read the below parameters firstly. All acknowledges are required before changing the parameters.
After changing the parameters please wait 6 seconds before power off. Or the new settings will not be saved

If there is a need to adjust P61, P62, P63, P64 to run PID self-tuning, it has to be performed in situations that the
controlled device is properly connected and work normally. Or it is difficult to get ideal PID settings.
