1. Summary

Thermostat is a device to control indoor temperature. It adjusts the room temperature and relative

humidity according to the measured temperature and relative humidity, generally implemented by

controlling indoor temperature controller and fan coil actuator on the bus. Thermostat closely bound up

with our living environment. For example, in an air-conditioned room, people would feel comfortable only

the room temperature and relative humidity is under in a certain range. Then we can monitor the current

actual indoor temperature, relative humidity through the panel, if it is beyond control, the Thermostat will

send a signal to adjust the indoor temperature and humidity by air condition. It is also widely applied in

other industries, such as food industry, temperature and humidity are essential, greenhouse and other

humidity-related industries.

User can adjust the indoor temperature according to their needs by capacitive touch buttons. LCD

screen displays the status of the current temperature control.

This user manual provides specific technical information including installation and programming

details, and explains how to use the binary input by the application examples.

1.1 Product and function instruction

Temperature control panel mainly used in building control systems and installed with EIB / KNX bus

and other devices together as a system. It’s connected directly to the terminal via the EIB bus, needed of

additional power supply. Standard 86 wall-mounted installation. You can use the engineering design

software ETS (version above ETS3 ) with VD4 ETS files to allocate physical address and set up

Parameter.

Main function summarized as below:



Capacitive touch buttons, LCD display



Selected internal and external temperature sensor



Basic and additional heating and cooling temperature control function



Relative and absolute room temperature adjustment function



Variety of temperature control mode, continuous PI control, switching PI control and
