Thermostat mainly send output control value to fan coil actuator through collecting temperature
and setting temperature , so as to realize the effect of indoor constant temperature. Thermostat can also
carry out fan speed adjustment, room mode switching and timing Settings by KNX manual operation ,
and so on. Thermostat also provide 3 binary inputs which can be used to switch, dimming, curtains and
scene control.
3.2 The external and internal temperature sensor
Thermostat can provide three temperature collecting ways,
○
1 from temperature sensor in
Thermostat,
○
2 from bus to receive external temperature,
○
3 from external NTC thermistors.
3.3 Basic heating cooling and additional heating cooling control functions
Thermostat has the basic heating refrigeration output control function according to the temperature
set by the user , in addition to basic heating refrigeration control function, there is additional heating
refrigeration control function as a supplement to the temperature control. When the actual temperature
and set temperature have a large deviation , additional heating refrigeration control function can let a
room faster heating or cooling.
3.4 the temperature control
Thermostat use relative adjustment in all kinds of temperature setting values of work mode .At the
same time ,it also provide a variety of types of controls, such as continuous PI control, switch mode PI
control, 2 - point control and fan coil control, different types of control is suitable for different types of
temperature controller.
Continuous control
Continuous control’s control values is calculated by the actual temperature and set temperature,
and then control the opening of continuous valve, attain the comfortable room temperature state. For
