PWM control is a relatively accurate adjustment, if you choose the appropriate cycle, the
temperature overshoot will not be very big, a simple low cost common switch valve actuator can be
used .It can be used to control ordinary switch valve of the fan coil , electric valve or KNX valve driver.
3.5 threshold function
Temperature and humidity each provides two threshold functions, the Thermostat ,based on
threshold range of the current temperature and humidity , triggers two different types (1bit / 1 byte) of
data to sent to the bus, which can control other equipment switches or adjust related output of valves.
3.6 logical function
Thermostat provides two logic functions, each has three inputs, each input can be arbitrarily set, it
can be the message (1bit) sent by the temperature threshold , or the message (1bit) sent by the humidity
threshold , or the message received from the bus, also it can be obtained by getting the opposite
message to participate in the logic operation, the message (1 bit / 1 byte) will be output according to the
result , triggering the switch of other equipment, or to adjust output of valves.
3.7 disable/enable temperature and humidity control function, the threshold value
and the logical function
The temperature and humidity control functions can be prohibited or enabled by bus, when the
temperature/humidity function is banned, the Thermostat will not be able to send the control values. The
threshold value and the logical function can also be banned or enabled by bus, when the threshold
function is banned, the Thermostat will not determine the current threshold values range of temperature
