The persistence of clock unit internal clocking.The power down of this intelligent controlling device keeps power supply to use 3.6V chargeable lithium cells,
Under clock unit normal operation, trickle current charging can be carried out to the power down holding unit.
Push-button unit, as the input block of parameter setting, is made up of three key switches altogether, all of parameter setting
The various combination for having these three buttons is completed.The function of possessing by push-button unit：Display parameters, into parameter setting,
Confirm parameter setting, shifting function, numeral Jia one at cursor flashes, numeral subtracts one, exits at cursor flashes
Put, exit and preserve parameter setting.
The unit that display module is intelligent controlling device to be interacted with user.If being in the case where ＆ burning patterns are arranged
Display module is connect in multiplex interface and without any operation, then NULI character on display module, enters display parameters function by button,
The time that current real-time time and set central air conditioning fan coil unit close is shown on display module then；By button,
During into parameter setting, light rotating savings is in the highlighted flicker of the first character bit, after confirming parameter setting or carrying out shifting function, light
Mark is displaced to highlighted flicker at next character for needing and arranging；After all characters all confirm, cursor highlight flicker disappears；Move back
Go out parameter setting or exit and preserve parameter setting, display module NULI character.
Mode switch module, as the operating block that intelligent controlling device difference in functionality is realized, altogether two grades of patterns.One grade is
Plant running pattern, in this mode, intelligent controlling device is connected with temperature controller, realizes the control to central air conditioning fan coil unit
System；To arrange ＆ burning patterns, the set of modes both of which, one kind is parameter setting mode to another shelves, and another kind of is burning mould
Formula, this both of which share one grade.Therefore mode switch module can be suitable for operation, three kinds of feelings of parameter setting and burning program
Shape.
