Has dephased pulse signal, according to the rotational characteristic of EC11 rotary coding switch, when the first signal output pin exports height
When level, if detecting, the signal of second signal output pin output has rising edge, is judged as EC11 rotary coding switch
It is rotated clockwise；Conversely, if detecting, second signal output pin is defeated when the first signal output pin exports high level
Low level out is then judged as that EC11 rotary coding switch rotates counterclockwise.Further, according to a period of time same in prime direction
Between point detection EC11 rotary coding switch signal output end A and signal output end B level nature, if signal output end A
When for high level, there is a high level in signal output end B, and EC11 rotary coding switch rotates clockwise at this time, together
When, the counter in control module starts counting, when detecting next impulse waveform identical with above-mentioned level nature, meter
Number device adds one, the rotation amplitude of release button unit can be determined according to the variable of counter, namely determine rotary coding switch
Rotate angle.

Phase selection instruction, selection of time instruction, temperature selection instruction etc.；The second control instruction that the control module generates includes mode
Selection instruction, week selection instruction, selection of time instruction, temperature selection instruction etc..
Specifically, the operating process below by way of knob controller is illustrated, as shown in figure 4, being a reality
The structural schematic diagram of knob setting module in example is applied, which includes a knob and four keys, four keys
Go to upper and lower, left and right direction is separately positioned on around knob, four keys be respectively setup key, home key, away key and
Schedule key can enter different menu options by pressing four keys respectively, have " OK " key in the middle part of knob, lead to
Four keys of operation and knob and acknowledgement key are crossed, can be convenient, quickly carry out system parameter setting.The present embodiment passes through rotation
The setting of button (rotary coding switch) and key is divided into four time zones, and by rotation rotary coding switch to different time
Section carries out temperature setting, to control the function having by oneself on temperature control device and keep its more intelligent.
Further, it when carrying out clock setting, is configured by pressing schedule key, is selected by knob or key
It selects week, " OK " key on push-turn key is confirmed；Select to carry out time setting by away after week, equally by knob or
Key selects the time, and " OK " key on push-turn key is confirmed.
By selecting time zone by one of four keys, i.e., daily different time sections, wherein setup key represent early morning,
Rest that schedule key represents work, the representative of away key is gone home, home key represent sleep, pass through knob after pressing corresponding key
The initial time section in each time zone is set.Such as when pressing setup key, rotated clockwise and rotary setting counterclockwise by knob
Beginning and ending time is 5 minutes by each pulse settings that rotary coding switch rotation generates, and presses " OK " button expression later and has set
Finish.The set-up mode in other time zones is identical as above-mentioned setting up procedure.
Setup key may be arranged as temperature multiplexing function, namely carry out temperature setting by setup key.Press setup
