2. Operation method:
Normal mode:
Normal mode L1~L6 are status indicators. The digital tube displays the current frequency
conversion setting frequency K1. Press the frequency conversion pulse to output according to
the setting of 51, L1 lights up, press the pulse again to stop, L1 goes out. The variable frequency
pulse voltage is set according to the CN4 jumper of the power board.
K2 presses the fixed frequency control relay to start working, 2 lights up,
presses the relay again to stop working, and 2 goes out.
Press K3 and the fan runs at full speed, L2 lights up, presses the fan again to stop,
and 2 goes out. The wind turbine will start to check the feedback after running for 10s.
If the feedback is abnormal, there will be an E1 prompt.
Press K4 to open the damper and keep it open. Press K3 again to close the damper.
The number of damper steps runs according to the set value (the next section will
explain how to set it in detail). L3 lights up when the air door is working, and when the work ends, B goes out.
Press K5, double solenoid valve control relay 1 will work for 0.5 seconds and then release,
press K5 again, double solenoid valve relay 2 will work for 0.5 and then release, and cycle in turn.
15 lights up within 0.5 seconds of work, and L5 is a two-color indicator to distinguish different relays.
Press K6, the motorized valve will work a set of step angles. The number of steps runs as set
(the next section will explain how to set it in detail).
K7-K9 are invalid in normal mode.
Setting mode:
Entry method: Press and hold the K9 key and then press any of the function keys Kl-K4,
and release the function keys first to enter the corresponding setting mode. Each function
key corresponds to a setting mode of its own function. After entering the setting,
the decimal point on the lower right foot will be flashing.
1. bPU-Maximum frequency conversion 0-2202.tm-timing enable 0-13.
tm-timing on time, 0-999 unit minutes.
4. tfU-Timed off time, 0-999 unit minutes
5. FdU air door step number, 0999, the actual number of steps required for
the air door divided by 10, for example: if the air door is 1750 steps, set it to 175.
6.Ht. Throttle heating wire check enable, 0-1, 0 turns off heating wire check, 1 turns on
heating wire check 7.FU electric valve step base. The number of steps required for an
electric valve to turn an angle. Generally 12,
16, 18.
After entering the setting state, press function keys K1-K6 to select setting options.
Press K9 key to enter this option, press K7 or K8 key to change the value size
(K7K8 can be long-press acceleration setting), press K9 again to return to the option state
or directly press K1-K6 keys to select the next option. After the setting is completed,
long press the K9 key to save the setting and return to the normal state.
Timing mode:
If the timing mode of the corresponding function is set successfully, the L1-L6 lights will be
flashing, and the corresponding load will no longer be controlled by buttons Kl-K6,
but controlled according to the set tnu and tfU parameters.
