Operation

Set Set-Point

 

Press〖SET〗key to enter into the set status. The current set-point value displays.
Press〖+〗or〖-〗to set the value (keeping depressed can fast set).
Press〖SET〗to exit, and save the settings.
The status will exit, and the setting will be saved, if no key operation within 10 seconds.
Factory default setting is 28.0℃.

Set System Parameters

Keep〖SET〗depressed for 5 seconds to enter into parameter setting status.
Press〖+〗or〖-〗to select the parameter code (see parameter code table below).
Press〖SET〗to display the value of the code. Press〖+〗or〖-〗to set the value. Press〖SET〗to return to parameter code selection.
Keep〖SET〗depressed for 3 seconds to exit, and save the settings.
The status will exit, and the settings will be saved, if no key operation for 10 seconds.

Control
Cooling Control (P0 = C)
If Troom ≥ Set-point, the relay energized;
If Troom ≤ Set-point – P1, the relay de-energized.
Heating Control (P0 = H)
If Troom ≤ Set-point, the relay energized;
If Troom ≥ Set-point + P1, the relay de-energized.
Relay Delay Protection: After power supplied, the relay could be energized after P5.
Restore to Factory Default Settings 
Keep〖+〗or〖-〗depressed simultaneously, then supply power.
One second later, all settings will be restored to factory default values.
Attention
For ac/dc module as load, the rated current should be no more 1/10th of output specification under pure resistance;
For tungsten lamp as load, the rated current should be no more 1/15th of output specification under pure resistance:
For motor, the rate current should be no more 1/5th of output specification under pure resistance.
For example: if drive a 1100W tungsten lamp with 5A (pure resistance spec.) relay, the relay contactor will be burnt immediately.
