QA:
Q: Why there is no output voltage？
A: This is a relay temperature controller, There is no voltage output directly, you need to connect additional power supply for the load, then it can turn on/off the load.
Q: There is a way to calibrate when temperature gives error?
A: Yes, In normal working status, press SET for 3 seconds to enter into setting parameter mode. When display HC, press UP or DOWN button to switch codes to CA ( -30.0°F～30.0°F/-7℃~7℃ )
Q: Why it does not turn off the light as setting ?
A: Please check if you set the value for PL, if PL≠0, the display will flash, the cooler or heater only start to work after the time of PL.
Q: Why it only can be set in limited range, not as description -22~572℉/-30~300℃
A: HS and LS can set the high and low limit of setting temperature: For example: if HS = +60, LS = -10, the setting temperature only can be
set between -10~+60. so if you want to set a value beyond this range, please change HS and LS at first.
