Matters needing attention:
In order to avoid the danger of oversetting the temperature due to misoperationby others, the thermostat has the upper limit function, which limits the settingrange of the maximum temperature setting point controlled by the thermostat. Press +- to switch to P2. Press SET once to SET the upper limit. Press +- to SETthe temperature that can be SET by the peak value. For example, if it is set to60, the peak value of the temperature setting point can only be set to 60° C.To expand the range of the temperature setting point, you need to adjust theupper limit

P3 Setting Lower Limit for Low Temperature:

In order to avoid ice blockage caused by misoperation of others, the thermostathas the function of setting the lower limit, which limits the setting range ofthe setting point of the low limit temperature controlled by the thermostat. Long press SET5 seconds to display PO press +- to switch to 3 press SET once toset the lower limit, press + 1 to set the temperature that can be set at thepeak. The minimum value is -50. After the setting is complete, press SET once toreturn and hold down SET or 10 seconds without key action. The controllerautomatically confirms that the setting is complete. For example, Set thetemperature setting point to 2

P4 Temperature correction :
When the measured temperature is different from the standard temperature or theuser hardware has special needs, this function can be used for correction. Thetemperature after correction = the temperature before correction + the effectiverange of correction is-7.0~7.0(unit C).Long press SET for 5 seconds to display PO, press + everything to change to P4press SET once for correction, press +- to SET the correction value, press SETonce to return after completion, long press Set or 10 seconds without press thecontroller to automatically confirm completion.
