Do you have a multimeter or any way to run some tests on this thing?
Pretty sure this is the same item below. Poorly translated instructions; which seems to be what you say you've tried.

Operation method
Because there are two kinds of heating and cooling demand, so the thermostat we have "hot start" and "cold start" two kinds of mode of operation.
1.High temperature start"When the start temperature is greater than the" stop temperature "," high temperature thermostat in the start state. For example: a "stop" temperature is 20 ~ C, the start temperature is 30 DEG C, then when the measured temperature reaches 30 DEG C, open the machine, the operation indicator light (green) light, the power supply socket. When the measured temperature dropped to 20 degrees C, shut down the machine, the standby indicator light (red light), the power socket. This starting method is mainly used for cooling, such as open air conditioning exhaust fan, etc..
ThreeLow temperature start"When the start temperature is less than the" stop temperature ", the thermostat in" cold start ". For example: a "stop" temperature is 30 ~ C, the start temperature is 20 DEG C, then when the measured temperature reaches 20 DEG C, open the machine, the operation indicator light (green) light, the power supply socket. When the measured temperature rises to 30 degrees C, shut down the machine, the standby indicator light (red light), the power socket. This starting method is mainly used for heating.
Set the memory function: the thermostat will set your storage time, ensure the power settings will not be lost, without additional settings.
and another site with it here has some additional info in the instructions (again poor translation); but it seems to imply that there could be a heating mode (and then possibly a cooling mode) where the unit will cut power once the set temp is reached.

Makes me wonder if its looking for a ground and maybe you dont have a good ground?
pro : we have the car thermostat and we can timer combination clock thermostat , which the expansion of your thermostat phenylketonuric application range !

operation method
due to have heated and cooling two kinds of demand , therefore our thermostat also have & ldquo . start & high temperature rdquo . and & ldquo . low temperature starting & rdquo . two way .
1 . start high temperature : & ldquo . when the starting temperature & rdquo . greater than & ldquo . stop temperature & rdquo . when , thermostat in the & ldquo . start & high temperature rdquo . state . such as : set & ldquo . stop temperature & rdquo . for 20 & deg . c , & ldquo . start temperature & rdquo . for 30 & deg . c , the measred then when the temperature achieves 30 & deg . c when , machine to open the , operation indicator lamp ( green bright ) , of the indemnifiable socket supply power the measred when temperature 20 & deg . c when , machine closed , standby indicator lamp ( red light bright ) , of the indemnifiable socket cut this is mainly used for starting mode to cool , open air conditioning , paiqishan etc .
3 . low temperature starting : & ldquo . when the starting temperature & rdquo . less than & ldquo . stop temperature & rdquo . when , thermostat in the & ldquo . low temperature starting & rdquo . state . such as : set & ldquo . stop temperature & rdquo . for 30 & deg . c , & ldquo . start temperature & rdquo . for 20 & deg . c , the measred then when the temperature achieves 20 & deg . c when , machine to open the , operation indicator lamp ( green bright ) , of the indemnifiable socket supply power when to the measred 30 & deg . c when , machine closed , standby indicator lamp ( red light bright ) , of the indemnifiable socket cut this is mainly used for starting mode heated .
Memory function : settings thermostat 'll store your settings , ensure the power is not lost settings , dynamo charging instated .
warm tip : if you like this paragraph thermostat , but you need control equipment power greater than 800 tile , so your thermostat with a us power expansion module can control 3000 tile below heated : equipment
you also can use ac contactor to capitalise high power appliances . ac contactor with thermostat combination of the wiring can environmental : chart
about accuracy temperature :
many pro buy our thermostat after , like home or others thermometer to check our thermometer accuracy . due to the supermajority family thermometer take no periodically remedical metering , therefore , simply can not as standard econometrics utensils us to identify thermostat the accuracy !
other , some pro though we put the thermometer and temperature controller probe placed a insulation the box inside detection , but as the boxes 's itself won't uniform , led to look great difference between .
suggest to do do pro following test : put in your probe clip armpits for awhile , because of the adult normal temperature is 36 to 37 degrees , us thermostat largest error is the positive and negative 1 degrees , therefore , as long as our at this time temperature controller measuring temperature in 35 - 38 between , so 'll can think our thermostat temperature measurement is normal .
mattersneeding attention
1 . will be this instrument installed in dryeration counter

3 . can't thyself open this machine , with fault to dealers with this company connection
4 . book machine for do not have the boiler safety protection function , can't water-sprayed , noretry . close to the fires
5 . emplace please in child reach place !
special tips : when the products in the hot mode , often used & ldquo . electric heater & rdquo . heated , when heated reaching the set temperature , product immediately cut off & ldquo . electric heater & rdquo . power supply . but due & ldquo . electric heater & rdquo . power-off won't immediately after cooling , but continue to be hot issued , display products such temperature will continue , than setting in high temperature 1 - 2 degree only after decline , the normal phenomenon , client can through adjust temperature sensor position correct the .
When initially plugging them in the left number was higher than the right but I cannot recall exactly what the setting was. I assumed left was the high number, right was the low number and middle is the current temp. I've tried both ways though and cannot get power through the device to a heater.
