Features
– Temperature measurement range:-40.0~125.0 degrees Celsius
– Upper and lower limit temperature values can be set:0~125 degrees Celsius
– Measurement accuracy is 0.1 degrees Celsius, press K3 in standby mode to turn off display for a long time, reduce power consumption
– The relay output is a passive contact, no power output, can control the line on and off within 5A
– The delay time can be set to prevent the output from oscillating and causing damage to the entire circuit. For example, if the temperature is higher than 30 °C, the relay is disconnected. After the delay is added, the relay will not be disconnected immediately. If the temperature is lower than 30 degrees Celsius again during the delay period, the relay will not operate. Only the temperature is higher than 30 degrees Celsius. Set the delay time to disconnect
Wiring Port Description
DC-:power supply negative input
DC+:positive input of power supply
NC:Relay normally closed
NO:Relay normally open
COM:relay common
Description of the Function
P-1:Cooling control:When the measured real-time temperature is lower than T1, the relay is closed, and the relay is disconnected above T2;
P-2:Heating control:When the measured real-time temperature is higher than T2, the relay is closed, and the relay is disconnected below T1;
P-3:Constant temperature control:When the measured real-time temperature is between T1 and T2, the relay is closed, and the relay is disconnected in other cases;
P-4:Constant temperature control:When the measured real-time temperature is between T1 and T2, the relay is disconnected, and the relay is closed in other cases;
P-5:Single point control and delay time setting:The measured real-time temperature is lower than T, the relay is closed, higher than T, and the relay is disconnected.
Button Setting Instructions
K1:Press and hold for 2 seconds to enter the function setting or exit the function setting; short press to enter the upper and lower limit setting or delay time setting
In P-1 to P-4 mode:press K1 digital tube to flash, K2, K3 set the first set of threshold temperature T1, then press K1 digital tube to flash, K2, K3 set the second set of threshold temperature T2; in P-5 In mode:press K1 digital tube to flash, K2, K3 set threshold temperature T1, then press K1 digital tube to flash, K2, K3 set delay time
K2:button plus
K3:button minus
