Product function introduction: The one-way temperature controller can set as "refrigerating" or "heating", using 10K general NTC thermistor to control temperature, control the one-way relay (NO, NC) output. The temperature range controlled is -45-110. It is used extensively in various refrigerating and heating situations. Under refrigerating mode, the output opens when the temperature is above (temperature control value + backlash), and stops when temperature is the at temperature control value. Under heating mode, the output opens when the temperature is below (temperature control value - backlash), and stops when temperature is the at temperature control value. The temperature control value and backlash are adjustable. Correction function for temperature deviation is also available. DIN rail-type installation is adopted which is easy and fast for installing. The advanced design of isolating power supply is adopted, which can ensure the controller work steadily, reliably, and continuously when the power supply changes between 100V and 240VADC. Main Features: One-way 10K NTC temperature sensor input One-way NO & NC output Temperature display Shifting between the refrigerating and heating modes Delay protection of compressor Correction of measured temperature deviation Power-down memory protection function Panel introduction 1.The indicator light is lit when the relay NO pulls-in. 2. LED display window: temperature is displayed during work (T temperature = T temperature measured + T deviation) 3. (erected triangle)is parameter plus adjust key under set state; Under work state, press it for long to check the temperature control value set. 4. (SET) set key, press it to start the parameter set state and press one by one to shift to display each parameter. 5. (Inverted triangle)is parameter minus adjust key under set state. 6. If no action is conducted in 3 min after adjusting, the interface will return to the main interface automatically, displaying current temperature. Detailed introduction of the control function: Short name of control function Control function introduction Other introduction Temperature measuring correction Displayed T temperature = T measured temperature + T deviation Temperature control output 1. Under H mode, when T temperatureT temperature control, the relay NO is off, output stops; when T temperature is(T temperature - T backlash), the relay NO pulls-in again, heating output starts; 2. Under L mode, when the T temperatureT temperature control, the relay NO is off, output stops; when T temperature is(T temperature + T backlash), the relay NO pulls-in again, refrigerating output starts; The time for relay output open-- close or close-- open shall not be shorter than the Pt set value. Operation guide: Press(SET)to start setting parameter, press one by one to shift to display each parameter; (erected triangle)(Inverted triangle )is used to adjust the value. After setting, press continuously the(SET) key until the main interface is get.
