Temperature controller W3230 12V The regulator can perform the function of: Heating cooling in the range from -55C do 120C with the possibility of setting: Alarm (visual) Upper/Lower Temperature Limit Hysteresis Relay switching delays Temperature deviation settings The NTC10K temperature sensor is included! Technical data: Power supply: DC 12V Temperature measurement range: -55 - 120C Output load capacity: max. 20A/14VAC, 10A/250VAC Temperature sensor: waterproof NTC10K by debt. approx. 1m Sensor Diameter: 5mm Sensor sleeve length: 25mm Measurement accuracy: 0,5% or /- 3C Accuracy of indications: 0,1C (do 99,9C) and 1C (above 100C) Refresh Rate: 0.5 sec. Operating temperature: 0 to 50C Dual LED display: temp. Measured (PV) and set (SV) External dimension: 79x43x26mm -1mm Mounting dimension: 72x39 (depth 25mm) Programming: MENU - to enter the programming system, hold down the SET button for about 4-5 seconds. Select the programming mode P0 - P6 select with the buttons and - Entering the selected mode is approved by the SET button Approval of the selected value with the SET button Programming modes P0 - P6 P0 - choice of C/H cooling or heating P1 - range of hysteresis operation can be selected from 0.5 do 15C P2 - upper temperature limit (default 120*C) range -45C do 120C P3 - lower temperature limit (default -55*C) range -55C do 120C P4 - thermometer calibration in the range of -7C do 7C (set when temperature indications are wrong) P5 - delay time of switching on the relay in the range 0min do 10min P6 - alarm too high temperature can be set 0 do 110C (visual alarm) Switching on the buttons at the same time and - when the power supply voltage is switched on, it resets do factory settings
