Delta Temperature Controller User Manual Display PV SV Explanations Status of the temperature controller Message displayed when DTA has not yet been connected to a sensor. Press for more than 3 seconds to enter initial setting mode Select the sensor connected. Default = PT100 Temperature unit. Default = °C Upper limit of temperature range Lower limit of temperature range The control modes include: PID, ON/OFF, MANUAL. Default = PID. Select “ON/OFF” here. Select heating or cooling mode.
Delta Temperature Controller User Manual Parameters relevant to ON/OFF control in the main screen of DTA to enter the “regulation mode”. Press Display PV SV Explanations Status of the temperature controller Set up hysteresis. Default = heating hysteresis. Can be set as cooling hysteresis as well. Both default values are “0”. or 2.2 MANUAL Press for 3 seconds in the main screen to enter the “initial setting mode”. Press times until the parameter Display PV SV Back to top several is displayed.

Press top to return to the main screen. Parameters relevant to PID control Press in the main screen of DTA to enter the “regulation mode”.
Delta Temperature Controller User Manual CHAPTER 3: CONTROL MODES IN DTB 3.1 ON/OFF There are four control modes in DTB: ON/OFF, MANUAL, PID and PID PROG. To switch to for 3 seconds to enter the “initial setting” mode. See below for how ON/OFF mode, first press to switch between each mode: Display PV SV Explanations Status of the temperature controller Message displayed when DTB has not yet been connected to a sensor.
Delta Temperature Controller User Manual Display PV SV Explanations Status of the temperature controller Set up Alarm mode 2. Default = alarm output disabled. Set up Alarm mode 3. Default = alarm output disabled. Set up system alarm ON/OFF of communication write-in.
Delta Temperature Controller User Manual Display PV SV Back to Explanations Status of the temperature controller The control modes include: ON/OFF, MANUAL, PID and PID PROG. Default = PID. Select “MANUAL” here. Press top to return to the main screen. Parameters relevant to MANUAL control in the main screen of DTB to enter the “regulation mode”. Press Display PV SV Set up heating or cooling control cycle. Default = heating, 20 seconds per cycle.
Delta Temperature Controller User Manual Display PV SV Explanations Status of the temperature controller ON/OFF of auto-tuning The 0th PID parameter. There are 4 groups of PID parameters built in DTB. When the parameter is set ass PID4, the system will automatically adopt the PID value of the current temperature closest to PID0 ~ 3.
Delta Temperature Controller User Manual 3.4 PID PROG Press for 3 seconds in the main screen to enter the “initial setting mode”. Press times until the parameter Display PV SV several is displayed. Explanations Status of the temperature controller The control modes include: ON/OFF, MANUAL, PID and PID PROG. Default = PID. Select “PID PROG” here. DTB offers 8 patterns and 8 steps for each pattern, totaling 64 steps. Range of a pattern: OFF ~ 7. OFF = the function disabled.
Delta Temperature Controller User Manual Display PV Explanations Status of the temperature controller SV ＋ Remaining time in the current step ＋ Target temperature for the current execution ＋ The pattern currently executed Parameters relevant to PID PROG control Press in the main screen of DTB to enter the “regulation mode”. Display PV SV Explanations Status of the temperature controller The 0th PID parameter. There are 4 groups of PID parameters built in DTB.
Delta Temperature Controller User Manual Display PV SV Explanations Status of the temperature controller Set up the position of decimal point Key-locked function Output volume. In PID PROG control mode, this is a read-only parameter and cannot be modified. CHAPTER 4: CONTROL MODES IN DTC 4.1 ON/OFF There are four control modes in DTC: ON/OFF, MANUAL, PID and PID PROG. Due to that DTC has no display panel, the settings and monitoring of parameters have to rely on communication.
Delta Temperature Controller User Manual Set up hysteresis. Default = heating hysteresis. Can be set as cooling hysteresis as well. Both default values are “0”. 2007-09-17 - 22 - © DELTA ELECTRONICS, INC.
Delta Temperature Controller User Manual 4.2 MANUAL Switch the control mode to MANUAL mode. Set up heating or cooling control cycle. Default = heating, 20 seconds per cycle. Manually adjust the output percentage. Assume the percentage value = 50 and the cycle = 20 seconds plus heating control, the system will conduct heating output for 10 seconds and stop for the other 10 seconds. © DELTA ELECTRONICS, INC.
Delta Temperature Controller User Manual 4.3 PID Switch the control mode to PID mode You can conduct auto-tuning on the default PID parameters according to the environment where your equipment is in or its temperature control capability, allowing the temperature controller to generate relevant PID parameters by itself in order to achieve an accurate temperature control. 2007-09-17 - 24 - © DELTA ELECTRONICS, INC.
Delta Temperature Controller User Manual 4.4 PID PROG Switch the control mode to PID PROG mode The 64 steps come from the combination of 8 patterns and 8 steps for each pattern. You can establish maximum 64 steps according to different systems in use. There are 8 steps in each pattern. You can define the step, loop and link pattern in each pattern. © DELTA ELECTRONICS, INC.
