Tempco TEC-2400 - Control Output; Heat Only ON-OFF Control

Page 24 of 44
Formula: PV = INLO + (INHI-INLO) ((S – SL)/ (SH-SL))
Example: A 4 -20mA current loop pressure transducer with range of 0-15 kg/cm is connected to the input.
The following parameters should be set as follows:
INPT = 4–20, INLO = 0.00, INHI = 15.00, DP = 2-DP
The user may select a different value for DP to alter the resolution.

3.3.1 Heat Only ON-OFF Control
Select REVR for OUT1, Set PB to 0. O1HY is used to adjust the dead band for ON-OFF
control. The output 1 hysteresis (O1HY) setting becomes available when PB = 0. The heat only ON-OFF
control function is shown on the following page.
