INSTALLATION INSTRUCTIONS

They are fastened to the mounting surface through the two
diagonally opposed mounting holes in the back of the case.
See Fig. 1.
For access to the mounting holes, remove the cover from the
case by loosening the cover mounting screw.
The mounting holes are now visible through the circuit board
notches in the upper right and lower left-hand corners.
Determine placement of the mounting holes in the surface

R7500C WIDE RANGE PROPORTIONAL TEMPERATURE CONTROLLER COMPENSATION RATIO ADJUSTMENT CHECKOUT AND TESTING Compensation ratio is the number of degrees temperature CHECKOUT change required at the compensation sensor to change the primary sensor control point one degree F. The only checkout ordinarily required is to slowly rotate the When a compensation sensor (T2) is used, the compensation Setpoint Adjustment through the total proportional band of the ratio adjustment provides a means for

R7500C WIDE RANGE PROPORTIONAL TEMPERATURE CONTROLLER NOTE: 1. To ensure correct voltage readings in the following tests, a 500-ohm resistor should be substituted for the compensation sensor (if its temperature is not near 75F [24C]) and “comp. ratio” should be set at 20. 2. If the controller output is not connected, wire a 390 ohm “load” resistor from orange to yellow wires. R7500 Adjust setpoint knob to correspond to the ambient temperature at the main sensor. Set the proportion
