aci TR-A-CP Series Installation And Operation Instruction

◼ Operating Specifications
The TR-A-CP-xxx Series room temperature sensors come with an output signal of 10K Ohms Type II (CP) at 77F (25C).
The temperature sensors have an overall accuracy of  0.36F
TR-A-CP-xxx Series room temperature sensors can be used in environments where the operating temperature is between
o o
40 to 122 F (4.4 to 50 C). Some part numbers include an adjustable resistive set point (1K to 11K ohms) and / or a
momentary N/O override "After Hours" pushbutton.
All part numbers with the "After Hours" Override pushbuttons
