Perimeter Heat
This application also supports the optional control of perimeter heat. The algorithm supports analog,
three-point floating, pulse width modulation, and on/off control of the perimeter heat. Perimeter heat
operates independently of terminal airflow.

In1 through In6 can be used for digital or analog inputs, as follows:
• In1 through In6 are dry contact inputs (with resistors)
• In1 and In2 also accept 10K ohm inputs
• In3, In4, In5, and In6 also accept current (4 to 20 mA) and voltage (0 to 10 volt) inputs
A1, A2, and A3 are 0 to 10 volt outputs only.
