ON/OFF and PID control can be used for the heat and cool outputs in
several combinations.
The following lists the v alid control modes:
OP1 & OP2 VALID CONTROL MODES

Any other setting OP1-OFF OP2-OFF
TP - Time Proportioning
Note: In manual mode, the % output power is not limited to the output
power limits (OPLO & OPHI)
