/**
* PID Chamber Heating
*
* If this option is enabled set PID constants below.
* If this option is disabled, bang-bang will be used and CHAMBER_LIMIT_SWITCHING will enable
* hysteresis.
*
* The PID frequency will be the same as the extruder PWM.
* If PID_dT is the default, and correct for the hardware/configuration, that means 7.689Hz,
* which is fine for driving a square wave into a resistive load and does not significantly
* impact FET heating. This also works fine on a Fotek SSR-10DA Solid State Relay into a 200W
* heater. If your configuration is significantly different than this and you don't understand
* the issues involved, don't use chamber PID until someone else verifies that your hardware works.

/**
* Max Chamber Power
* Applies to all forms of chamber control (PID, bang-bang, and bang-bang with hysteresis).
* When set to any value below 255, enables a form of PWM to the chamber heater that acts like a divider
* so don't use it unless you are OK with PWM on your heater. (See the comment on enabling PIDTEMPCHAMBER)
