Royal packs a dual boiler, one dedicated to steam and the other to brew water, both of which are regulated by individual PIDs. In combination with the traditional E61 group, which constantly syphons hot water through the brew circuit, this makes for seriously temperature stable operation.

The Fourth, Instructions of the control panel:
1. Each key purpose:
(1) "P" key
This key has two uses : The first use is to direct press "P" key to switch up or down needle position, if up pinhole lamp lights means up needle position, if down pinhole lamp lights means down needle position, if two lamps off means no needle position.
The second use is: Function Enter button, below point 2 are described below.
   "S" key
This button also has two uses : The first use is to simply press "S" key to off or on lamp on the head.
The second use is to function parameters ( confirm ) key, point 2 are described below .
"+" "-" key
 These two keys are used to adjust speed.
(2) To enter the parameter method of operation:
     Example: How to change the motor from clockwise to Counterclockwise
     The first step: Open the power;
     Step two: Press the "P" key, no leave, and use the other hand press the "+ " key , the screen will display the P-00
     The third step: press "+" key, the screen will display P-01, and then press the "+" key again, the screen will display P-02, (P-02) is a motor clockwise or Counterclockwise parameters (common parameter list has).
     Step Four: Now press "P" key (enter into parameter) screen will display "1"
     Fifth step:  press " - " key, change "1 "to "0"
( "1" clockwise " 0 " for the counter-clockwise , common parameters list has ) .
     Step Six: Press the "S" key to determine the parameters, save and exit the parameter.

     Restore factory settings : Press the "P" key, no leave, and use the other hand press the "+ " key , the screen will display the P-00, then press "S" key 3 seconds, it will Restore factory settings.
Insulated stainless steel boilers for brewing and steaming offer better temperature stability compared to heat exchanger and single boiler espresso machines. Brew back-to-back coffees or brew and steam at the same time.
PID Controller
The PID temperature controller helps with temperature stability, turning the boilers' heating elements on and off for moments at a time to keep temperatures exact. The LED screen on the front of the machine offers a readout of brew and steam boiler temperatures, freely adjusted by the adjacent buttons.
Direct Water Line Connection
With the included plumb kit, you can hook up your Royal directly to a water line, bypassing the water reservoir for an infinite supply of water. With the machine plumbed in, there's no need to refill the tank ever again.
Dual Manometer
The colorful dual manometer on the face of the Royal gives you a live reading of the brew and steam pressure while the machine is in operation. There's no easier way to keep an eye on performance.
