[ENHANCEMENT]: Utilize powerful mode instead of backup heater.

[MikeyMan83]

The Panasonic offers a powerful mode that, at least on the J-Series T-Cap, offers 10% extra power.
Now it is limited to four specific one-time setting:

TOP17 | main/Powerful_Mode_Time | Powerful state in minutes (0, 1, 2 or 3 x 30min) -- | -- | --

The current flow only seems to allow a one time setting, and gets blocked after that.

Request:

• Clean up current logic to enable setting it multiple times in a row.
• Be able to set this functionality with certain constraints (If temperature is <x then set powerful mode for x time)
• Be able to run this functionality for longer by consecutive execution of it. 5 hours = 10 times mode 1 in a row.

Stretch assignment: combine with backup heater in some way...?

Rationale: 10% extra power output is far more efficient than running the COP1 backup heater.

transmit OFF signal to indoor when the timer is complete. Indoor will transmit signal to outdoor for frequency control.
Indoor setting temperature shift
 If system is standard system (Optional PCB is not connected)
o Target water temperature will shift up to Wlo or Whi whichever higher.
 If system is extension system (Optional PCB is connected)
o Target water Zone 1 and Zone 2 temperature will shift up to Wlo or Whi whichever higher.

• If “Direct Type” temperature control is select, this powerful shift up setting is not effective.
   Start condition
  o Powerful function is select by remote control.
