Problem with/wrong state in mix and electricity mode

[mabulaza]

Great work!
However I have a remark.
In select enum.h are the energy combinations defined:`

enum class TRUMA_SELECT_TYPE_HEATER_ENERGY_MIX {
GAS = 0,
MIX_1 = 1,
MIX_2 = 2,
ELECTRIC_1 = 3,
ELECTRIC_2 = 4,
`
In mix mode the "Energy mix" shows 3 or 4, in electrical mode only it shows 1 or 2. Should it be vise versa?
May be consequently in mix mode the sensor "Heater mode GAS" shows off, instead of on. This shows only "on" in GAS only mode.
