Description: SetOption73 Decouples the buttons and relay The VAR1 can be thought of as “NextSpeed” and VAR2 as “Next Power”, if it makes it easier to read the code

Notes:

• Relay 1 is the main light relay controlled by button1 (the light button)
• Relay 2 is the main fan relay controlled by the button2 (the fan button)
• Relay 3 is the secondary fan relay controlled by the bottom3 (the array buttons)
• Relay 4 is the tertiary fan relay not physically connected to any buttons

Rule Logic

• Relay 3 and 4 will always turn on with Relay 2
• VAR1 is set to 3 at Initialisation and when the fan is powered off to ensure full power to fan to startup
• VAR2 is set to 1 at Initialisation to control the fan “next power state”
• Button 2 will always toggle the power to the fan (and reset state)
• Button 3 will always decrease speed one at a time 3 -> 2 -> 1 -> 3
