Set DHW System Switch

Change the system switch of the hot water system. "Off" will set the system to "Always Off" and it will not follow schedule. "Heat" will set the system to "Always On" and it will not follow schedule.

To resume schedule after turning on the system switch, send a "off" command to /state.

Example Off:

{
    "systemSwitch": "Off"
}

Example On:

{
    "systemSwitch": "Heat"
}
