humidity reaches a set limit (default: 80%RH), sensor warming operation
is activated automatically. Sensor warming continues as long as the

When the warming starts, the sensor operation indicator is displayed on
the optional display and relays configured as "online status" (if any) will
be released. Warming does not affect T
