setpoint temperature has been reached, even if the programmed heating
time has already elapsed.
SPWT (H)
SET-POINT WAIT (humidity)
Wait until set humidity is reached.
The unit starts with the next programme segment only when the
programmed humidity setpoint has been reached, even if the
programmed heating time has already elapsed.

SET-POINT WAIT (temperature
and humidity)
Wait until set temperature and set humidity are reached.
