intensity (optional), as quickly as possible and reach a relative humidity of 70 % rh. Once the
temperature and humidity have been reached, the constant climate chamber should retain
the setpoint values for 45 minutes at 80 % light intensity and then cool down within one

Settings example programming mode
Before programming ramp sequences, especially before programming complicated ones,
it is recommended that you prepare a similar plan to ensure that you enter the required
ramp commands correctly, as described below. For better orientation, it is recommended
that you programme large programmes graphically on the computer using the "Celsius"
software.
