Operation and Control
5.10.6 Close statements for ramp segments
Each ramp must be completed with a close statement connecting the ramp to the next one.
These commands thus control the programme sequence:
NEXT
Connect the next programme segment.
SET-POINT WAIT (T – temperature)
Wait until the setpoint temperature has been reached.
The appliance starts the next programme segment only when the
programmed set temperature has been reached, even if the set
heating up time has already elapsed.
SET-POINT WAIT (H – humidity)
Wait until setpoint humidity has been reached.
Appliance starts the next programme segment only when the
programmed setpoint humidity has been reached, even if the set
time has already elapsed.
SET-POINT WAIT (TH – temperature and humidity)
SET-POINT WAIT (TH – temperature and humidity SET-POINT WAIT (TH – temperature and humidity
Wait until setpoint temperature and setpoint humidity have been
reached. The appliance starts the next programme segment only
when the programmed setpoint temperature and programmed
setpoint humidity have been reached, even if the set time has
already elapsed.
Ramp repeat function
The programme entered is repeated after it has run through all
programmed segments.
1-99 = repetitions
loop = endless repeat function
Programme end while maintaining the temperature and humidity
of last programme ramp
Programme end, switching off the heating / cooling function and
humidification
