D01-D06 Settings per step
Function:
Settings for step 1 to 6 of the Multiple Temperature Setpoints program.
Value:
D01 - D06: Step number 1 - 6:
Hours: Defines how many hours the temperature setpoint is used (from 1 to 999 hours). When
setpoint from "Set" is in-range, the time starts. Setting hours to Off clears all settings in
this step and the succeeding steps.
Set: The setpoint temperature to use for this step. Temperature change per hour (ramp) is
fixed for cooling, and change is done with maximum cooling capacity available.
%RH: Dehumidification - humidity setpoint. Values: Off, 50% – 95%. Off means the controller
maintains as high humidity as possible, at all other values the controller will use the hu-
midity setpoint to maintain dehumidification. Dehumidification is active immediately when
the step starts including under temperature ramps.
If the duration (hours) is set to OFF or it is the last step, the program is terminated. After this the
unit continues with the temperature set as last step in the MTS.
The Multiple Temperature Setpoints program stops automatically if the unit has been powered off
for more than 48 hours, or if the user stops the program or if PTI or Automatic Cold Treatment is
initiated.
