Yamatake SDC35, User Manual

Page: 80 / 280

• When the control method is other than the ON/OFF control (CtrL
≠
0), the
display and setting can be configured.
• [... for cool side] related items can be displayed and set when [C26: Heat/Cool
control] is set to [1: Enabled].
• When the Integral time (I-x) is set at “0s” or Integral time for cool side (I-x.C) is
set at “0s” in the Heat/Cool control, no integration control action is performed.
The Manual reset (rE-x) can be used in both the heat and cool controls.
• Parameter settings for the cool control are displayed only when the Heat/Cool
control is set enabled.
• When the Integral time for heat side or cool side is "0s", the operation is
processed with both Integral time for heat side and cool side set at "0s".
• If the setting is made so that the output low limit is greater than the output high
limit, the operation is performed with the low limit swapped for the high limit
automatically.
