Chapter 5. DETAILED DESCRIPTION OF EACH FUNCTION
• When [C26: Heat/Cool control] is set to [1: Enabled], the display and setting can
be made.
• When MV
≥
50%, the control is changed to the PID (heat).
• When MV < 50%, the control is changed to the PID (cool).
• When [C27: Heat/Cool] is set to [1: Energy saving], the heat/cool change is
suppressed to indirectly obtain the energy saving effect. However, when [C28:
Heat/Cool control dead zone] is less than 0.0%, the energy saving effect cannot
be obtained.
• How the relationship between the output (heat) and output (cool) is made for the
PID control result (MV) is set.
