6.2.1.3.1. Deadband/Overlap Band

In heating and cooling control, it is possible to designate a deadband between heating
and cooling control bands based on SV (Setting Value).

A deadband forms around the SV when DB is set to a positive value. No control
occurs in the deadband area. Therefore, heating and cooling MVs become 0.0% in
the formed deadband.

An overlap band (simultaneous application of heating and cooling MVs) forms around
the SV when DB is set to a negative value.
