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.

 Set deadband to 0 when a deadband or an overlap band is not used.
 If input display value is a decimal it is displayed as –999.9 to
999.9
 When proportional bands are different, the smaller one takes
precedence.
 Input sensor type (input.H, input.L) determines the use of a
decimal point.
