A cycle time selected between 1 to 199 seconds indicates the total On/Off time
of each proportional cycle. For example, a 15 second cycle time means that
every 15 seconds the output will turn on for part or all of the cycle. For Relays’
Control Outputs, do not select a cycle time of less than 7 seconds or the relays’
lifetime will be shortened. For a cycle time of less than 7 seconds select SSR or
DC pulse. Use an external SSR with the DC pulse option for higher current
(higher than 1 Amp).
The DEADBAND Submenu will only appear if the ON/OFF was
selected from the "Control Type" Submenu.

(if Input Type is Process) around the Setpoint which the Process Variable
must pass above or below the Setpoint, before the output changes state.
