(1) Commands may appear as Polled for (queried), Burst string item, Set command, or Notification.
(2) n = number, X = uppercase letter.
(3) Setting Peak Hold cancels Average, and vice-versa.
(4) In current scale °C or °F
(5) see section 9.3.2 Burst Mode, Seite 45
(6) No effect if relay in alarm mode.
(7) Relay goes to abnormal, display and analog out continue to provide temperature.
(8) 0000 places unit in alarm mode. Non-zero setpoint value puts unit in setpoint mode. Setpoint is in current scale. °C or °F. Must be within unit’s
temperature range.
