If a mechanical relay or contactor is switching power to the load, a longer
cycle time may be desirable to minimize wear on the mechanical compo-
nents. Typical life of a mechanical relay is 100,000 cycles.
Range: 0.1 to 999.9 seconds Default: 5.0 seconds
Alarm Low: Represents the low process alarm or low deviation alarm. This para-
meter will not appear if [`Ot2] is set to no or [`Con].
Range if [`Ot2] is set to [`dEA] or [``dE]: -999 to 0 Default: -999
Range if [`Ot2] is set to [`PrA] or [``Pr]: [``rL] to [`AHI] Default: [``rL]
Alarm High: Represents the high process alarm or high deviation alarm. This
parameter will not appear if [`Ot2] is set to [``no] or [`Con].
Range if [`Ot2] is set to [`dEA] or [``dE]: 0 to 999 Default: 999
Range if [`Ot2] is set to [`PrA] or [``Pr]: [`ALO] to [``rH] Default: [``rH]
Calibration Offset: Adds or subtracts degrees from the input signal.
Range: -100°C to 100°C/-180°F to 180°F/-180 units to 180 units; or
-10.0°C to 10.0°C/-18.0°F to 18.0°F Default: 0
Autotune: Initiates an autotune.
Range: 0 is set to off, 1 is set to slow, 2 is set to medium, 3 is set to fast
