Fail Detect Time (Min)
Range : 0 to 250 Min.
Default : 10 Min
This parameter sets a timer. If either temperature or %RH process value exceeds “High Alarm Deviation” limit, the timer starts
counting down. If the process value does not return below the “High Alarm Deviation” limit before the timer reaches 0, the
working control gadget set is detected as failed. The controller then switches to the alternate control gadget set.
Cyclic Time (Hrs.)
Range : 0 to 500 Hrs.
Default : 48 Hrs.
If both, Main & Standby, control gadget sets are in working condition, the controller keeps switching between these two sets
periodically with a time interval set by this parameter value.
Inhibit Time (Hrs.)
Range : 0 to 250 Hrs.
Default : 1 Hrs.
This parameter sets a time interval for which the controller stops monitoring the control gadget fail detection condition
(described under parameter “Fail Detect Time”). This time interval is usually applied under following conditions.
1. System is powered (Start Up)
2. Change-over from Auxiliary Power source (Battery / Inverter) to Mains Power
3. After recovery from Door Open Alarm
4. Change-over from Main to Standby Control gadget Set or vice-a-versa
This feature suppresses false detection of control gadget failure.
