Operating the Timer (224-PCMTX8 Only)
The timer function features three settings used to achieve the various modes of operation:
1. DELAYED START - The time period in minutes that will elapse prior to the pump starting to run. Setting
this value to zero disables the delayed start function.
2. SAMPLE PERIOD - The time period over which sampling will occur. Works in conjunction with the PUMP
PERIOD. Setting this value to zero will disable the timed run function and the pump will run continuously
until stopped using the START/HOLD key.
3. PUMP PERIOD - The time period in minutes during which the pump is actually running. If the PUMP
PERIOD is set the same or to a higher value than the SAMPLE PERIOD, the pump will run continuously
for the duration of the SAMPLE PERIOD. If the PUMP PERIOD is set to a lower value than the SAMPLE
PERIOD then the pump will automatically calculate on and off periods to apportion the required PUMP
PERIOD time over whole of the SAMPLE PERIOD time.
Setting a Simple Timed Run
Example: 8 hour timed run with no delayed start.
