CYCLE/PULSE TIMER
The cycle/pulse timer will cycle the pump on and off based on the time settings in the timer, TH represents on time
and TL represents the off time.

1. The following feature is available in “Set Param” and is labeled as “CYCLE T” the default setting is 1
minute on and 1 minute off but is disabled.
2. To access, enable and set cycle/pulse times, follow the steps in 9.2 "Setting Auxiliary Parameters”
3. To enable the cycle timer feature the “CYCLE” “Switch=off” needs to be set to “Switch=on.

5. The cycle/pulse feature will cycle/pulse the pump module while operating in “Auto”
CAUTION-do not set the off cycle time shorter than 1 minute in order to avoid motor overheating.
DISABLING F1 “MANUAL RUN”
If the system includes zone controllers or zone valves, and is run in Auto, F1 should be disabled. By
disabling F1, the pump system has to be started and stopped by a remote input from a zone controller, or
another control device, and the pump would be in “Auto Ready” (press F2).
WARNING, operating the pump unit in F1 “Manual Run” with zone controllers or zone valves installed in the system,
could cause the pump to dead-head resulting in damage to the pump unit that would not be covered under
warranty.
1. F1 disable is located in “Set Param” and is labeled as “F1 DISAB” the default setting is off. The soft key
settings represent:
a. Off = F1 is enabled
b. On = F1 is disabled
2. To access, enable and set F1 operation, follow the steps in 9.2 “Setting Axillary Parameters”
