EcoVFC Proportional Alternating Circuit
Feature (Software Version 1.24)
To enable the Proportional Alternating Circuit feature on the
EcoVFC with software version 1.24 or higher:
Set SW3 position 8 to the ON Position.
Set SW6 position 4 to the ON position. This activates
the timed alternating circuit mode. This switch
needs to be enabled on the master EcoVFC only.
Set SW6 position 5 to the ON position. This switch
activates the proportioning feature and needs to be
enabled on the master EcoVFC only.
Set SW2 to the desired address for pump run time.
Each EcoVFC address will be set based on the
time it needs to run (Table 3).
Note
: This is different from the typical Master EcoVFC
address of “0” (See figure 6 for switch locations).
Example:
• For a Master controller with a 20,000 gallon tank,
when set to address 20 the pump will run for 30
minutes.
• For a Slave controller with a 12,000 gallon tank,
when set to address 12 the pump will run for 18
minutes.
• For another Slave controller in an 8,000 gallon
tank, when set to address 8 the pump will run for 12
minutes.
Any address can be set, as long as the addresses are
unique between controllers. Typically addresses and
run times will be chosen that are proportional to the tank
sizes. The example shows 3 different size tanks and the
addresses that run the pumps in proportion to the tank size.
