Configuration 4: Booster/Retrofit System
Notes:
Solar booster pump locked to run with filter pump - requires specific controller Dontek V7RTS. Solar pump
(13) should of lower flow than filter pump (4). A and B are the recommended temperature sensor installation zones
for the controller
Advantages:
Disadvantages:
* Less extra plumbing is required for solar
* Requires second pump and special controller
* Only filtered water runs through collectors
* Does not require separate solar suction provisions
* Large main filter pump + solar pump need to run all
day for solar
This configuration is not recommended for single story installs for pools with only a single
return port due to the potential over pressurization of the panels when both pumps run at
the same time. However for two story or greater installs, even with a single return port, this
is the recommended configuration for pools that don’t have separate su
ction ports.
