R-Pac Option: Heating Priority - Polytropic PAC 16 Manuel D'instructions

R-PAC option: Heating priority

This option enables the heat pump to control the filtration of the pool if the set
water temperature has not been reached. .
The heat pump will re-start the water pump in order to extend the filtration
cycle time.
When this option is set, the heat pump will start the water filtration pump for 10
minutes, every 200 minutes to test the water temperature. If the temperature is
below the set temperature, the heat pump will start heating maintain the
filtration pump in working mode during the same period of time.
The heat pump has a contact normally open (4 A aprox), between terminals "9"
et "10" which controls the start up of the filtration pump.
In order to activate this option, you only have to connect terminals "9" et "10"
of the heat pump R-PAC In the following way:
• Either in parallel with normally open contact of the timer which controls the
water filtration pump.
or
• Directly on the relay that controls the start up of the water filtration pump as
follows:
R-PAC terminals
Warning: if the installation is three phased (R-PAC31T), the phase used in
terminals "9" and "10" must be the same phase as the one connected to
the power supply terminal'3' on the R-PAC31.
Connect relay power supply phase to terminal "9" of R-PAC (Wire A)
Connect relay control phase (terminal A1) to terminal "10" of R-PAC
