The control box is pre wired for 240 volt power,
and directing power to the pump.
From the L H S. Power in with brown L (positive),
blue N (negative), and green/yellow as the earth.
Next is the power to the pump (same colour for L,
N, and the earth. T1 is the sensor to the collector
outlet. T2 is the sensor to the bottom of the tank,
and T3 is to the middle of the tank.
Please refer to the supplied manual for the control
box. This control box can be located away from the
tank area if desired. Alls that needs to be done is to
extend the length of the power to the pump, and T2
/ T3 sesor cables.
Please ensure that same colors are joined when
extending
. T1 still goes direct to the control box
from the collector.
This is the wiring sequence for the power from
the control box to the pump. L, N, and E.
Sunpower pre assembles the pump fittings
.
Below the pump we have a silver stop valve
(same as solar return). Above the pump we have a
high temperature check valve (same as solar
return). This isolates the pump, and also isolates
the collectors on the solar flow if required
.
Please ensure the power to the pump is
switched off, when isolating the collectors.
