part using two latches. pull the side pieces
(cover plates) of the front of the housing out-
wards (Figure 16) to unlatch it and rotate up-
wards until the cover plate is opened.
6. Hang the Solar Controller onto two screws.
Screw in the two lower screws.
7. Tighten all screws so the unit is secure on the
wall.
!
nOTE: Do not over tighten to avoid damage to
the housing.
Wiring instructions
All low voltage wiring is located on the right hand
side of the Solar Controller and higher voltage wir-
ing is on the left hand side of the Solar Controller.
(Figure 17)
The lower voltage wiring in this system (S1 &
S2) consists of two temperature sensors: one
measuring the temperature of the solution leav-
ing the Solar Collectors (S1), and one measuring
the temperature of the water in the Solar Storage
Tank (S2). An additional temperature probe can be
installed in the top of the Solar Storage Tank (not
included) for monitoring purposes.
The temperature sensors are provided with 3 ft
(90 cm) of wire. Double insulated 20 ga two core
sensor cable can be used to extend the cable to
install the temperature probe to the solar collectors
or the Solar Storage tank.
!
nOTE: The Stainless Steel insulated corrugated
piping has sensor wire built in.
!
nOTE: Ensure that all wires to the Solar Con-
troller are installed with appropriate strain reliefs.
!
nOTE: The polarity of the sensor wire is not
important to the installation.
The Solar Controller is supplied with a plug that
is to be connected to
plugged into any 120V GFI protected receptacle.
The two pumps will be wired in parallel and will be
connected to A1 and n, with the wire that is pro-
vided. This will prevent any situations where one
pump is running without the other.
once the Solar Controller has been plugged into
the wall receptacle, verify that the connections for
