43. The temperature sensor (with the black cable) is
designed to measure the temperature of the
underside of the panel.
44. With a screwdriver, loosen the cable tie around
the cable hose. Push the temperature sensor as
far as it will go up the cable hose, so that it is
touching the underside of the panel (this should
be 700mm, but ensure that contact is felt).
45. To secure the temperature sensor in this
position tighten up the cable tie with a
screwdriver.
46. The temperature sensor connected to the back
of the ST 4 / ST 6 panel is then connected to
the FLOWCON B unit. Another temperature
sensor (with grey cable) is also connected to
the FLOWCON B unit and is the “Low Sensor”
used to measure the temperature of the hot
water cylinder (not supplied). If “after-heating”
(e.g. boiler) is included, the third supplied
sensor is connected to measure temperature at
the top of the hot water cylinder. The
FLOWCON B unit has connections for an
optional forth sensor for heat quantity balancing.
47. If the system has more than one collector panel,
they are connected in parallel. If the solar loop
comprises DN16 pipe work, we supply a pack
for each additional panel in lieu of the standard
connection kit (i.e. one panel will need the
standard connection kit, and each additional
panel will require a connector pack for
additional panels. If the solar loop comprises
15mm or 22mm copper pipe work, use an
appropriate standard connection kit for each
panel, and appropriate copper fittings to form
the tees.
48. The solar panel system should now be filled,
connected to the electricity supply, tested and
commissioned (see “
HEALTH AND SAFETY,
AND GENERAL REQUIREMENTS”).
Please
refer to the pump station manufacturer’s fixing
instructions and manuals for full details.
The system must be filled only with a liquid
mix suitable for flat collectors.
It is important to set the pump to the flow
rate specified for the system.
The “FlowCon” pump stations (pump plus
controller) that we supply can be connected to
the electrical mains via the included three-pin
13-amp plug (with 5-amp fuse fitted) directly to
a mains socket. This does not require Building
Regulations Part P compliance. Alternatively,
the connection can be made via an isolating
switch to a 5-amp fuse on the fuse board. This
alternative must be in accordance with Part P of
the current Building Regulations (via a Building
Regulations application or use of an accredited
electrician).
