The power supply to the booster heating unit can be either a
continuous / time of use
or an
Extended Off-
Peak (overnight and day)
power supply and may be controlled by a
Timer Control Switch
. Discuss the power
supply requirements to the booster heating unit with the householder. The power supply to the solar controls
must be a continuous power supply.
Continuous Power Supply
A single active is required from the switchboard if the solar
storage tank is connected to a continuous power supply.
The active from the continuous circuit must be connected
to the active terminal marked A1 (marked “Controller” on
the wiring diagram) on the terminal block of the solar
storage tank.
A wire is supplied bridging the two active terminals marked
A1 and A2 (marked “Controller” and “Booster” respectively
on the wiring diagram) on the terminal block of the solar
storage tank. This is required if the water heater is
connected to a continuous power supply and a timer
control switch is not installed in the power supply circuit to
the booster heating unit.
Refer to the
continuous power supply wiring connection
diagram
on page 36.
A timer control switch can be installed in the power supply
circuit to the booster heating unit. Refer to
“Booster
Control”
on page 37.
Extended Off-Peak Power Supply
Two actives from two separate circuits are required from
the switchboard if the booster heating unit is connected to
an Extended Off-Peak power supply. A double pole
isolating switch is required to be installed at the
switchboard to simultaneously isolate both circuits.
The active from the continuous circuit must be connected
directly to the active terminal marked A1 (marked
“Controller” on the wiring diagram) on the terminal block of
the solar storage tank. This supply must remain
uninterrupted to allow the solar controls to operate and
solar gain to be achieved.
The active wire from the Extended Off-Peak Circuit must
be connected to the active terminal marked A2 (marked
“Booster” on the wiring diagram) on the terminal block of
the solar storage tank.
The wire bridging the two active terminals marked A1 and
A2 (marked “Controller” and “Booster” respectively on the
wiring diagram) on the terminal block is not required and
must be removed if the booster heating unit is connected
to an Extended Off-Peak power supply.
Refer to the
extended off-peak power supply wiring connection diagram
on page 36.
A timer control switch can be installed in the power supply circuit to the booster heating unit. Refer to
“Booster Control”
on page 37.
