INTRODUCING YOUR SOLASTAT™ CONTROLLER
About Your
SolaStat™
Controller
Your SolaStat™ Controller has a microcomputer, which intelligently and
automatically controls water flow and energy inputs into your hot water
system.
Your SolaStat™ will balance water flow and energy inputs from solar, and
electrical sources so you can minimise your energy costs.
It has two main aims:
To make sure your hot water is being heated cost-efficiently.
To make sure you don’t run out of hot water when you need it.
How Does It
Work?
Your SolaStat™ Controller works by measuring and comparing the
temperature at three different places in the system: the collector (ROOF), the
top of your hot water cylinder (TANK) and the bottom of your hot water
cylinder (INLET).
If the temperature at the ROOF is higher than the INLET temperature by a
pre-set amount, then the pump turns on automatically to transfer heated
water from your solar collector to your hot water cylinder, and replace it with
cooler water from the bottom of the cylinder.
This makes the hot water cylinder heat up and the collector on your roof cool
down. When the temperature difference reduces to the pre-set level again,
the pump automatically stops.
It can also optimise the timing of heating your water, so heat is only applied
to the water in your cylinder when necessary, not all the time.
The SolaStat™ is also designed to protect your hot water system from very
high or freezing temperatures, as well as make sure that safe water
conditions are maintained (BioSafe).

THE DISPLAY PANEL
The
ROOF,
TANK
and
INLET lights indicate
which temperature is
being displayed.
If any of these lights
flashes, the unit is in
Smart Shutdown Mode
and ‘SSd’ will be
displayed.
NEXT Button
Press to obtain the next
displayed temperature.
The DISPLAY PANEL
shows
the temperatures of the
relevant sensors in 0C or 0F.
This is factory pre-set and
cannot be changed.
HWC Button
Press and let go for a one-off user heat up to
a maximum temperature – it will then switch
off and revert to automatic. Press again to
cancel.
When in Programming Mode, use this to
decrease the display value on the screen.
TEST Button
Press to test the display of the screen. ‘888’ will be
displayed and all the lights will be on at the same
time for about two seconds.
All the lights (except the PWR light) will then flash
and the display will show the number of times the
pump has been on (up to 999).
The
PUMP
light comes on when the
pump is on (in normal or FROST
operation, or when the PUMP button is
pressed).
The PUMP light flashes when the
maximum tank temperature has been
reached.
HWC
The HWC light is
on when the
element is on.
The TOPOUT
light is on when
the hot water tank
has reached its
maximum
temperature.
The
FROST
(and PUMP
)
light is on when the pump is
circulating water to stop the
collector from freezing.
CAUTION: Do not turn the
power off when the FROST
light is on.
PUMP
Button
Press and hold this button
to turn the pump on or off
(after it has run for ten
minutes, it automatically
switches off for one
minute, to let air escape
and prevent overheating)
When in Programming
Mode, use this to
increase the display value
on the screen.
