INTRODUCING 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 minimise your energy costs
It has two main aims –
B To make sure your hot water is being heated cost-efficiently
B To make sure you don’t run out of hot water when you need it
Your SolaStat™ Controller works by measuring and comparing the
temperature at three different places in the system:
1. the collector (ROOF),
2. the top of hot water cylinder (TANK) and
SolaStat™-1-3 User Guide
3. the bottom of your hot water cylinder (INLET).
If the temperature at the ROOF is higher than the TANK 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.

THE DISPLAY PANEL
SolaStat™-1-3 User Guide
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.
PUMP Button
Press and hold this
button to turn the
pump on. Repeat this
again to turn the pump
off.
After the pump 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.
The DISPLAY PANEL
shows the temperatures
of the relevant sensors in
0
C or 0F.
HWC Button
Normally used to activate a one-off heat up
of the Hot water cylinder element.
Note that this is not active in this model.
When in Programming Mode, use this
button to decrease the display value on the
screen.
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.
NEXT Button
Press to obtain the next
displayed temperature.
TEST Button
Press to test the display of the screen. ‘888’ will be
displayed and all the lights (except the PWR light)
will be on at the same time for about two seconds.
All the lights will then flash and the display will show
the number of times the pump has been on (up to
999).
HWC
The HWC light is
not active in this
model.
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.
Helping you
to achieve
Power
Savings
Your SolaStat™ helps you save power by controlling the amount of hot water
that enters your tank.
Your SolaStat™ is set to make the pump automatically turn on or turn off,
depending on the temperature in the tank and at the collector.
You can manually alter the amount of water entering your tank by using the
PUMP button.
