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 ).
