The Solar Module
The solar module provides protection
against both cold and hot temperature
extremes. The solar module includes
the Hotlogic controller, which continually
monitors temperature conditions.
Freeze Protection
When temperatures approach freezing,
the Hotlogic controller removes the
water from the collectors to prevent the
water freezing and causing damage.
The Hotlogic controller rells the
collectors when temperatures improve.
Hot Temperature Protection
The water in the collectors can reach
dangerously high temperatures, which
may cause steaming, expansion and
over-pressure problems. When the
tank approaches its thermal maximum
(maximum energy storage limit), the
Hotlogic controller removes the water
from the collectors when it is safe to do
so, then rells them when conditions
improve.
Installation of the Solar Module
• The solar module’s drain line must be
safely plumbed to waste to comply
with AS3500.4 and local plumbing
codes. This line must not be con-
nected to the the PTR drain line.
• The water heater should be installed
to allow easy access and removal of
the solar module cover.
• The pipe extensions to the valve are
designed to provide a compression
connection, so soldering should not
be necessary. If soldering is required,
the pipe extensions should be re-
moved from the body of the valve to
avoid damaging the valve.
• It is critical that the solar non return
valve is installed on the solar collec-
tor return pipe, where the pipe enters
the middle of the storage tank.
• The solar module system satises
Level 2 test for severe frost condi-
tions (AS/NZS 2712:2007).
