4 solar circuit safety thermostat
In order to meet the requirements for unvented hot water cylinder
systems (G3), you must connect the power supply for the solar
pump (3) via a manually resettable safety thermostat (TCO) in the
solar cylinder.
The Flurocyl
2
solar cylinder is fitted with an appropriate safety
thermostat (4) at the factory. If the cylinder temperature is higher
than 80 °C, the safety thermostat interrupts the power supply to
the solar pump.
8.2.1 Cylinder frost protection
If you want to put a cylinder out of operation where it may be
at risk from frost, you must drain it completely. It is drained at
the cold water inlet with a T-piece with tap to be provided by the
installer.
Any heat exchangers not filled with solar fluid in rooms which are
at risk of frost must also be completely drained.
