The heating and hot water system is all electric. The hot water for the taps (outlets) and
radiators is heated by the tri-core heater in the cylinder.
The system will have the following controls.

MIXING VALVE
UNVENTED CYLINDER
TRI-CORE HEATER
Fig. 2-1a Schematic of Typical Controls
2-1.1 Isolating Switch
The system will have a double pole isolating switch with neon and mechanical indicators.
This could be a pull cord or wall mounted type.
When the switch is ON (neon on) the system is operational.
When the switch is OFF (neon off) no hot water or heating will be available.
It is advised to turn the switch off when hot water and heating are not required, i.e.
holidays etc.
2-1.2 Electrastream Tri-core Heater
WARNING Unlike immersion heaters, the Electrastream tri-core heater
does not have an internal thermostat, therefore the cover should not need
to be removed.
When the cover is removed live electrical terminals are exposed.
ISOLATE THE TRI-CORE HEATER BEFORE REMOVING ITS COVER.
2-1.3 Over Temperature Cut-Out Thermostat
In the Electrastream temperature sensor box on the cylinder is the over temperature cut-

The over temperature cut-out thermostat is a manual reset type, this means it has a small

button that pops up when the thermostat has been tripped by overheating.
To reset the system after overheating, switch heating and hot water OFF, allow time for
the water to cool, or run off some hot water, then remove the cap and press the button.
