BEFORE STARTING THE INSTALLATION OF THE ELECTRASTREAM CHECK ALL COMPONENTS HAVE
BEEN DELIVERED AND ARE IN SATISFACTORY CONDITION - Refer to 1-3 .
If the over temperature cut-out trips more than once, switch off the Electrastream
isolating switch and contact your installer.
2-1.4 Heating Motorised Valve
When the room thermostat is calling for heat and the Electrastream control unit is set for
heat ON, the heating motorised valve will open allowing water to the radiators.

2-1.5 Pump
ols ols ols ols
The heating circulating pump is controlled by the Electrastream Control Unit in response
to the room thermostat.
The pump has 3 speeds, it is normally set to speed 2 (II). Consult the Electrastream
installer before changing this setting - see 4-4.3.
Display icon ‘'Pump
2-1.6 Room Thermostat
The room thermostat controls the heat within the property.
When the room thermostat is calling for heat and the Electrastream control unit is set for
heat ON, the heating circulating pump will run, pumping water through the radiators.

2-1.7 Tri-core Heater Elements
The three elements heat the water in the cylinder when the Electrastream control unit is
programmed for a heat cycle. The elements are switched On and Off by the
Electrastream control unit in response to the temperature within the cylinder as detected
by the temperature sensor.
The elements have a staggered On sequence to prevent sudden loads - see 1-5.
Display icons ‘'Heat 1
heating.
If either of the Heat icons are displaying an exclamation mark ‘'!’' ‘'!’' ‘'!’' ‘'!’' ‘'!’' this indicates a fault with
an element - see 2-2.3.
2-1.8 Residual Current Device (RCD)
The Electrastream system will be protected by a Residual Current Device, this will
automatically switch Off the electric supply if an earth fault develops.
The RCD must be tested at least every three months, this is done by pressing the RCD
‘'Test’' or ‘'T’' button, this should switch the supply Off. Reset RCD to On after test.
If the RCD appears not to be working correctly contact your installer or a qualified
electrician.
2-1.9 Alternative Heat Source Controls
For twin coil systems the alternative heat source will have its own controls - refer to
manufacturers instructions.
The alternative heat source would normally be a cost effective method of heating the
cylinder and should be used and controlled for optimum performance thus reducing
IMPORTANT
heating costs.
