SETTING ECO MODE (703 SERIES)

Timer Functions for 703 Series Eco mode
The 703 Series Boiling Water Units are supplied with an energy saving Eco mode.
Eco mode is a 'Sleep Delay Mode' which when
activated will automatically shut the system down
after a set period of time with no use (2 hours).
To activate Eco mode, press and release the 'ECO' button. When the 'ECO' button is
released the green 'ECO' LED will illuminate to indicate the unit is in sleep delay
mode. Power will still be on to maintain set temperature until 2 hours with no use has
lapsed. After 2 hours with no use (from last inlet solenoid valve operation) the unit will
go to sleep at which time 'Treq' (Treq - temperature required) becomes 0°C (normally
97°C). When the unit is in sleep mode the red 'ECO' LED from 'PRESS ECO TO
HEAT' text will illuminate.
To 'wake up' the unit during 'Sleep Delay Mode', press and release the 'ECO' button
whilst the red 'ECO' LED from 'PRESS ECO TO HEAT' is illuminated. When the
'ECO' button is released the red and green 'ECO' LED lights will be extinguished,
sleep mode will be deactivated and operation will return to normal, heating the water
to the calibrated value, approximately 97°C.
To deactivate Eco mode, press the 'ECO' button whilst the green 'ECO' LED light is
illuminated. When the 'ECO' button is released, the green 'ECO' LED will be
extinguished and Eco mode is deactivated.
Note: Heating will continue as normal whilst in sleep delay mode until the 2 hour
period of no use time elapses. The 'ECO' button does not need to be pushed
for heating unless the red 'ECO' LED from 'PRESS ECO TO HEAT' text is
illuminated.
