OPERATING YOUR ST9400C
Choosing the Operating Mode (for Heating and/or Hot Water)
The operating mode may only be changed when the slider is set
to the RUN position.
A green INDICATOR LAMP shows when the heating or hot
water is switched ON.
Two MODE buttons are provided to select the Operating Mode
and therefore how the heating and hot water are controlled.
Heating has four possible Operating Modes; these are OFF, AUTO, ONCE, CONT.
Pressing the heating MODE button scrolls round these modes in sequence, and the
display indicates which mode is currently active.
•
OFF mode
The heating will remain
OFF.
•
AUTO (Automatic) mode
The heating will be switched
ON and OFF according to the heating programme.
•
ONCE mode
The heating will come
ON at the first programmed ON time, and go OFF at the
last programmed OFF time.
•
CONT (Continuous) mode
The heating will remain
ON continuously.
The hot water MODE button operates in the same way as described above for the
heating MODE button.
Overriding the Operation Without Changing the Programmes
In AUTO and ONCE operating modes, the OVERRIDE buttons switch the heating or
hot water ON or OFF without altering the programme.
When the indicator lamp is ON, pressing the OVERRIDE button switches the heating
or hot water OFF until the next programmed ON time.
When the indicator lamp is OFF, pressing the OVERRIDE button switches the
heating or hot water ON until the next programmed OFF time.
The LoT™ Display will provide you with information about the override.
