The DOWN ARROW Button
When the SET temperature button is
held down and the DOWN ARROW
button is pressed, the set temperature
is decreased.
Speed of Change of Set Temperature
Each press of the UP ARROW or DOWN
ARROW
buttons
will
increase
or
decrease the set temperature by 0.1°C.
If the buttons are held down the
temperature change will accelerate to
5° per second.
Power Indicator
The top indicator shows that there is
power to the unit
Power to the Block Indicator
The next indicator shows when there is
power to the block.
When the set temperature is different to
the block temperature this indicator
will light. If the light is on continuously
the block is getting constant power.
The only exception is described under
Over-Temperature
Indicator.
As
the
temperature
approaches
the
set
temperature the indicator will flash.
When set temperature is reached the
indicator will stay on for shorter periods.
Sensor fault Indicator
If there should, for any reason, be a
sensor fault, the bottom indicator will
light. The power to the block will have
been switched off and the unit will
begin to return to ambient even if the
power light is on (the light staying on or
not depends on which circuit has sensed
a fault).
