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 higher than the block temperature this indicator
will light. If the light is on continuously the heater 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. If the block
temperature is above the set temperature then the indicator will be off, as the
heater is not getting any power.
