temperature buttons
The setpoint temperature value can be set for each channel
separately by selecting three preset temperature values (fixed
temperatures).
Factory settings:
┌ 1 ┐ = 150 °C (300 °F),
┌ 1·2 ┐ = 350 °C (660 °F) ,
┌ 2 ┐ = 380 °C (720 °F)
1. Select a channel.
Three fixed temperatures are shown on the display for approx.
2 seconds.
A temperature value can be entered as long as the temperature
symbol (18) is flashing.
2. Set the setpoint temperature value with the UP or DOWN button.
3. Press the required temperature button ┌ 1·┐, ┌ 1·2 ┐ or ┌ 2 ┐
for 3 seconds.
The temperature display for the corresponding temperature value
flashes during this period.
