CAUTION
The exhaust duct will become hot during operation.
Danger of burning.
∅ Do NOT touch the exhaust duct during operation.
6. Start up
6.1 Switching on the unit
1. Insert plug into socket (chap. 5.1).
2. Switch on ED units of sizes 400 and 720 at the main switch (10)
The green “Standby“ LED illuminates
3. Press until the display lights up.
The controller is now in normal display (actual value display).
If the oven is operating (time functions “Continuous operation”, or “Timer
operation” with the set time just running down chap. 7.3), the actual
temperature value (example: 22°C) is displayed
If the oven is in time function “Timer operation” with no time programmed or the set time run-off (chap.
7.3), the unit is inactive (no heating). The display alternately shows the actual temperature value
(example: 22°C) and “tOff”:
6.2 Heating operation display
The heating and fan (with FD) are active as soon as the red heating
control light in the bottom right corner of the display slowly begins to
flash depending on the heat requirement (example: 70°C).
6.3 Air change
Opening the air flap in the outgoing air pipe serves to
adjust the air change.
Without connecting a suction plant:
• For BD and ED units fresh air circulation can be
elevated using the outgoing air pipe. The air flap in the
outgoing air pipe serves to adjust the fresh air entry.
• For FD units with the air flap open and the fan
operating, fresh air comes in via aeration gaps.
• If the air flap is completely open, the spatial temperature
accuracy can be negatively influenced.
