Measure
▶
Check that the outside temperature sensor works correctly.
▶
Check that the exit-air temperature sensor works correctly.
▶
Wait until the outside temperature increases (the product auto-
matically switches on no later than 60 minutes after the tem-
perature increases.).
Outside temperature: > −3 ℃
▶
Check that the exhaust-air fan works correctly.
▶
Check that the supply-air fan works correctly.
1. Press the fault clearance key.
– Fault clearance attempts: ≤ 3
2. If you cannot eliminate the fault with the fault clearance at-
tempt, check that the bypass works correctly.
▶
Check that the heat exchanger works correctly/has no leak-
ages.
▶
Check that the frost protection element works correctly.
▶
Replace the frost protection element.
▶
Check that the supply-air differential pressure sensor works
correctly.
▶
Check that the exit-air differential pressure sensor works cor-
rectly.
▶
Check that the outside temperature sensor works correctly.
▶
Check that the exit-air temperature sensor works correctly.
▶
Check that the supply-air temperature sensor works correctly.
