The base load can be switched on and off
with S2.
●
Case 1: Fan is stationary. If S2 is activated
(S2 = On), the unit switches immediately
to base load, without considering the
preset start delay. If S2 is activated again,
(S2 = Off), the unit switches immediately
off, without considering the preset overrun
time.
●
Case 2: The unit is running at base load
level (S2 = On). If the room lighting is
switched on (S1 = On), the fan switches to
nominal load after the preset start delay of
0 to three minutes which can be set using
a jumper.
After the room lighting is switched off, the
fan continues running for an overrun time
of up to 15 minutes. The overrun time can
be set to between 0 and 15 minutes using
a jumper. Then the fan switches back to
the base load level.
For setting the start delay and overrun
time
chapter 14.1. Note the overrun
time stated on the general building
approval.
●
Case 3: Fan is stationary. If the room
lighting is switched on (S1 = On), the fan
switches to nominal load after the preset
start delay of 0 to three minutes which can
be set using a jumper.
After the room lighting is switched off, the
fan continues running for an overrun time
of up to 15 minutes. The overrun time can
be set to between 0 and 15 minutes using
a jumper. Then the fan switches off.
For setting the start delay and overrun
time
chapter 14.1. Note the overrun
time stated on the general building
approval.
