ER 60 GVZC EC
Standard switching
The unit permanently runs at least at base
load. The base load level cannot be switched
off manually.
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 7.1. Note the overrun time stated
on the general building approval.
