Chapter 11
11.6 Connecting external switch contact (only possible for Ubiflux+)
An external switch contact (e.g. switch or relay contact) can be connected to the Ubiflux+. This external switch contact can be con-
nected to connections no. 1 and no. 2 of the 9-pole connector; this 9-pole connector is directly accessible at the top of the appliance
(also refer to §11.1).
If a second input is required as external switch contact, if necessary connections no. 3 and no. 4 of the 9-pole connector, which as
standard are preprogrammed as 0-10 V input, can be reprogrammed as second input switch contact. Changing step number 21 from
"1" to "0" or "2" makes this 0-10V input an NO contact or NC contact respectively. On application of to switch inputs, switch contact 1
(9-pole connector no. 1 & no. 2) always takes precedence over switch contact 2 (9-pole connector no. 3 & no. 4).

When connections no. 3 and no. 4 of the 9-pole connector are programmed as switch input 2, step number 24, 25 and 26 can be used
to set the various modes the same as for contact input 1. When closing contact input 2, the display shows the text "CN2".

modes for the supply and exhaust fans; dependent on the set-
ting of step numbers 19 and 20, the supply and exhaust fans
can run at various flowrates (highest flowrate is shown on the
display).
