Connecting External Switch Contact (Only Possible For Ubiflux +) - ubbink Ubiflux W300 + Installation Instructions Manual

Chapter 11
11.7 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 9-pole connector X15; this 9-pole connector is directly accessible at the rear of the top without
having to dismount the display cover (see also §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 X15, which
as standard are preprogrammed as 0-10 volt input, can be reprogrammed as second input switch contact. Changing parameter 21
from "0" to "1" will turn this 0-10 V input into an input make contact. When using two switch inputs, switch contact 1 (X15-1 & X15-2)
always takes priority over switch contact 2 (X15-3 & X15-4).
Modifying parameter 18 enables, when closing the input external switch contact 1 X15-1 and X15-2, five different situations for the
extract fan to be set; dependent on the setting of parameters 19 and 20, the supply and extract fans can run at various flow rates
(highest flow rate is shown on the display).

When connections X15-3 and X15-4 are programmed as switch input 2, parameters 24, 25 and 26 can be used to set the various
situations the same as for contact input 1. When closing contact input 2, the display shows the text "CN2".
