An external switch contact (e.g. switch or relay contact) can be connected to the . 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).
Modifying step number 18 enables, when closing the input ex-
ternal switch contact 1 no. 1 and no. 2, setting five different
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).
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”.
1) Bypass function active conditions: - Outdoor temperature is higher than 10°C
- Temperature atmosphere is at least lower than temperature from dwelling
- Temperature from dwelling is higher than the preset bypass temperature (step no. 5).
