meters must also be set on the control panel. Setting or mo-
difying parameters is described in § 4.2.1 and 4.2.2.
4.3.1 Switch input incidents
Parameters P1 and P2 must be set on the control panel.
P1 represents the air quantity of the input fan and P2 re-
presents the air quantity of the output fan. When the switch
contact is made, both fans will run at the preset air quanti-
ties P1 and P2. The setting parameters as shown in § 4.2.4.
4.3.2 Switch input bedroom valve
Parameters P3 and P4 must be set on the control panel. P3
represents the additional air quantity of the input fan and P4
represents the additional air quantity of the output fan. When
the switch contact is made, both fans will run at the air quantity
of the 3-way switch, increased by the preset air quantities P3
and P4. The setting parameters are shown in § 4.2.4.
4.3.3 Programmable make contact 1
Parameters P5, P6 and P7 must be set on the control panel. P5
indicates where make contact 1 must be linked to, P6 and P7
indicate what the air quantity must be for the input and output
