The option pcb con-
tains a control for a preheater up to 1000 W. The preheater can
be connected to the option pcb without separate control. The
hook-up wire of the preheater must be fed into the appliance;

It is also possible to connect a preheater to the basic pcb of the
CWL-appliance if no option pcb is mounted (see §9.4 of the
installation instructions CWL-300/400).
Control for postheater up to 1000 W
The postheater ensures that the supply air that is blown into
the dwelling can be kept at the preset temperature. That way
additional warmth can be brought into the dwelling. The option
pcb contains a control for a postheater up to 1000 W. The pos-
theater can be connected to the option pcb without separate
control. The hook-up wire of the postheater must be fed into

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
