2 Product description

The function module FM443/CMS 910 is designed exclusively for

use in the control units.

With the FM443/CMS 910 function module, you can control a solar

thermal system with one or two solar consumers (e.g. cylinders).

You can use the following functions after installing the FM443/

CMS 910 function module:

– Change solar control operating mode

– Query operating values of the solar consumer "1" or "2", heat

meter and collector array

– Query yield values over recent days, weeks and years

2.1 Manual switch settings

The various positions of the manual switch have different effects

on the solar circuit or the two solar consumers.

2.1.1 Manual switch (solar circuit 1)

Tab. 1 Manual switch positions

CAUTION!

DAMAGE TO THE SYSTEM

Incorrect use of switch positions 0 and 3can damage the solar

thermal system, and may even destroy individual system

components.

zMake sure that the switch setting is always set to "AUT".

USER INFORMATION

Normally, the manual switch 3should be in the "AUT" position.

Positions 0 and 3are special settings reserved for qualified

personnel only.

Position Effect

Solar heating circuit 1 (solar circuit pump 1) and the

bypass (3-way diverter valve) are switched off.

Solar circuit 1 and bypass are in automatic mode –

this is the standard setting.

Manual mode is enabled.

Solar circuit pump 1 is switched on. The bypass is

not being controlled.

2.1.2 Manual switch (solar circuit selection)

Position Effect

Solar circuit selection is switched off.

The automatic mode of the function module FM443/

CMS 910 (Solar module) is active; this is the

standard setting.

When there is appropriate solar yield, only solar

consumer "2" (solar circuit 2) is heated.

Automatic changeover is disabled.

When there is appropriate solar yield, only solar

consumer "1" (solar circuit 1) is heated.

Automatic changeover is disabled.

Tab. 2 Manual switch positions

USER INFORMATION

If the manual switch is not in automatic mode, a corresponding

message is displayed on the Programmer programming unit and

the LED "module fault" on the module illuminates.

Inform your heating engineer.

USER INFORMATION

The collector protection is ensured with the "Manual ON"

operating mode ("Day mode" key").

USER INFORMATION

The heating circuit which the Programmer programming unit is

assigned to is basically always displayed when the cover of the

Programmer programming unit is closed. If the Programmer

programming unit is not assigned to a heating circuit, then the

lowest installed heating circuit is always displayed.

For further details, please see the technical documentation for

your control unit.
