This adjustment channel depends on the selected flowmeter

type.

Water

If the flowmeter V40 is used, the value is indicated in L/I

V40

("Volume/Imp" is indicated on the display).

1,0 L/I

adjustment range: 0.1 ... 99.9 L/I

If the flowmeter type VTP is used, the value is indicated in

I/L ("heat" appears on the display)

adjustment range: 1 ... 2000 I/L

note:

Pay attention to the indicated l/Imp on your flowmeter!

Adjustment of the subaddress. An individual module address

for one iSolar WMZ can be adjusted. This way it is possible

V40

to use several iSolar WMZ with an individual address in one

1,0 L/I

system. If several iSolar WMZ (up to max. 16) are connected

to a PC or a datalogger, the calorimeters have to be num-

bered serially, starting with 0. The connection sequence at

the VBus

adjustment range: 0 ... 15

Change of the bus mode: active, passive, or cascaded.

Do not change the factory setting if the iSolar WMZ is

1,0 L/I

connected to acontroller with VBus

responds to the bus mode "passive").

Cascaded

Select bus mode "active", if the iSolar WMZ is not connected

to a controller and if data are recorded on a PC or datalogger.

Select bus mode "cascaded", if several iSolar WMZ are con-

nected to a PC or datalogger. The iSolar WMZ modules are

linearily numerated starting with 0 (see 5.9).

• active

• passive

• cascaded

The item "bus master" only appears when subadress "0" and

bus mode "cascaded" have been selected.

Select bus master "No" when several iSolar WMZ modules

Cascaded

are cascaded and used along with a controller.

Yes

Select bus master "Yes" when several iSolar WMZ modules

are cascaded and used without a controller..

In order to offset the sensors, an individual offset can be

allocated to each sensor (range -5.0 K ... +5.0 K, in steps of

Yes

0.1 K).

0,0 K
