20. SETTING FISCAL PARAMETERS & PROGRAMMING ALARMS

The ﬁscal parameters have a direct inﬂuence on the metering of the whole system; in order to change these para-

meters it is necessary to open the seals on the unit (see section 5) and take certain actions inside the meter.

The parameters are:

– TYPE OF OUTPUT, WEIGHT & INSTALLATION POSITION OF THE VOLUMETRIC METER FOR THE VECTOR

FLUID FOR HEATING/COOLING.

To conﬁgure the type of volumetric meter for vector ﬂuid, do as follows:

• Position SWITCH 7 (see section 20.3)

• Position JUMPER P4 (see section 9)

– ANY ADJUSTMENTS TO THE FOUR METERINGS.
– THRESHOLD OF MAXIMUM FLOW FOR THE VECTOR FLUID (if the relative alarm is required).
– THRESHOLD NUMBER OF OPERATING HOURS BEFORE CARRYNG OUT MAINTENANCE & REPLACE-

MENT Of BATTTERY.

Dip switches for the settings

By removing the electronic unit and turning it upside down you can see at the bottom on the right the dip switches

for the settings

Switch number 4: “Enabling COOLING"

With this switch you can decide whether to have metering of heating only (calories) or metering of heating (calories)

and, at the same time, of cooling (frigories), as described in section 16.4.

= METERING HEATING & COOLING

= METERING HEATING ONLY

20.

Switch number 7: choice of “volumetric meter for vector ﬂuid, heating and/or cooling between output LITRES PER

PULSE & PULSES PER LITRE”

= LITRES PER PULSE: all the volumetric turbine meters (mechanical), the volumetric magnetic

meters and similar, and some models of ultrasound meters.
Check also the position of jumper P4 (see page 4)

= PULSES PER LITRE: generally ultrasound volumetric meters; however, not all are of this type and

so it is advisable to examine the speciﬁcations of the volumetric meters to ensure they are coupled

correctly to the integrator.
Check also the position of jumper P4 (see page 4)
