MULTICAL® 402
Energy Mesurement
MULTICAL® 402 functions in the following wy:
The flow meter registers the mount of district heting wter in m³ (cubic
metres) circulting through the heting system.
The temperture sensors plced in inlet nd outlet pipes register the
cooling, i.e. the difference between input nd output tempertures.
MULTICAL® 402 clcultes consumed energy bsed on volume of district
heting wter nd cooling.
Redings
When the top front key is ctivted,  new reding ppers.
The lower front key displys historicl redings nd verge vlues.
Four min. fter the ltest ctivtion of the front key the meter utomticlly
switches to consumed energy.

1 Generl informtion
Red this guide before instlling the meter.
In cse of incorrect mounting Kmstrup’s gurntee obligtions no longer
pply.
Plese note tht the following instlltion conditions must be obeyed:
- Pressure stge: PN16/PN25, see mrking. The flow
sensor mrking does not pply to
enclosed ccessories
- Pressure stge, Kmstrup
sensor set type DS: PN16
- Pressure stge, Kmstrup
stinless steel pockets: PN25
At medium tempertures bove 90 °C in flow sensor, use of flnge meters is
recommended, nd the clcultor should be wll-mounted.
2 Mounting of temperture sensors
The temperture sensors used to mesure inlet nd outlet tempertures re
 mtched sensor set tht must never be seprted.
MULTICAL® 402 is by defult supplied with mounted temperture sensors.
According to EN 1434 the cble length must not be chnged. If necessry,
sensors must lwys be replced in pirs.
One sensor is mrked with  red sign nd must be instlled in the inlet pipe.
The other sensor is mrked with  blue sign nd must be instlled in the
outlet pipe (see prgrph 8, pge 17).
Note: The sensor cbles must not be pulled. Be wre of this in cse of
binding the cbles.

2.1 Pocket sensor set
Preferbly, sensor pockets must
be mounted in tee-pieces or in
45° lterl Y-pieces. The tip of the
sensor pocket must point ginst
the flow direction nd be plced in
the middle of the wter flow.
Temperture sensors should be
inserted to the bottom of the
pockets. If  short response time
is required, “non-hrdening” het
conducting pste cn be used.
Push the plstic sleeve on the
sensor cble into the sensor pocket
nd secure the cble with the
enclosed M4 seling screw. Fsten
the screw with your fingers only.
Sel the pockets using sel nd
locking wire.

Short direct sensors cn be mounted
in specil bll vlves or in specil tee-
pipes, both with threds up to R1 nd
built-in M10 union for the short direct
sensor.
For mounting in existing heting
instlltions with stndrd ngle tees
Kmstrup A/S cn supply R½ nd R¾
brss nipples fitting the short direct
sensors.
Short direct sensors cn lso be
fitted directly into ll Kmstrup’s
ULTRAFLOW® vrints with G¾ nd
G1 threds on the meter cse. Fsten
the brss unions of the sensors lightly
(pprox. 4 Nm) using  12 mm fce
wrench nd sel the sensors with sel
nd locking wire.
3 Informtion codes ”INFO”
MULTICAL® 402 constntly monitors  number of importnt functions. If
there is  serious error in the mesuring system or instlltion,  flshing
“INFO” is displyed, nd n info code cn be red by ctivting the top front
key until the mesuring unit displys “INFO”. The info code is visible s
long s the error exists, unless the meter hs been specilly configured for
”mnul reset of info codes”. When n info code hs existed for n hour, it is
sved in the info log.

4 Mounting of flow sensor
Prior to instlltion of the flow sensor, the system should be flushed nd
protection plugs/plstic diphrgms removed from the flow sensor.
Correct flow sensor position (inlet or outlet pipe) ppers from the front lbel
of the MULTICAL® 402. The flow direction is indicted by n rrow on the side
of the flow sensor.
4.1 Mounting of glnds nd short direct sensor mounted in
MULTICAL® 402 flow prt
The short direct sensor from
Kmstrup cn only be mounted in
PN16 instlltions. The blind plug
mounted in the MULITCAL® 402 flow
prt cn be used in connection with
both PN16 nd PN25.

5 Mounting the clcultor
The MULTICAL® 402 clcultor cn either be mounted direct on the flow
sensor (compct mounting) or on  wll (wll mounting).
5.1 Compct mounting
Compct mounting mens tht the clcultor is mounted direct on the
flow sensor. Hving been mounted, the clcultor is seled with sel nd
locking wire. In cse of strong condenstion (e.g. cooling pplictions) we
recommend wll mounting of the clcultor. Furthermore, MULTICAL® 402
must be the condenstion protected version.
By defult the fitting is plced t
the bottom of the flow sensor nd
the clcultor cn be mounted s
shown.
85 mm
If  minimum depth of instlltion is
required (G¾ nd G1), the fitting cn
be removed from the bottom of the
flow sensor A nd mounted on the
side of it. This mens tht the plstic
box on the flow sensor now points
downwrds nd tht the clcultor
is mounted on its side B.

5.3 Mounting position of clcultor
If the flow sensor is instlled in 
humid or condensing environment,
the clcultor must be mounted
higher thn the flow sensor.
6 Power supply
MULTICAL® 402 cn be powered by  built-in lithium bttery or by n integrl
24 VAC or 230 VAC mins module.
The two wires from bttery or mins module re mounted in the clcultor
vi  two-contcts connector.
6.1 Bttery supply
MULTICAL® 402 is connected to  lithium bttery, D-cell or 2 x AA-cells.
Optiml bttery lifetime is obtined by keeping the bttery temperture
below 30 °C, e.g. by wll mounting.
The voltge of  lithium bttery is lmost constnt throughout the lifetime
of the bttery (pprox. 3.65 V). Therefore, it is not possible to determine the
remining cpcity of the bttery by mesuring the voltge.
The bttery cnnot nd must not be chrged nd must not be short-
circuited. Used btteries must be hnded in for pproved de-struction, f.inst.
