Power modules for heating and cooling meters
PolluTherm / PolluStat E / PolluFlow
1. Use of the power supply modules
There are two different calculator housings with which these same plug-in units can be used namely:
Calculator housing 1 (PolluTherm until 2007, PolluStat E and PolluFlow until 2009) indicated by a
lid that can be opened sideways which is closed by a black plastic latch
Calculator housing 2 (PolluTherm from 2007, PolluStat E and PolluFlow from 2009) indicated by
a lid that is opened from bottom to top with two locking latches on the two bottom corners.
The assignment of the modules for the calculators can be taken from the tables.

in the delivery
2. Safety instructions
The above mentioned modules may only be used for the devices provided for in the list as otherwise
the modules or the heat meter could be damaged
Exchanging batteries against power supply units requires a careful handling of the batteries.
Batteries must not be recharged, short-circuited, put in contact with water or exposed to
temperatures of more than 80 °C
Power modules for calculator housing 1 have an internal back-up battery. The same safety
instructions as mentioned in the previous point apply
Power modules for calculator housing 2 do not have an internal back-up battery anymore; they can
be stored indefinitely.
Batteries and electronic waste may only be disposed at suitable collection centers for professional
waste disposal
Connecting network modules may only be done by persons authorized and trained for that purpose.
Furthermore the generally accepted rules of technology and VDE 0100 in particular have to be
observed.
Power module must be fed from supplies fused at 6 A protection
Before exchanging a power module the existing power module has to be switched off
When the power module is damaged it has to be scrapped and replaced with a new one

3. Retrofitting or replacement of a power module
3.1. Opening of the calculator housing
Remove the lower user seal from the housing
Calculator housing 1: Open the housing cover by opening the black housing latch
Calculator housing 2: Open housing by pressing both closing clips at the two bottom corners
3.2. Removal of battery and insert of power module
Calculator housing 2:
PolluStat E, PolluFlow: before the supply battery is removed the calculator module has to be
dismantled from the calculator. Unscrew only the screw from the plastic cover on the right side under
the KK1 seal (user seal) (picture 3). Pull out the calculator module. The seals in the middle and on
the left side may not be removed (invalidation of metrological sealing)!
PolluStat E, PolluFlow: plug on the back-up battery AA 3,6V (68504900) to the backside of the
calculator module (picture 4) (JST plug). The battery is required for date back-up and short-term
emergency operation in power failures. In the PolluTherm the back-up battery is soldered-on to the
circuit board as standard
Calculator housing 1 and 2:
Either unplug the battery connection plug and remove the battery from its position or remove the
shorting plug (only used with Pollutherm, Type Pt500)
For disposal note safety instructions, point 2
3.3. Installation of power supply unit
Plug the connection plug of the power module in the socket and insert the power module in the
designated recess of the housing. The connection plug is polarized so inversion of the plug is not
possible.
In order to connect cables a spare rubber moulding has to be removed from the calculator housing 2.
Route the cable through the rubber moulding and make a pull relief with the provided cable clip. With
calculator housing 1 the cable has to be routed through the cable clamps and fixed
Please ensure that the cable of the connection plug is not pinched by the calculator cover
Close the calculator lid and seal with the provided self lock seal
For detection of the power module it is necessary that the device is connected to the power system
for at least one minute
Through a connector encoding the M-Bus credit automatically turns off when a power supply unit is
installed

3.4. Connection to electricity network
The power modules have a connecting cable of 1 m length.
The cable may only be connected to a 230V AC network by a person authorized and trained for that
purpose
The connection should be made on a junction box
24 V AC power modules are connected to power supply systems from controls or central control
technologies. These modules must not be connected to 24 V DC direct voltages
Since heat meters in calculator housing 1 do not count during a power supply interruption a reliable
power supply is important. In the event of a power failure all stored values are retained and the
internal clock continues running via the back-up battery. Heat meters in calculator housing 2
continue running for a limited time after a power failure. M-Bus communication, however, can be
limited.
