Mains-operated instruments:
The supply to mains-operated instruments must
be fused at 6 A. Only specially trained and
authorized personnel are permitted to carry
out the connection.
Moreover attention is to be
paid to the national technical rules, e.g. VDE 0100
in particular.

connections or flange screws resp.
Screw driver slot 0,5x3 (terminal block)
Side cutter (sealing wire, cable binders)
Hex-wrench size 3 for wall adaptor
4. Installation of sub assemblies
Depending on the version PolluStat E can be
used as a heating meter, as a cooling meter or as
a combined heating / cooling meter. Therefore the
text hereinafter includes following terms:
return pipe of heating plants:
colder line
supply pipe of heating plants: warmer line
return pipe of cooling plants:
warmer line
supply pipe of cooling plants: colder line
In case of meters with programmable
installation place
(see related inscription at
integrator) of the flow sensor the required position
(colder line or warmer line) has to be defined.
In order to do this, activate the display by
depressing the red key and releasing it again.
Then each one of the below mentioned options
can be selected one after the other by a short
keystroke. Having set the required position,
remove the bridge between terminal 3 and 4 in the
terminal block.
colder line
warmer line
Attention!
Because of legal calibration regulations the
installation place can only be programmed
once. Therefore be very sure that you have set
the desired position before removing the
bridge.
