Safety Notes
Prior to assembly and
commissioning to avoid injury of
persons and damages of the
devices, it is absolutely necessary to
carefully read and observe these
instructions.
Necessary assembly, start-up, and
maintenance work must be performed
only by qualified, trained and authorized

Definition of Application
❶
PTC2, PM2 is an integrated self-acting
controllers developed for controlling
instantaneous heating of domestic hot
water with heat exchangers. The capacity
of controllers fully cover the needs of
domestic hot water for flats, one family
houses or dwellings and can be mounted
to district heating network directly, to a
block of heating systems or central located
boiler system in a dwelling house.
Strainers istallation
IIt is strongly recommended to install
strainers on both the cold water pipeline
and the district heating supply line.
Assembly

Anvendelse
❶
PTC2, PM2 er en række af integrerede
selvvirkende regulatorer udviklet til
regulering af brugsvand i varmevekslere.
Regulatorernes kapacitet dækker fuldt
ud kravet til brugsvand i lejligheder og
enfamiliehuse og kan monteres direkte i
fjernvarmenettet eller i et centralt placeret
varmesystem.
