1. INTENDED USE

The FRG3020-W manifold control unit is used for load-dependent control of the supply temperature in floor and
panel heating/cooling systems.

The supply temperature is controlled by the integrated HEAT/COOL controller dependent on the outside temper-
ature using a selectable heating/cooling curve. The steepness of the curve can be selected according to local
conditions ( Controller installation and operating instructions).

The FRG3020-W can operate a heating system which is set to suit the individual requirements of an apartment
or individual domestic or business areas. The integrated CC-HC climate controller has a 7 day program with
9 ex-works fixed integrated standard programs as well as 4 programs which can be set as required by the user.

A room temperature controller can optionally be connected to the CC-HC climate controller. Suitable cable based
or radio-controlled programmable room thermostats are available as accessories. These enable heating system
operation to be optimised based on the usage pattern of a reference room.

The control unit can be mounted directly onto the right or left hand side of the round pipe heating circuit manifold with
a 1" male thread with a centre-to-centre dimension of 210 mm. It is provided with G 1" union nuts for this purpose.

The control unit is intended for use in dry areas in either domestic or business premises. It is normally installed in
the boiler room or in a manifold cabinet.

Check in the relevant regulations for improper use before commissioning.
