The HERZ-DE LUXE Substation
Compact substation for radiator heating and drinking water systems, utilising
a countercurrent heat exchanger made of stainless steel. In standby mode a
temperature regulated bypass guarantees available primary fl ow at the heat
exchanger. Central controller for hot water only operates as a pressure drop
is detected when a hot tap is opened. Safety against scalding by integrated
HERZ-thermostatic mixing valve. Differential pressure controller with fi xed DP
fi tted on the heating circuit can be operated as a zone valve with a thermo
electric drive for regulating the room temperature. Heat meters can be retrofi
tted as required. Strainer with fi ne-mesh screen is also fi tted on the heating
circuit to protect the DP controller. Premounting unit with ball valves for the
later connection of the substation. Usable as in- or onwall substation with
separate cover. Necessary inwall adjustment unit or external cover have to
be ordered separately. Static pressure of cold water 3.5 bar at minimum.
Hot water fl ow rate 14 l/min (10/52 °C). Max. working pressure 10 bar. Max.
riser temperature 90 °C. The HERZ premounting unit for the HERZ-DE LUXE
substation 1 4008 04 has to be ordered separately.

The HERZ DE LUXE light Substation
Compact substation for radiator heating and drinking water systems.
Individual module DE LUXE Light. Individual module for DHW, water and
space heating. In standby mode a temperature regulated bypass guarantees
available primary fl ow at the heat exchanger. Central controller for hot water
only operates as a pressure drop is detected when a hot tap is opened.
The module includes a HERZ-Control valve incorporating a thermostat with
immersion sensor,which maintains a maximum DHW temperature, a strainer
with fi ne mesh is also fi tted. It also provides adapters for installation of
fl owmeter, water- and heat meters. Individual module HERZ DE LUXE Light
can be combined with the following sets of equipment:

The HERZ-STANDARD Substation
Compact substation for radiator heating and drinking water systems, utilising
a countercurrent heat exchanger made of stainless steel. In standby mode a
temperature regulated bypass guarantees available primary fl ow at the heat
exchanger. Central controller for hot water only operates as a pressure drop
is detected when a hot tap is opened. Safety against scalding by integrated
HERZ-thermostatic mixing valve. Differential pressure controller with fi xed DP
is fi tted on the heating circuit. Heat meters can be retro-fitted as required.
Strainer with fi ne-mesh screen is also fi tted on the heating circuit to protect
the DP controller. Connection by premounted ball valves. Usable as in- or
onwall substation with separate cover. Necessary inwall adjustment unit has
to be ordered separately. Static pressure of cold water 3.5 bar at minimum.
Hot water fl ow rate 14 l/min
(10/52 °C). Max. working pressure 10 bar. Max. riser temperature 90 °C.
