The “Sime Sub HE/DHW” are a heating substations suitable for apartments and single-
family houses that are directly or indirectly connected to a heating network.
All internal wiring is factory fitted and the plumbing is well arranged. Thanks to its com-
pact size and low weight, the unit is convenient to fit into limited space. In new buildings,
it demands less space than traditional substations. It can also be connected to low tem-
perature heating systems.
The substation has two thermostatic mixing valves that supply the required temperatures
for central heating and domestic hot water. Domestic hot water is heated separately in a
high-capacity heat exchanger (see technical features).
The “Sime Sub HE/DHW” meets stringent demands for long-term performance. The heat
exchanger plates are manufactured in acid-resistant stainless steel. All components are
easily accessible for inspection and service.

The differential pressure regulator keeps the difference in pressure found in two points of
a hydronic circuit at a constant level, corresponding to the set value. The device is inserted
in the circuit return pipe and is connected, by way of a capillary pipe, to the flow pipe. It is
used in variable flow rate systems, with motorised valves, to limit the increases in differen-
tial pressure that are created when these valves are closed, either totally or partially. The
action of the device is proportionate to the variation in differential pressure that is created,
to restore the ∆p conditions set.

The Energy meter is the device that stores the amount of heat used by the temperature
difference between HMS and HMR and the amount of water used route under its control.
The installation of the heat counters must comply with the normative reference EN•
1434, parts 1 + 6 , and I.E.E wiring regulations.
This heat counter is manufactured according to the current safety regulations. The•
maintenance operations must be made by authorized personnel only.
Breakage of any of the seals on the heat counter will invalidate the warranty.•
A minimum separation of 20 mm must be maintained from any electromagnetic de-•
vice, and a minimum of 50mm from any other electrical wiring.
The cables to the temperature sensors must not be tightly coiled, lengthened or•
shortened.
Clean using a dry cloth.•
When multiple heat counters are installed it is important to observe the wiring polar-•
ity.

Infrared (IrdA Port)
For data transfer from microCLIMA to the computer, it is necessary to wire an optical head
onto the serial gate of the computer. The optical head and the necessary software are
available upon request as optional. The IrdA port is activated with an appropriate key. After
60 seconds of inactivity, the gate will shut-off automatically.
M-bus
M-Bus interface is available upon demand (optional). When using this system, checking of
the main data and the measurements cannot be altered. The protocol is in compliance with
Standard EN1434-3 and with Standards IEC 870.
Baud: standard: 2400 Bd. It is important to outline the typology M-Bus (length of the wiring
cables, cross sections of the cable) has to correspond to the baud unit of the heat counter.
During the M-Bus communication, it is not possible to use the other communication in-
terfaces of the device (key or IrdA), and vice versa. Note: the heat counters are battery fed,
and that’s the reason why the simultaneous communications are so limited. In a M.-Bus
net of 250 heat counters, for every tester no. 24 demands per day are possible. If a small
number of demands and/or a small number of heat counters are wired to the bus, the un-
used quantity of available demands is stored onto the device.
The life battery of the battery depends on the quantity of data exchanged. Its minimum life
is 6 years.
Output signals
The device is equipped with a signal outlet fed by electronic inputs, to be required when
the PO is submitted.
The contact is type: class A0, according to Normative EN1434, and produces the counting
impulses of the heat counter. The outlet of the impulses closes in relation to the measured
volume of the appliance (see data plate) for a duration of 125 ms. When the impulses
through the outlet are many, the gap time between the impulses is of 125ms. Should the
nominal data and the edge of the contact be taken into consideration, the end user is free
to set-up the data about the impulses in a wide range of options. The contact (fig. 6) can be
wired by means of a large number of devices, aimed to get the outlet data.
The minimum duration of the battery for the heat counters, equipped with outlet impulses,
is of 6 years plus 1.

The energy meter is used for measurement of both heat and cooling in all water based
plants. The meter is simple to read and verify. The energy meter receives volume pulses
from the connected flow meters and calculates the energy for every predetermined water
volume. The energy calculation includes temperature measurements in flow and return as
well as correction for density and heat content according to EN 1434.
The energy meter is calibrated at factory and it is available on request.

Electrical
wiring
“Sime Sub HE/DHW” is supplied with an electric cable. Should this require replacement,
it must be purchased exclusively from SIME. The electric power supply to the substation
must be 230V - 50Hz single-phase through a fused main switch, fitted with a 3 A fuse, with
at least 3 mm spacing between contacts. Respect the L and N polarities and the earth
connection.
This must be carried out by a qualified electrician.The wiring conforms to the applicable rules
for CE marking and has undergone electrical safety testing and function testing
(fig. 10).
SIME declines all responsibility for injury or damage to persons, animals or property,
resulting from the failure to provide for proper earthing of the appliance.
Before any work is done on the substation, it must be isolated from the power supply by
turning off at the external switched supply.

The boiler heats the water, which is distributed to multiple buildings through the distri-
bution network. When it is in substation heating exchanger, water to water transfer net-
work in the distribution system inside the building the necessary heat for space heating
and domestic hot water production. At the end of this process, the water, now cooled,
returns to Central to be reheated.
