PRODUCT DESCRIPTION
Product description
The smart Econ heating system controller was especially developed for single-family houses and
apartment buildings.The goals are the creation of optimum comfort for residents and the greatest
possible ease of use for the system operator.
The smart Econ heating system controller can be operated either via the 4 buttons and the rotary/
push button on the control panel or optionally via existing internet access using a PC, smartphone or
tablet.
The smart Econ heating system controller is a modern system to control the entire domestic technology of single-family houses and apartment buildings.
As many components of domestic technology can be integrated into one single system, there are
many options for system optimization (e.g. energy efficiency, ease of operation, optimization of comfort and maximum coziness).
Outdoor temperature-controlled room heating
When delivered, the controller is designed for purely outdoor temperature-controlled systems.
Depending on the outside temperature, control valves regulate the flow temperature of the respective control circuit according to the set heating curve.
A smart Econ room controller can also be used for remote adjustment.The room temperature influence can be set as an additional reference variable by connecting the room controller.
To take solar radiation into account, several room controllers can be attached (e.g. to separate the
heating circuits on the north and south side).
Self-adjustment / heating behavior
Optionally, heating behavior can be influenced by using a smart Econ room controller.
The inertia of the room is initially assumed to be "average" and later adapted in a learning phase of
about 3 days, during which the desired progression of the room temperature is compared with the
actual development in the main room.In most cases, the optimum setting is found after 3 days.Of
course, this adjustment can be repeated at any time.
This way, heating operation is optimized in terms of comfort, homeliness and energy consumption
independently of the type of heating (underfloor heating system, wall heating or any combination
thereof).
Control of heat generators
In general, all types of heat generators (gas, oil, solid fuel, district heating, heat pumps, ...) can be
integrated into the smart Econ system control.
The heat generators are either enabled by a smart Econ room controller when heat is required or
controlled according to the heat demand flexibly depending on outdoor temperature or constantly
based on tank temperature etc.
The objective of this is to achieve the longest possible switching intervals to minimize the exhaust
emissions by reducing the number of startups and at the same time to increase the heat generator's
service life.
smart Econ - emz-HCW - 18011611
PRODUCT DESCRIPTION
smart EconControl options
If a room controller is used, the flow temperature of the associated heating circuit can be raised
briefly for rapid heating if there is a large deviation in the room temperature.The flow temperature is
reduced during setback operation.
If there is no heat demand, the pumps of the relevant heating circuits are switched off.
Water heating
Different preset temperatures can be defined for different times of the day.This allows for energy
savings in general, as the hot water is only controlled to the required temperature in the desired time
range.
Depending on the hydraulic system, two temperature sensors (top and bottom) can be defined (e.g.
switch on when the storage tank becomes "cold" at the top, and switch off when the lower part is
"warm").
A boiler priority circuit is also supported.
Anti-legionella function
To kill germs, the thermal disinfection program is carried out once a week every Monday.The
domestic hot water is heated to 63°C.
Solar heating system
A configurable differential temperature control ensures that the solar heating system generates as
much heat as possible.
You can load several heat consumers (buffer, boiler, swimming pool, etc.) with different temperature
levels.
smart Econ Transmission technology
The components of the heating system smart Econ controller can be networked together.This way,
data is transferred via the fieldbus system CAN (Control Area Network).
“CAN bus line” on page 15
Distance communication via the Internet
The smart Econ heating system controller features an integrated Ethernet interface. that can be
used to connect it to the Internet.The Ethernet makes remote switching possible.The user can also
download the configuration, operating statuses, archive and software updates from the network.The
information messages can be sent directly via e-mail, free access to smart Econ Cloud provided.
“Internet-based network” on page 55
Remote maintenance via smart Econ Cloud
The smart Econ heating system controller can be remotely maintained via the smart Econ Cloud of
the company emz via the Internet. The current operating status of the system can be queried and
the configuration can be changed.
12 smart Econ - emz-HCW - 180116
PRODUCT DESCRIPTION
Cloud access
After one-time authentication using the TAN procedure (TAN key/ID code not included) and successful logon, the smart Econ Cloud provides remote access to the controller.Whether PC, Tablet or
Smartphone, the menu interface adapts automatically.
Access via: www.smarteconcloud.com
“smart Econ Cloud setup” on page 143
Information and control
The current status of the controlled pumps, valves and boiler can be read off at a glance from the
graphic system diagram.This is the graphic of the selected system that is also visible on the controller.
In addition to the current system data, the controller’s status messages, error messages and data
archive are available for viewing.In addition, the various operating modes can be selected and individual parameter values of the controller can be changed.
The recordings stored in the controller are processed graphically and can also be displayed together
over a longer period of time.
Safety
Access to the controller is protected in three ways.First, the ID code to be entered at the first login
and a randomly generated 20-digit authentication code - both codes will be checked internally at
each access later on.After logging in, the 6-or-more character, individual user password forms the
third level of protection.
Initial access is activated via a secure TAN procedure.
Data protection
The protection of personal data is our top priority.For identification purposes, no personal data other
than the name and a valid e-mail address is collected from the operator when registering.

“Internet-based network” on page 55
• 1 USB interface inside the housing (Micro-USB-B)
“Installation and connection” on page 45
smart Econ Room controller
The smart Econ room controller determines the current room temperature.
The desired room temperature can be readjusted using the setting wheel.In
addition, the operating mode for the assigned heating circuits can be changed
via the end positions of the setting wheel:
In the end position (+) a permanent party mode (always heat)
and in the end position (-) a permanent setback function.
CAN bus line
Connect the individual system components in series with a 4-pole cable, the CAN bus line.
The CAN bus line merely has to be connected from one component to the next, which significantly
reduces the installation effort.
Data is transferred via the fieldbus system CAN (Control Area Network).

As this is set directly at the smart Econ room controller, each user can control the entire heating system for the respective area without requiring any special knowledge of the heating installation or its
control system.
Operating mode ›DAY‹
Time programs are not considered.The highest room temperature setpoint entered for the respective heating circuit is used.
Operating mode ›NIGHT‹
The time programs are not considered, the temperature is always controlled to the room temperature setpoint entered for setback operation.The temperature is also controlled to this setback room
temperature on individual programmed holidays as well as on the last holiday of a holiday period.
See “›HOLIDAY PERIODS‹ menu” on page 35
Operating mode ›FROST PROTECTION‹
