System description
S. 9
2System description
Fig.: 1 System overview heatapp!
heatapp! is a system that lets you control your heating system via app. From anywhere. At any time. heatapp! allows the
definition of individual switching times as a repeating program as well as setting three temperature levels—comfort
temperature, economy temperature and setback temperature—for each room or group of rooms. A temporary adjustment of
the temperature can be activated via the wheel and the scenes Holiday, Walk, Party, Shower, Boost and Standby.
In conjunction with heatapp! gateway and the wireless components, heatapp! is turned into a highly efficient individual room
control, which determines the heat requirement of each room and regulates the heat distribution.
The three user roles to be selected are “User”, ”Owner” and “Expert”. These roles have different operating and viewing rights,
allowing each user to be individually assigned his or her area to be controlled.
2.1 Application variants
heatapp! supports several options on how to connect to the energy producer. This results in various application scenarios. These
scenarios are shown below:
heatapp! as remote control when connecting the system to the energy generator via OpenTherm bus or T2B bus for THETA
controllers. In order to control this setting, the outside temperature is used to determine the heat demand. The available
heating circuits (without room station) are displayed as room groups.
heatapp! as reference room controller when connecting the system to the energy generator via OpenTherm bus or T2B
bus for THETA controllers, 0 - 10 V connection or switching contact for a heating circuit. The temperature is regulated based
on the temperature determined in a reference room by using the hard-wired room sensor heatapp! sense-wire. The heat
demand is calculated by using the difference between the determined actual temperature and the set target temperature
and is transmitted as a heat request to the energy provider. All rooms connected to this heating circuit are adjusted to the
temperature of the reference room.
heatapp! as controller for a single room when connecting the system to the energy generator via OpenTherm bus or T2B
bus for THETA controllers, 0 - 10 V connection or switching contact. The temperature is controlled based on the actual

System description
S. 10
temperature determined in each room. When the setpoint temperature is reached, the heat request to the energy provider
is stopped, so that it can be turned off. In order to determine the actual temperature, the heatapp! radio components and
the heatapp! gateway are required.
heatapp! as individual room controller without connection of the heatapp! base to the energy generator. The heatapp!
base assumes the heat distribution based on the heat demand of each individual room. The heatapp! gateway transmits the
temperatures of the room sensors to the heatapp! base. As long as there is a heat request, the valves of the corresponding
rooms are opened. When the setpoint temperature is reached, the valves close. The temperature is regulated
independently of the heat generation. Therefore, only the available heat can be distributed.
2.2 The Z-Wave wireless system
The Z-Wave wireless system is a wireless communication standard specially for use in the smart home sector. The wireless
communication is optimised for low energy consumption and maximum communication safety.
Z-wave uses two-way communication with acknowledgement. Only confirmed telegrams are classed as sent successfully. If a
communication error occurs, the transmit process is repeated three times.
Z-Wave has implemented the feature of a mesh-networking technology in which every mains operated device can send
telegrams to other devices in its own network. The resultant meshed network is controlled by heatapp! gateway and the routes
updated upon changes to the network.
heatapp! floor and heatapp! repeater are constantly active in the wireless network and can therefore serve as Z-Wave routers.
Battery operated devices such as heatapp! drive and heatapp! sense are mainly inactive, only waking periodically to receive and
send commands. They cannot be used as routers.
Note
heatapp! Z-Wave radio components can be included in any Z-Wave network. The operation depends on the respective
system and can therefore differ from heatapp!
All 230 V radio components within the Z-Wave network have repeater functions for other Z-Wave products and help to
increase the reliability of the network.

heatapp! Components
S. 11
3heatapp! Components
3.1 heatapp! base
heatapp! base is the central control and regulation unit of the system. heatapp! base can communicate with the energy
generator via the switching contact, 0 - 10 V and Open Therm interfaces of an existing heating system and transmit the heat
demand to the energy generator. heatapp! base also communicates with the heatapp! gateway via the home network. As an
option, and in conjunction with heatapp! sense-wire, it can be used as a reference room controller. Without room temperature
detection it can be used as a remote control of an OpenTherm energy generator.
3.2 heatapp! base T2B
Starting with version V3.X, heatapp! base T2B is the central control unit in conjunction with the THETA controller. The heatapp!
base T2B can communicate with the energy generator via the switching contact, 0 - 10 V and T2B bus interfaces of an existing
heating system and transmit the heat demand to the THETA controller. The heatapp! base T2B communicates with the heatapp!
gateway via the home network. As an option, and in conjunction with heatapp! sense-wire, it can be used as a reference room
controller. Without room temperature detection it can be used as a remote control of a THETA controller.
Note
In the following text, heatapp! base is always to be understood as heatapp! base and heatapp! base T2B, unless the
difference is explicitly pointed out.
3.3 heatapp! sense-wire
heatapp! sense-wire is a wired temperature sensor for measuring the current temperature of the reference room in the
heatapp! base/T2B. The device is mounted on the wall and connected to the E1 input of the heatapp! base/heatapp! base T2B.
heatapp! sense-wire is used for control of a heating circuit based on the reference room principle.
3.4 heatapp! gateway
heatapp! gateway is the main wireless interface of the single room heat regulation. heatapp! gateway wirelessly sends and
receives information to all radio components for control of the radiators (heatapp! drive), underfloor heating system
(heatapp! floor) and for room temperature measurement (heatapp! sense and heatapp! sense control) and serves as a message
interface for heatapp! base/heatapp! base T2B and heatcon! EC.
heatapp! gateway communicates with the radio components, which are located in the individual rooms via the Z-wave wireless
protocol. Communication with heatapp! base / heatapp! base T2B / heatcon! EC takes place via the home network of the
customer.
3.5 heatapp! drive
heatapp! drive is a wireless actuator for flow-controlling a radiator.
The heatapp! drives can be fitted to all common makes of valve with an M30 x 1.5mm connection or RA adapter. For valves with
RA/V and RA/VL connection, we offer a corresponding adapter. Other adapters are available through the trade. A heatapp! drive
communicates wirelessly with the heatapp! gateway.
3.6 heatapp! floor
heatapp! floor is a control system for underfloor heating systems and -heating coils. Up to eight channels each with up to three
thermoelectric actuators can be controlled. A maximum of 24 thermoelectric actuators can be connected. heatapp! floor
communicates wirelessly with the heatapp! gateway. heatapp! floor also contains an integrated repeater to improve the
wireless range of other heatapp! radio modules.

heatapp! Components
S. 12
3.7 heatapp! single floor
The heatapp! system operates a Z-wave component available on the open market, to be able to execute heating-relevant
functions. Only those components which we declare as having been heatapp! checked can be assigned a room in heatapp! and
consequently adopt a heating-relevant function. Switchable wireless sockets and in-wall relays are used to control electrical
heaters, such as fan heaters, infrared heaters or panel heaters. These are detected in the system as a heatapp! single floor unit.
A list of heatapp! checked components from other manufacturers can be downloaded from
https://heatapp.de/service/downloads/.
3.8 heatapp! sense
The heatapp! sense is a room sensor for measuring the current temperature in rooms with underfloor heating. Thanks to
wireless technology, the position of the heatapp! sense in the room can be flexibly selected; nevertheless is must not be covered
to ensure it receives accurate temperatures. The heatapp! sense communicates wirelessly with the heatapp! gateway.
3.9 heatapp! sense control
The heatapp! sense control is used to measure the current temperature and to display the air humidity, as well as the desired
temperature setting (setpoint) for a room. Thanks to the battery-operated wireless technology, the position of the heatapp!
sense control in the room can be flexibly selected; nevertheless is must not be covered to ensure it receives accurate
temperatures. The heatapp! sense control communicates wirelessly with the heatapp! gateway.
3.10 heatapp! repeater und heatapp! repeater S
heatapp! repeater and heatapp! repeater S are used to improve the wireless coverage in a system. If one or more radio
components are inaccessible, a heatapp! repeater is positioned between the heatapp! gateway and the radio component that
cannot be reached thereby improving the wireless coverage. In very large rooms or buildings with strongly attenuating building
materials (e.g. reinforced concrete), it may be necessary to use stronger repeaters. In this case, the heatapp! repeater S is used.
3.11 Window sensor
The heatapp! system operates a Z-wave component available on the open market, to be able to execute heating-relevant
functions. Only those components which we declare as having been heatapp! checked can be assigned a room in heatapp! and
consequently adopt a heating-relevant function. Z-wave window contacts are used to control window shutdown of the heating
system in accordance with the configured function. In this way, control is more efficient because the window shutdown function,
dependent on configuration, switches off the heating until the window is closed again. To enable this configuration, ensure
components are heatapp! checked before purchasing. A list of heatapp! checked components from other manufacturers can be
downloaded from https://heatapp.de/service/downloads/.

S. 13
3.12 heatapp! App
The app is installed on mobile devices such as smartphones or tablets (iOS or Android) and is used to control heatapp! systems.
The app is currently available in German and English, Dutch, Italian, French, Turkish, Polish, German, Russian and Spanish. If the
tablet or smartphone is set to “English” the app is automatically displayed in English.
Language extensions in other languages will be made available via updates.
The heatapp! app is free and can be also be downloaded without a heatapp! system from the corresponding app stores. Demo
mode demonstrates operation of the heatapp! system.
3.13 heatapp! connect
Activate heatapp! connect using the setup wizard of heatapp! base if you want to be able to operate your heating system from
anywhere. heatapp! connect is a webserver and creates the connection when you access your heating while underway. heatapp!
connect does not save any data. All data, accesses and passwords are saved at home in your heatapp! base / base T2B and are
only accessible to authorised users after login. This concept offers maximum data security.
If you connect heatapp! base to the Internet in your home, then you can operate your heating with heatapp! and control the
room temperatures wherever your are. To do so, simply use your smartphone or tablet with a 3G/4G (UMTS/LTE) or Wi-Fi

4Technical Requirements
You can use the heatapp! system with your underfloor or radiator heating as well as with electric heaters, irrespective of what
sort of heat source you have. To be able to operate heatapp! conveniently from anywhere, you require:
•Your own residential Internet connection (broadband, cable, fibre optic, LTE)
•A wired or wireless home network (LAN, Wi-Fi) and
•A smartphone or tablet (from iOS 7.0 or Android 4.x from 8") with 3G/4G mobile (UMTS, LTE) and local wireless.
If you only want to use heatapp! at home and never underway, then all you need is a smartphone or tablet without even a
mobile phone connection.
The heatapp! app is currently available for iOS (iPhone, iPad and iPod from iOS 7.0) and Android (from version 4.x for tablets
from 8") and will soon be available for other operating systems and mobile devices.
You do not require any knowledge of heating technology because heatapp! is installed by experts for you.
4.1 Conditions and requirements
Fig.: 2 WLAN- and Z-Wave - Networks
The heatapp! system works with two different networks. heatapp! base and heatapp! gateway communicate with each other
via the home network. The radio components communicate via Z-Wave radio with the heatapp! gateway.
To operate a heatapp! system, an Ethernet network (LAN / WLAN) is required. In most applications this is provided through use
of an Internet connection and an appropriate router.
When connecting to the energy generator, you need a network connection in the boiler room. We recommend to connect the
heatapp! base via LAN cable with the router. Ensure that a network connection is available; if necessary via a switch or Powerline
Adapter.
heatapp! was developed in conjunction with the Institute for Internet Security. All data is stored centrally in your heatapp! base
in your home. To protect the system from unauthorised access, the heatapp! system can only be operated with a user name and
password. The access data is created during the installation. Ensure to keep your access data in a safe place, because without it,
your system is no longer operable. You can record the access data on page 134 at the end of this installation manual.

•Find a suitable installation location for the heatapp! base on a wall that fulfils the following requirements:
•A 230 V outlet must be available at the installation location of the heatapp! base.
•If the heatapp! base is going to be connected to the heat source (e.g. OpenTherm, 0-10V, demand contact) the
installation location must be close to the heat source.
•A LAN connection to the customer's home network must be available at the installation location of the heatapp!
base.
Or alternatively
•The installation location must be within range of the customer's Wi-Fi network so that the heatapp! Wi-Fi stick can
be used.
Note
In many boiler rooms, WLAN coverage is not possible. If a LAN connection cannot be established, you can switch to a Powerline
Adapter (DLAN). When selecting the Powerline Adapters, make sure that the sleep function is disabled.
Install the heatapp! base with the supplied installation material in the selected installation location.
5.2.3 Requirement request to the energy generator
There are different options to connect the demand request:
•T2B Bus: The T2B bus (THETA 2-wire bus) enables heatapp! to specify the hot water and flow temperature for all heating
circuits without room station.
Connect the T2B link cable to the terminals T2B BUS (in doing so, ensure correct polarity A / B!). Subsequently, use the the
set-up wizard and select the option “Regulator T2B” in the “Energy generator” field.
If the single room heat regulation is set to “OFF”, the heatapp! base T2B automatically displays a room group for each
heating circuit without a room station.
•OpenTherm: The OpenTherm protocol allows heatapp! to specify the hot water and flow temperature, provided the heat
source has an OT interface open to external connections. E.g. an OT room station can be replaced by the heatapp! base.
Connect the OpenTherm link cable to the terminals OT/BUS (in doing so, ensure correct polarity A / B!). Then subsequently
select the option "Heat source control system (OT/Bus)" in the field "Heat source" in the set-up wizard.
•Actuator signal 0-10 V: The heatapp! base converts the flow temperature specification or the heat source power into a 0-
10 V output signal. The parameter setting for this is performed in expert mode of the heatapp! base menu.
Connect the actuator signal input (0-10 V) of the heat source to the A2 / GND terminals and subsequently select the option
"Heat source actuator signal 0-10V (A2)" in the field "Heat source" in the set-up wizard.
Request contact (thermostat): For a demand (heating operation) from the rooms, the contact is closed. If there is no
demand from the rooms, the contact is opened. Connect the demand contact cable to the A1 terminal and subsequently
select the option "Heat source switching contact (A1)" in the field "Heat source" in the set-up wizard.
