OPERATION
System description
6| EASYTRON Connect www.stiebel-eltron.com
The EASYTRONConnect system is designed for individual room
control of heating systems in buildings. The system can be con-
nected to a heat pump via ISGweb or operated independently.
Connecting the system to a heat pump enables demand-depend-
ent individual room control. Operation can be via the EASYTRON
Connect app.
If the system has an integral heat pump, the following functions
are possible:
- The system can optimise heat pump heating curves for the
connected heating circuits.
- The system can open all heating circuits for heat pump
defrost.
- The system enables the identification of rooms to be cooled
by the heat pump.
The system can be used for heating systems with wall mounted
radiators or underfloor heating.
The system can control 24 rooms. In each room, max. four ac-
tuators for radiators or channels for underfloor heating can be
controlled.
In conjunction with a control unit for underfloor heating, one room
temperature sensor is required per room.
The following components can be integrated into the system:
EASYTRON Connect base station EZE
The device is the central control unit and communication interface
for the system, which receives and transmits information from
and to other wireless components. The device is connected to the
wireless components via radio (Z-Wave).
Communication with the heat pump (optional) takes place via the
ISGweb (Internet Service Gateway).
EASYTRON Connect underfloor heating controller EHF
The device controls the underfloor heating system. The device can
be used to control eight channels in each case with up to three
thermoelectric actuators (EFS, not part of standard delivery).
The device contains an integral repeater to improve the wireless
range. The separate antenna can be routed out of the device to
improve the wireless connection.
EASYTRON Connect room temperature sensor ERT
The device captures the actual room temperature in rooms with
underfloor heating.
EASYTRON Connect radiator actuator ERS
Radiators can be controlled wirelessly with the device.
The actuators fit all commercially available valves with
M30x1.5mm connection or RA adaptor. Suitable adaptors are

www.stiebel-eltron.com EASYTRON Connect | 7
OPERATION
EASYTRON Connect app
available for heating valves with RAV and RAVL connections. Other
adaptors are available from specialist trade shops.
EASYTRON Connect repeater ERE
This device improves the wireless range.
EASYTRON installation stick EIW (WLAN) and EASYTRON
Connect installation kit EIL (LAN)
These products are used to help set up the system. Dial-up to the
client network is not required.
EASYTRON Connect app
The app enables the system to be operated via mobile devices.
Server connection
When the server connection is activated and the system is con-
nected to the internet, the system can be operated when away
from home via the EASYTRON Connect app.
Z-Wave wireless system
The Z-Wave wireless system is a wireless communication standard
especially for use in the smart home sector. Z-Wave uses two-
way communication with return acknowledgement. Only acknowl-
edged telegrams are considered to have been sent successfully.
In the case of communication faults, the send process is repeated
up to three times.
Any network operated device can forward the telegrams to other
devices on its own network. This creates an intermeshed network,
which is controlled by the base station. The base station refreshes
the routes when the network changes.
4. EASYTRON Connect app
The system can be operated via an app on mobile devices.
 Install the app on your mobile device.
 Ensure that your mobile device is on the same network as the
system.
4.1 User roles
The app can be used for user administration of several users with
different user roles.
User
Users have limited access rights to the setting options on the sys-
tem. Users can control rooms for which they have authorisation.
Admin
Admin has access to all system setting options. Admin can manage
all rooms. In the "Pro" section, Admin has limited access rights.

OPERATION
EASYTRON Connect app
8| EASYTRON Connect www.stiebel-eltron.com
Expert
Aside from the same rights as Admin, the Expert also has full
access to the setting options in the "Pro" section.
4.2 Operating modes
The heat pump is operated as standard with the system in PRO-
GRAMMED MODE (AUTOMATIC MODE).
You can use the app to influence the heat pump operating mode
if the selected action changes the operating mode.
Note
If the heat pump is in EMERGENCY MODE or MANUAL
MODE, the app cannot be used to influence the operating
mode. These operating modes are displayed in the app
as faults for operation of the base station.
Standby/ STANDBY MODE
You can switch the rooms individually to standby. Heating oper-
ation is no longer carried out.
If all rooms are switched to standby and no frost protection is re-
quired for the rooms, the heat pump switches to STANDBY MODE.
Note
In STANDBY MODE, DHW heating is not available.
The heat pump's frost protection function is activated.
If the frost protection function is activated for a room, the heat
pump switches to PROGRAMMED MODE (AUTOMATIC MODE). The
heat pump heats the room before the room cools down.
ECO action
If you are leaving the house for a specific length of time, you can
use the ECO action to lower the set room value to the selected
ECO temperature (night temperature). Once the selected time has
expired, demand returns to the comfort or ECO temperature (day
or night temperature) depending on the switching time.
Holiday action
If you are leaving the house for an extended period, you can use
the Holiday action to lower the set room value to the frost pro-
tection temperature.
If the Holiday action is selected for all rooms, the heat pump
switches to STANDBY MODE.
Note
In STANDBY MODE, DHW heating is not available.
The heat pump's frost protection function is activated.

www.stiebel-eltron.com EASYTRON Connect | 9
OPERATION
EASYTRON Connect app
After the extended period away from home, standby mode is
switched off again and the heat pump switches to PROGRAMMED
MODE (AUTOMATIC MODE).
Party action
Use the Party action to extend the period during which the heat
pump provides room heating to comfort temperature (day tem-
perature). Normal switching times are suspended for the selected
period. Once the selected time has expired, demand returns to the
comfort or ECO temperature (day or night temperature) depending
on the switching time.
4.3 DHW heating
You cannot make the settings for DHW heating via EASYTRON
Connect.
 Adjust the settings for the DHW PROGRAM at the heat pump
programming unit. For this, observe the operating and in-
stallation instructions for the heat pump and the instructions
for the WPM heat pump manager.
4.4 Retrofitting wireless components
WARNING Electrocution
 Devices should be installed by a qualified contrac-
tor.
Note
Battery-powered wireless components must be connect-
ed to the base station before installation.
 Pair the wireless components within a maximum
radius of 2 to 3m around the base station.
You can install additional components on the app or a computer
via the base station.
Retrofitting via the app
 Log into the app as "Admin" or "Expert".
 Go to the "Settings" menu.
 Go to the base station menu.
 Log in with credentials.
 Go to the "Wireless components" menu.
 Follow the app instructions.
Retrofitting via the base station
 Observe chapter "Installation / Connecting wireless
components".
