C2
Heating
Control Type
•H0.25
•H0.35
•H0.50
•H0.75
•Pi15
•Pi30
This setting controls how the heater, when
maintaining a set temperature, responds to
information from the thermostat.
H stands for Hysteresis. A hysteresis setting
means the radiator will respond when the
temperature goes above or below the set
temperature by a certain threshold. E.g. If you
select H0.25, it will respond when the
temperature is ±0.25 °C beyond the set
temperature.
Pi stands for PID Control, which in this context
means the radiator checks the temperature and
responds based on a time interval. E.g. Pi15
means the radiator will check the temperature
and respond every 15 minutes.
C3
Temperature
Measurement
Compensation
•- 3 to +3 ° C
(intervals of 0.1° C)
Adjust the baseline from which the radiator
reads the temperature. If it’s reading too low,
adjust to a minus number. If it’s reading too high,
adjust to a positive number.

2 – Control via App
To control your radiators via WiFi you need to purchase a WiFi hub. Commands from your app are
received via the router and then the hub sends them to your radiators via a radio frequency.
2A – Setting up the WiFi Hub
•Connect the hub to your router with the supplied ethernet cable.
•Plug the hub into the mains with the supplied USB cable and power adaptor.
2B – Setting up the App
•Download the Lucht LHZ Smartcontrol App
•Create an account.
•You will be sent an email to verify your account.
Click on the link and return to the app. Press Back
to go to the login screen.
Note – you can also control your
DSM radiators by PC. Just go to this
link and follow the same steps:
https://smartcontrol.lucht-
lhz.de/#/signIn

•Login to your account
•Set up your house on the app. Add a name and select the time zone.
•Connect the WiFi hub to the App. The easiest way to do this is by pressing the connection
button on the WiFi hub while this screen is showing.
•If this doesn’t work, the App will prompt you to add the WiFi hub manually by entering the
long code on the back of the WiFi hub.
2C – Connecting to your Radiators
•Press install heater Hold down on radiator for
three seconds. You should see the symbol
appear at the top of the screen.
•NOTE – the symbol may be hard to see if you are looking

name and other settings via the “More” menu when you
click into the radiator.

2D – Using the App
Home Screen
This is where you can manage all your radiators and make universal changes to your account.
NOTE – the Lucht LHZ is also designed to work with power meters, so you will see some functions that
don’t affect your radiators.
•To delete a radiator – select the radiator by checking the circle in
the corner and pressing delete .
•To toggle between At Home and Away mode – tap the house icon
at the top . When the radiator is set to Away mode, your radiators

can adjust this margin in the More -> Setup menu.
•To set up geolocation – press the menu button in the top right
corner and press Homes . Press your home and then press
Geolocation . From here you can set your location and radius. When
geolocation is enabled, your radiators will switch to Away mode when
your phone moves outside this radius.
•To invite new users – follow steps as above for Geolocation but
press Invite Users . Enter the email address of the new user. New
users will be able to access home and heating settings but will not be
able to invite other users.

•Use Man / Auto toggle to switch between manual and auto mode
•On Manual mode, you can use the tape measure, or the – and +
buttons, to adjust the temperature between 0 – 30 °C.
•You can also do this on Auto mode, where the new set temperature
will run for 90 minutes before it reverts to the schedule.
•You can adjust the programming by pressing More and then
Schedule .

Setting a Schedule

set temperature (i.e. 0.2 °C)
PID – radiator switches on/off by
checking set temperature after a
period of minutes (i.e. 15)

2E – Alexa
Use your voice to control your radiators via Amazon Alexa.
•First install the Heating Control skill on the Alexa app
