DESCRIPTION
The EU-M-7n control panel is intended for cooperation with the EU-L-7e
external controller. It enables the user to control the devices of the
underfloor heating system.
The EU-M-7n offers the possibility of activating/deactivating a zone, changing
the pre-set temperature in each zone and setting up schedules.
Functions offered by the controller:
- Communication with the EU-L-7e controller (via RS cable)
- Displaying settings: date and time
- Parental lock
- Alarm clock
- Screensaver – possibility of uploading photos, a slide show
- Software update via USB
- Managing the settings of the remaining zones – pre-set temperatures, schedules, names etc.
- Possibility of introducing changes in global schedules
Controller equipment:
- A glass panel
- A large, easy-to-read touch screen
- Flush-mountable
UWAGA
EU-M-7n Panel works only with main controller with software version above

CONTROLLER FUNCTIONS
1. BLOCK DIAGRAM – CONTROLLER MENU
2. ZONES
EU-M-7n is a master controller. it enables the user to edit most parameters
of other zones. In order to edit a given zone parameters, tap on the area of
the screen with he zone status information. The display shows the basic zone
editing screen:
- Return to the main menu
- Change the operation mode
- Operation mode of the controller – pre-set temperature according to the schedule. Tap here to open up schedule selection screen.
- Current time and date
- Enter the zone menu – tap on this icon to see further menu options: ON, Schedule settings, Temperature settings, Hysteresis, Calibration, Zone name and Zone icon.
- Pre-set zone temperature – tap here to adjust the value.
- Current operation mode
- Current zone temperature
2.1. SCHEDULE SETTINGS
The EU-M-7n control panel offers two types of schedules – local and global
(1-5).
- Local schedule is assigned only to the controlled zone. Any changes introduced in the local schedule apply only in this particular zone.
- Global schedules are available in all zones – in each zone only one such schedule may be activated. The global schedule settings apply automatically in all remaining zones where a given global schedule is active.
How to edit a schedule: After entering the schedule editing screen, the
schedule may be adjusted to the user’s needs. The settings may be configured
for two separate groups of days – the first group marked with orange colour,
the other one with grey colour.
It is possible to assign up to 3 time periods with separate temperature values
to each group. Outside these periods of time, a general pre-set temperature
will apply (its value may also be edited by the user).
- General pre-set temperature for the first group of days (orange colour – in the example above the colour is used to mark working days Monday-Friday). The temperature applies outside the time periods defined by the user.
- Time periods for the first group of days – the pre-set temperature and the time limits. Tapping on a given period opens up an editing screen.
- General pre-set temperature for the second group of days (grey colour – in the example above the colour is used to mark Saturday and Sunday).
- In order to add new periods, tap on „+”.
- Days of the week – orange days are assigned to the first group whereas grey days are assigned to the second one. In order to change the group, tap on a selected day.
The time period editing screen enables the user to adjust the pre-set temperature and the time limits of the period with the accuracy of 15 minutes. If the time periods overlap, they are marked with red colour. Such settings cannot be saved.
2.2. TEMPERATURE SETTINGS
This function enables the user to define the temperature outside the schedule.
The user may choose from comfort temperature, economical temperature and
holiday temperature.
2.3. HYSTERESIS
This function is used to define tolerance of the pre-set temperature in order
to prevent undesired oscillation in case of small temperature fluctuation
(within the range of 0 ÷ 5°C) with the accuracy of 0,1°C.
Example: when the pre-set temperature is 23⁰C and the hysteresis is set
at 0,5⁰C, the zone temperature is considered too low when the room temperature
drops to 22,5⁰C.
2.4. CALIBRATION
Room sensor calibration should be performed while mounting or after the
controller has been used for a long time, if the external temperature
displayed differs from the actual temperature. Calibration setting range is
from -10°C to +10°C with the accuracy of 0,1°C.
2.5. ZONE NAME
This function enables the user to assign name to a given zone.
2.6. ZONE ICON
This function enables the user to select an icon which will be displayed next
to the zone name.
3. TIME SETTINGS

displayed on the main screen (if auto time has been selected in the EU-L-7e
controller and it is connected to the Internet via a WiFi module, the EU-M-7n
panel will display current time automatically).
