Safety codes &regulations
THE DISPLAY MUST BE INSTALLED IN ACCORDANCE WITH LOCAL SAFETY CODES AND REGULATIONS.
PLEASE READ CAREFULLY THE MANUFACTURER’S INSTRUCTIONS BEFORE STARTING THIS DISPLAY.
Version concerned
The following manual is only valid for version higher or equal to 11.7 of LennoxHydrocontrol display. In case of Chiller connected to
the LennoxHydrocontrol the version of Chiller control must be higher than Ch60 v2r3.3 or eCH v0r2.2

TECHNICAL SPECIFICATIONS
Technical features
The HMI is a touch-sensitive screen LCD display. It is managing up to 32 FCU. This display can also be connected to 1 Chiller
which allows to managed the working mode changeover and the water temperature. The HMI is able to control up to 9 different
schedules.
Six languages are supported by the HMI
- English
- French
- Italian
- Spanish
- German
- Portuguese
The HMI uses 24Vac 50/60Hz power supply. In case of power failure the HMI will use its supercapacitor for internal memory.
2 entire days are necessary to fully charge the supercapacitor
The HMI is compatible with the LENNOX Chillers with a version higher than Ch60 v2r3.3 or eCH v0r2.2 and the FCU mounted with
the CTRL2303D4A-BDC controller. It can be used even if the FCU already have a connected thermostat.
Dimensions & weight
The following table indicates the dimensions and the weight of the HMI:
Device Height
(mm) Width (mm) Thickness (mm) Weight (g)
HMI 142 208 35 460
Compatibility
The HMI offers a web access via an Ethernet connection using a web browser.
The connection between HMI and FCU uses the MS/TP BACnet protocol.
The HMI can be connected to the FCU even if a thermostats is already connected.

INSTALLATION
Fastening
The HMI is a wall mounted display. To fasten the HMI on a wall we recommend to use the dedicated holes at the back of the
device.
There are two possibilities to fasten the HMI.
1. Partially build in the wall
Cut a hole into the surface
Mount the HMI using the 4 outside mounting holes
Opening the HMI
To access the wiring and fixing area you have to open the HMI on the top of the device and spin the screen. /!\ The display is
screwed to the black case.

Picture2: Hydrocontrol schematic (Partially build in wall)

-6-HYDROCTROL-IOM-1903-E
INSTALLATION
Wirings
Two different connections are necessary. But some other can be added in case of option
1. Power supply connection
The 24Vac 50/60 Hz power supply is required and has to be connected in the following pins: See picture index 1
2. BACnet MS/TP connection
Connect the BACnet MS/TP network to the dedicated pins. We recommend to use shielded twisted pair cable. The daisy-
chain connection is required. (star and ring connections are forbidden): See picture index 2
Chiller connection (Option)
In case the HMI is also connected to the Lennox chiller, The BACnet MS/TP communication card (S/n: (EL)4770643E) is
required on the controller of the chiller.
3. Ethernet connection (Option)
The HMI offers the possibility to be a web server. This means the display is also accessible via internet. You can connect
the HMI to your network using the RJ45 cable. See picture index 3
2. On a wall
Place the HMI on the wall and mark at least 4 points for screws and the hole for electrical wirings
Cut the hole for wiring and drill screw holes
Mount the HMI on the surface

INSTALLATION
Software installation
The HMI is supply without the HYDROCONTROL application loaded inside it.To load the application you must use one USB flash
drive with the both files (ask them to a LENNOX technician):
•Lennox Suite V11_7.PDB (You have to use at least the version 11.7)
•eTCH_V340_B-3935.FLS
Then insert the flash drive in one of the USB connectors of the HMI and power the display. The following display will appear:
Press “Oui”(yes) and the installation will start and the next screen will appear:
Wait the end of the installation
Once it is done please remove the flash drive and the HMI will restart automatically

Fan coil settings
To make the FCU communicating with the Hydrocontrol and working accordingly your requests you will have to set them with the
EC-Smart_Vue thermostat.
Connect the thermostat to the FCU controller using a RJ45 cable
To access all the parameters, from the home screen press the menu button for 5 seconds.
Use the arrows to set the password to 9995
You will then access the different setting menu. Use the button menu to choose the submenu you want to go and use one of both

Password management
Three main levels of password are managed by the application.
1) No connection: It is a visualisation level. The user has access only to functioning displays. The schedule and setting displays
are hidden.
2) User level: This is a operator level. The user has the access to schedule menus. He can change some set points, create the
schedule and add the FCU/chiller to the schedule zones.
3) Admin level: The user has the full access to the application. He can change the HMI settings and the application settings. This

2) Number of FCUs: Select the number of fan coil connected to the HMI
3) Changeover:
1) Chiller: the FCU changeovers are based on the chiller changeover
2) First FCU: the FCU changeovers are based on the changeover of the FCU which have the first address
3) Cooling: All the FCU are forced in cooling mode
4) Heating: All the FCU are forced in heating mode
4) Reset FCU config: Check this flag to reset the display of the FCU according to there configuration
5) Chiller installed: If the HMI is connected to one chiller then check this flag.
6) Language: The HMI language will also change according the selection
7) IP address / Subnet Mask / Gateway: You can set here the Ethernet connections
8) DHCP:By default the HMI is not set as DHCP. must be flag for DHCP connection
9) MS/TP: This flag must be always checked to have the BACnet MS/TP connection with the FCU and the chiller. The drop list at
the right of MS/TP flag is the MS/TP baud rate. By default the baud rate is 38400.
