SPECIFICATIONS
The Highcross ECM-UTM4D is an electronic universal 3-channel
thermostat module designed to control of heating or cooling sys-
tems.
The module has three built-in thermostats, three power relays,
four analog inputs for temperature sensors, three pairs of digital
inputs for priority dry-contact control from window-contact or etc.
All relay outputs are normally open and are disconnected when
the power is off.
The control, data exchange and conguration are all handled via
TCP/IP protocol.
The module is designed to be installed on a standard 35 mm DIN
rail.

LED “status” indicates the power connection
and connection status with controllers
Off No power connected
Blink
(1 Hz) No connection with external controllers
Fast blink
(4 Hz) The device is in bootloader mode
On Connected to external controllers
LED “link“ indicates Ethernet network
link and activity
Off No connection to Ethernet network
Blink Connected to Ethernet network
Receiving Ethernet data packets
On Connected to Ethernet network
No network activity
LEDs “outputs 1…3 on“ display status
of relay outputs
Off Relay is open
On Relay is close
LEDs “outputs 1…3 auto“ display that
built-in thermostat control of relay output
Off Output is not controlled by internal setpoint
On Output is controlled by built-in thermostat
Multifunctional button “reset“
To reboot the device push the button for 1 second
To reset the device to factory defaults push and hold the
button for 5 seconds.
IP–address will be set to 10.0.1.101, subnet mask - to
255.255.255.0. All other settings will be set to default values
For rmware update, power off the device, push and hold
the button and power the device on. Release the button after
the LED “status” will start to blink fast.
The network settings of the device started in bootloader
mode are: IP–address – 10.0.1.101, subnet mask –
255.255.255.0
The PWR “+” and “–” terminals are designed to power the device
+12…48 VDC if connected Ethernet switch has no PoE support.
Terminals of relays 1…3 (pairs of K1A-K1B, …, K3A-K3B) are con-
tacts of normally-open relays. Relays can be controlled either by
built-in thermostats or by external controllers.
Terminals of sensors 1…4 are designed to connect supported
analog sensors. Sensors 1…3 can be used by built-in thermostats
1…3 as well as by external controllers. Sensor 4 can be used by
external controllers only.
Terminals of digital inputs 1A, 1B,…,3B are designed to priority
dry-contact external control of relay outputs. For example, win-
dow-contact to force off heating while window is opened.
SETUP AND CONFIGURATION
The conguration of the module is handled via web-interface.
To start working with the device:
• Connect the device to the Ethernet switch. If the switch has
no PoE support, connect the power +12…48 VDC to the PWR
terminal
• Ensure that your computer can connect to the network address
10.0.1.101 or set the TCP/IP settings of active network adap-
tor to: IP address –
10.0.1.100 , subnet mask – 255.255.255.0
• Enter 10.0.1.101 in address bar of your web-browser
• Enter: login – root, password – root
• Congure the device settings
The web-interface contains the next web-pages:
Home Displays the hardware revision and the
rmware version
Settings
Network settings, type of data exchange
protocol, analog input settings, thermostat set-
tings, external control settings
Control
Displays current temperatures and measured
values of analog inputs, thermostat’s
setpoints, state of priority inputs.
