ECHO is a signal repeater which can be connected to the ID 985 LX /E and

ID 985/S/E/CK controllers.

Through the configuration of the parameter ErO it is possible to select 4 different types of visualization:

• exact reply of the current visualization of the device which ECHO is connected to
• visualization of the temperature value read by probe 1 (thermostat)
• visualization of the temperature value read by probe 2 (evaporator)
• visualization of the temperature value read by probe 3 (display or 2nd evaporator)
• visualization of Set Point

ECHO is connected to ID 985 LX /E or ID 985/S/E/CK through three wires,

which are also used to power supply ECHO.

The instrument is available in the 48x28,6 mm format, for panel mount.
