CONTROLLER FOR OPENTHERM I-2 PLUS TECH INSTALLATION

• The controller is designed to operate 2 actuators of mixing valves.
• It has a high-resolution LCD display on which all installation parameters are shown.
• Possibility to connect 2 heat sources
• The possibility of controlling an additional device, e.g. additional pumps on circuits without valves, lighting or a lawn sprinkler, etc.
• OpenTherm Communication

The i-2 PLUS controller is equipped with an OpenTherm communication connector.

Through its communication, the controller can change the set temperature of the heating device, change the DHW temperature, read the current operating parameters or signal alarm states.

The controller works in the OpenTherm+ ver.4.0 standard.

Functions performed by the controller:

• smooth control of two mixing valves
• possibility to control the parameters of the heating device thanks to OpenTherm communication (compatibility up to version 4.0)
• DHW pump control
• Return temperature protection
• Weather control and weekly control
• two outputs 0-10V
• two voltage-free outputs configurable
• two configurable voltage outputs
• boiler cascade control (binary signals)
• Cooperation with three binary peace regulators
• cooperation with 3 room regulators with RI-1 communication
• cooperation with the room regulator with RS communication
• possibility of connecting the ST-505 module or WIFI RS - management via eModule
• Possibility to control two additional valves with additional modules I-1M or I-1
• possibility of software update via USB port
