EHI-2

Features:

• Smooth control of a three or four-way mixing valve
• Control of the operation of an additional pump, with the ability to choose the type of device (heating pump, hot water pump, circulation pump, floor pump)
• Control of the operation of a low-voltage contactor, with the ability to choose the type of device (heating pump, hot water pump, circulation pump, floor pump, and alarm)
• Two built-in valve control modules
• Weather control of the valve
• Weekly control
• Protection of the return temperature
• Cooperation with a room thermostat with traditional (two-state) communication or equipped with RS communication
• Software update via USB.

The EHI-2 mixing valve module allows you to extend the Sinum system to support 2 mixing valves. The controller has voltage outputs to operate 2 mixing valves (open/close), 2 pumps dedicated to valves and 1 additional pump. In addition, it has a voltage-free contact and the ability to connect an RS regulator or two 2-state regulators. The device can also work independently without being connected to the Sinum control device. Communication with the Sinum EH-01 control device is done by wire via the TECH RS BUS.
