Central heating controller ST-409n

Advanced control of a central heating system. Central heating device control system with colour touch screen display.

Central heating system controller ST-409n working principle depends on mixing hot water supply circuit with return water to obtain the desired temperature setpoint and he maintained in a continuous line. Connected to each heating circuit mixing valve pump helps to distribute water temperature evenly.

The pump should be installed after of the mixing valve and the sensor behind the mixing valve and the precise temperature readings to get at the valve outlet.

Functions that are performed by the heating control

• Supporting up to three mixing valves
• Smooth control of three mixing valves
• Domestic hot water pump control
• Securing the return temperature
• Weather control mode (central heating operation with weather into account)
• Weekly work schedule
• Two configurable isolated outputs (. Eg bistable closed / opened)
• A configurable voltage output
• Cooperation with three Room temperature controller with traditional bistable wired communication
• Two RS connections
• Cooperation with a RS room thermostat controller
• Ability to connect a ST-65 GSM controller module
• Ability to connect a control unit ST-500 ETHERNET controller module
• Ability to connect additional mixing valve modules with additional ST-61 modules
