CONTROLLER FOR INSTALLATION TWO VALVES ST-408N I2 TECH

ST-408N Controller

is a multifunctional device designed to operate central heating installations. Thanks to the extensive software, the controller can perform a number of functions:

Functions performed by the controller:

• smooth control of two mixing valves
• DHW pump control
• Return temperature protection
• Weather control and weekly control
• independent analog output 0-10 VDC (e.g. for gas boiler control)
• two voltage-free outputs configurable
• two configurable voltage outputs
• Cooperation with three binary peace regulators
• cooperation with the room regulator with RS communication
• possibility of connecting the ST-65 GSM module
• possibility of connecting the ST-505 ETHERNET module
• possibility to control two additional valves using additional ST-61 v4 or ST-431n modules
• possibility of software update via USB port

Controller equipment:

• large, 4.3" color LCD touch screen
• DHW sensor
• external sensor
• valve temperature sensors
• return temperature and boiler temperature sensors
• housing made of high quality materials resistant to high and low temperatures

Dual valve support as standard
