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
