Zone controller

(VT.K500.0) The zone controller is designed for complex automation of the heating system in an individual house. The device allows remote heating control in rooms using VT.AC801.0 room thermostats, and control over pumping-mixing units based on thermostatic or rotary valves.

You can connect the following to one controller:
• up to 16 room thermostats;
• up to 18 two-position electrothermal drives with a supply voltage of 24 V;
• up to two drives included in the pumping-mixing unit with the possibility of smooth regulation according to a weather-dependent algorithm;
• up to two pumps included in the pumping-mixing unit;
• up to three analogue temperature sensors.

If necessary, digital temperature sensors can be additionally connected to the controller via a 1-wire bus.

Main functions and capabilities of the controller:
• support of data transmission via GSM and Wi-Fi;
• heating system remote control, setup and control via the VALTEC HEAT COMFORT mobile application and web interface;
• free configuration of the heating system to suit the needs of a specific facility;
• ability to load pre-configured heating system configurations into the device;
• control over direct and mixing heating circuits;
• zonal control of room temperature using VT.AC801 room thermostats with RS-485 communication interface;
• possibility of control over eight rooms with combined heating (for example, radiators and underfloor heating);
• support of up to 16 independent temperature zones (heating circuits) and two pumping-mixing units;
• possibility to connect up to 18 two-position electrothermal 24 V servo drives to the controller of normally closed or normally open version;
• smooth control of two-position electrothermal servo drives using a PWM power signal;
• possibility to control actuators in the discrete mode (via relay outputs): pumps, boilers, water heaters, rotary valve drive, etc.;
• possibility to connect wired analogue temperature sensors and additional digital sensors via a 1-wire bus;
• sensor calibration function;
• weather-dependent regulation of the heating medium temperature;
• possibility to select a standard weather-dependent algorithm schedule or its custom setting;
• possibility of individual setting of operating parameters for each heating circuit and each actuator;
• regulation of the heating medium temperature based on the air temperature in the room (based on the data from the room thermostat or an external temperature sensor);
• maintenance of the heating medium temperature at the given temperature setting;
• setting up heating system schedules and operating modes;
• automatic transfer of circuits to the summer mode and summer pump scrolling function;
• notifications in case of emergency situations;
• maintenance of connection with the device in case of pion (built-in power supply);
• possibility of control via a voice assistant (Alice).
