Product range update

The VALTEC automation range underwent changes: instead of VT.AC711 chronothermostat, VT.AC634 electronic indoor dual-circuit chronothermostat has been put on sale.

The main application area of the new product is combined heating systems, for example, those combining radiators and underfloor heating.

VT.AC634 chronothermostat has two relays, which let it possible to control two heating circuits. The device switches them on/off sequentially based on a signal from a temperature sensor (built-in or remote) and in accordance with the temperature difference preset during the setting.

The new model has a modern design with a large display, touch buttons and intuitive indication of circuit operation, as well as a number of features of construction compared to VT.AC711 thermostat (housing and mounting part, type of connection of the external sensor, etc.).

Temperature maintenance based on the readings of the built-in or remote sensor;
Daily programming of temperature conditions (6 modes per day);
Weekly programming of temperature conditions;
Frost protection according to the readings of any of the chronothermostat sensors;
Hysteresis setting (the difference between the thermostat relay contacts opening and closing temperatures);
Setting of the temperature drops (ΔT), at which one of the heating systems (for example, radiators) is turned off, but the second system (for example, underfloor heating) continues to work;
Calibration of the temperature sensor readings according to the control thermometer;
On-screen display of operating modes, time and temperature;
Selection of an operating temperature sensor;
Display backlight;
Adjustment of the display backlight brightness;
Customizable buttons sound;
Buttons lock for settings protection.

Chronothermostat structural features allow it to be used with both normally closed and normally open servos.

Power supply voltage of the device: 220 V (50 Hz).
