ROOM CONTROLLERS WITH AUTOMATIC SPEED AND ECONOMY FUNCTION
DB-TA-3D3-00A
FUNCTION The water sensor can be used as automatic changeover in 2pipe systems or as minimum thermostat for 4- pipe systems. For 2- pipe systems the working season can be selected by sensing the temperature of water delivered to the fan at the inlet of the valve.
With electric heater operating mode: - summer: it is possible to heat when temperature decreases from setpoint of neutral zone value (spring or autumn or offices with different thermical load); - winter: it is possible to have a second heating stage.
2- pipe systems: automatic changeover selection
2- pipe systems: heating with electric heater
2- pipe systems: heating without electric heater
2- pipe systems: cooling and heating with electric heater
2- pipe systems: cooling without electric heater
4- pipe systems: operating mode For 4- pipe systems the season is selected according to room temperature and setpoint with a neutral zone selectable.
FUNZIONE ECONOMY The economy function can be inserted manually by parameter or with an external contact when the water sensor is not used for automatic changeover for 2- pipe systems or is not used as minimum thermostat for 4- pipe systems. For 2- pipe systems the working setpoint is the heating or cooling economy setpoint according to the working season. For 4- pipe systems the activation points for heating and cooling move away in order to heat and cool less.
