Description
The automatic dT100 control for ventilation and temperature tasks was developed for flexible use in wineries. The OFF – MANUAL – NIGHT AIR – TIME operating modes can be freely selected using buttons in the front of the controller. The system directly actuates motorised closure flaps and fans. A programmed time regime ensures that the closure flap is always opened before the fan starts up. Deactivation is achieved in reverse order. The closure flap only closes with a time delay after the fan stops. In the TIME operating mode, ventilation in the case of an activated time window is controlled without regard for the indoor and outdoor temperature (e.g. for regular air renewal, tartaric stabilisation, etc.). In addition, a clock signal with defined activation and deactivation times can be defined in TIME operating mode within the time window. In the NIGHT AIR operating mode, ventilation is actuated in the programmed time window (up to 4 time windows) if the outside temperature is at least 1 °C (configurable value) lower at the starting point than the indoor temperature.
