During winter, it adjusts the steam humidifier delivery. The humidity probe on the return line controls humidity. The hot and cold valve control is in automatic sequence, with central dead band to prevent instability.ĭelivery summer temperature compensation in relation to the outdoor one The S/W selector also lets you exclude antifreeze protection while the coil is powered by cold water. In case of the mixed coil, the season must be selected from the control panel or the remote selector. The cleanliness and healthiness of the filters is constantly monitored by the differential pressure switch as required by the relevant EU regulation The TAG antifreeze thermostat protects the coil from frost (in case of intervention) when the outdoor air damper closes and the unit stops The ambient temperature control is faster and more accurate, and the gap on the ambient set-point is smaller than that achieved with separate ambient/return temperature adjustment. The air delivery temperature varies according to the difference between the actual ambient temperature and that prescribed. This function allows the performance of a control loop with a high degree of difficulty to be improved, thereby reducing the delay with which the ambient/return probe indicates the interference that occurs in delivery and is used as a base when the ambient temperature is to be set. "Sliding" adjustment of the delivery temperature according to the ambient set-point (all air)ĭepending on the difference between the ambient temperature and the set-point, established at settable authority level, the delivery set-point is re-calibrated. The Tm fixed point probe controls the delivery temperature using the modulating actuator of the control valve.
