Variable Air Volume Controllers Description Design OPTIMA-RES-A is a compact system of supply and extract VAV controllers intended for ventilation control of residential premises. The basic functionality is continuous supply and extract air flow volume control in master/slave operation mode. Additionally, it can be switched into override operation modes like open or close damper, or minimum or maximum air flow volume control. The system of OPTIMA-RES-A system is encased in a galvanised steel box.
2 / 24 | Variable Air Volume Controllers Controls The residential VAV system is equipped with BLC4 type compact controllers in the master/slave connection. The controllers use analog input for the setpoint signal and analog output for the feedback signal. The type of the signals is DC 0 V ... 10 V. The VAV controllers are factory calibrated as standard to the air volume indicated in the table below or, upon request, they can be adjusted to site required settings of the Vmin /Vmax range.
Variable Air Volume Controllers Master (Supply Air) VAV Controller Setup Vmin adjustable between 0 and Vnom Vmax adjustable between Vmin and Vnom. Lowest possible adjustment is 20% of Vnom. Slave (Extract Air) VAV Controller Setup Vmin adjusted to 0, shall not be changed. Vmax adjusted equal Vnom, shall not be changed.

10 / 24 | Variable Air Volume Controllers Solutions for Room Controls with VAV Ventilation Systems The variable air flow controlled ventilation as a part of demand oriented control of room climate can be integrated in different ways according to various user requirements. The basic part of the climate control is the various room controllers. Each of them fits a different control solution at a corresponding cost level.
Variable Air Volume Controllers | 11 / 24 MZ3-Touch Ventilation Control Panel For VAV air flow control based on a single physical value like CO2 or VOC concentration. Functions The room controller can set the air flow volume on the VAV controller by the 0 V ... 10 V signal. The leading value for the control is the concentration of CO2 , eventually VOC in the air. For the measurement of this value, a separate transmitter shall be used with with a 0 V ... 10 V measurement signal.
