Demand based air curtain control

The air velocity of the air curtain is automatically optimised based on the measurements of the HVAC sensor. The air curtain operates completely automatically in function of the measured temperature(s), humidity, CO2, air quality, etc. These automatic air curtain control solutions guarantee the comfort of the occupants in a discrete way. Significant energy savings can be realised.

Title and description

FS-D-000013

AC motor 2,5 A | Temperature humidity control | 5 steps

Temperature humidity control for AC fans with single-phase motor. The maximum motor current is 2,5 A. The fan speed is controlled in function of relative humidity. The RTVS8 transformer fan speed controller regulates the motor speed in steps. Fan speed can be regulated from high to low or from low to high. The HVAC transmitter receives 24 VDC supply voltage via the RTVS8 controller. All settings can be adjusted via Modbus RTU. With this solution, it is also possible to control fan speed in function of temperature. If the motor is equipped with thermal contacts (TK), RTVS8 can detect motor overheating in an early stage and disable the motor to prevent damage.
