The ventilation and recuperation units are supplied with their own devices, which are, however, often very cumbersome to adjust and cannot be integrated in the building control system. Therefore, it is better to implement the control of the recuperative or air ventilation units directly by the Foxtrot system, which is fitted with a number of input-output modules suitable for this purpose. Gradually the library of function blocks is expanding, and they are ready for regulation of ventilation and recuperation units, fan coil units, etc. The advantage of this solution is in the flexibility of hardware, because the ventilation control itself can be combined with other technologies - both in software control, and hardware configuration of the control system.

 

Possible variants of the peripheral modules according to technology:

 

Fans:

discreet speed control of 230 V motor revolutions

relay modules,
e.g. C-HM-0308M

Continuous regulation of 230 V asynchronous motors, built-in version

C-FC-0230X

Continuous regulation of 24 VDC EC motors, a built-in version

C-FC-0024X

Continuous regulation of 24 VDC EC motors , 0÷10 V control

E.g. C-HM-0308M

Continuous regulation of motors with a frequency changer, 0÷10 V control

E.g. C-HM-0308M

 

Sensors:

Temperature sensors – the type of sensors according to the selected module

E.g. C-HM-0308M

Condensation sensors

C-HM-xxxxM

Indoor CO2 sensors

C-AQ-0001R

 

Servo-drives:

Servo-drive with 3-point control, 230 V or 24 V

relay modules,
e.g. C-HM-0308M

Servo-drive with 0÷10 V analogue control

AOUT,
e.g. C-HM-0308M

Damper actuator, 1-point control

relay modules,
e.g. C-HM-0308M

Servo-drive with the MP-Bus protocol

UC-1203

 

Further it is possible to control electrical heating (16 A relay outputs, e.g. the C-OR-0008M), to scan inputs from defective sensors (filter, etc.), from remote control (manual control e.g. from the bathroom, etc.).
