Cop Control (Constant Pressure) - S&P UVF ECOWATT Série Manuel D'instructions

8.4. COP CONTROL (CONSTANT PRESSURE)

This type of regulation is associated to multi-zone ventilation systems in which ventilation multi-
room is carried out by a single UVF-ECOWATT. Flow regulation per zone is done using motorized
dampers, so speed regulation of the fans aims to maintain a constant pressure in the ductwork. The
value of this pressure must be determined by experimenting during the system start-up process.
UVF-ECOWATT units are equipped with EC motors. The motors have specifi c terminals to receive a
regulation signal to control fan speed (0-10V).
The 0V signal corresponds to the fan stop, while the signal of 10V corresponds to fan maximum
speed.
To perform the speed regulation in COP mode, it is necessary to use the accessory CONTROL AE-
ROREG and the external pressure sensor TDP-D. In the CONTROL AERO-REG instruction booklet
it is contained the necessary information to carry on the electrical connection of the different com-
ponents.
1º Connect the pressure transmitter TDP-D (accessory) to the duct system where the ventilation
box is ducted. Ensure that pressure taps "+" and "-" coincide with those of the ventilation box:
