6.7 COP constant pressure mode
6.7.1 Description
In constant pressure operation, the controller regulates the speed of the plenum to achieve the pressure
setpoint. If the PTHV-A display is present on the unit, it will show the pressure in Pa.
The pressure setpoint can be set by the potentiometer integrated in the controller, by an external poten-
tiometer CVF type with ON/OFF, by an external 0-10V source or by GTC ModBus.
6.7.2 Control wiring
For Analog/Digital controls use cable with the following characteristics:
• Sheath Ø: 6mm to 12mm
• Strand cross-section: 0.7mm² to 1mm².
• Recommended minimum stripping: 10mm
• Maximum recommended length: 30m
For Modbus control use cable with the following characteristics:
• Sheath Ø: 6mm to 12mm
• Strand cross-section: 0.7mm² to 1mm².
• Recommended minimum stripping: 10mm
For more information on Modbus communication see § "6.2 Modbus connection - Connection to a BMS",
