5. OPERATION WITHOUT PROSYS ECOWATT CONSOLE

Roof fans CTB, CRHB, CRVB ECOWATT are ready to work on constant pressure mode (COP/PI PRESSURE) with a differential
pressure reading taken on inlet side and a predefi ned set point from factory (100Pa).

6. OPERATION WITH PROSYS ECOWATT ACCESSORY CONSOLE

Acquiring the PROSYS ECOWATT console offered as an optional accessory, you will have access to the following operation
modes:
• Constant pressure system ( PI PRESSURE/COP ) with modifi able set point parameters.
• Constant airfl ow system ( PI VOLUME/CAV ) with modifi able set point parameters.
• Variable airfl ow system ( PROPORTIONAL/VAV ) (it is necessary to install an external sensor with an output analog signal
0-10V or 4-20mA).
• MIN/MAX operating system (it is necessary to install an external sensor with an output digital signal, time clock or external
relay).

6.1. INSTALLATION

It is possible to install a single PROSYS ECOWATT console linked with one CTB/CRHB/CRVB ECOWATT, or make a Modbus
communication network linking more than one unit with one PROSYS ECOWATT console.
