3.3 Version CONTROL EVO CAV

CONTROL EVO CAV: this control option is set to operate at constant air-flow, it is supplied complete with pressure transducer
and air temperature sensors installed on the fresh air intake and room return air.
The control system allows to select, in stepless mode, the supply and return fan speeds and automatically manages the heat
recovery by-pass damper through the motorized On/Off control.
It also manages the summer/winter seasonal change over and programming for daily time zones.
The control can also manage an optional hot water or cold water coil through a 3-way modulating valve and an additional
supply air sensor in order to maintain a fixed point operating logic.
The same logic can also be used to manage an electric post-heating coil, if present.
The system alerts to the user when filters need replacing (the clogged state of the filters is monitored by a pair of differential
pressure switches supplied as standard) or the onset of any alarm and this may also be integrated into modern home
automation systems via RS485 serial port with Modbus protocol.
