DESCRIPTION
General features0
EV90 remote controller is used in particularly complex systems where several different devices are required to solve heat regulation problems.
The system consists of a master device EV90, and one or more slave devices connected to the master through a communication bus called – FANBUS.
- Alphanumeric display and configuration keys. All commands and functions are selected by means of menu and adjustable via
two keys (+ and -). - All parameters values are displayed on a 4-line alphanumeric display with 16 characters per line. Two other keys are used to
pass from a parameter to another and to scroll through the configuration menu. - The date and the time, including summer/winter time changing, can be set directly on the MASTER EV90 front and used by all
devices connected to the FANBUS. - Transparent protection cover.
- Digital clock with charge reserve of 5 years.
- Boiler regulation (with 1 or 2 stages) maintaining a high enough boiler temperature in order to provide all connected users with
heat.
Electric features- Power supply: 230Vca 50Hz.
- Consumption: 5 VA.
- 2 output relays, contacts rating 5A- 250Vca (resistive load).
- 3 analog inputs: 1 to measure the external temperature, 1 to measure the delivery temperature, 1 to measure the return temperature.
- 1 RS232 communication channel for connection to a modem or directly to a computer.
- 1 communication bus FANBUS for SLAVE management.
- Alphanumeric display and configuration keys. All commands and functions are selected by means of menu and adjustable via

HOMOLOGATION AND INSTALLATION
Homologation
- Complies with the law 373, law n.10 dated 9 of January 1991 and D.P.R.412 dated 26 of August 1993.
- Complies with EN 60730-2-9; EN 60730-2-7 standards.
- ErP classification: ErP Class II; 2% (EU Reg. 811/2013 – 813/2013)
Installation and use- Control unit with fast coupling to the base with Faston connections. Application possibilities: wall, rear panel and flush
mounting.
- The EV90 control unit is used in particularly complex plants where several different devices are required to meet heat regulation requirements.
- The system features a master device (EV90) and one or more slave modules (EV91A-EV91B-EV91C-EV91D-EV92) connected to the master through a communication Bus called FANBUS.
- The device operates as a central control unit. Through its display and keyboard the user may display and modify parameters of slave control units connected to the FANBUS. A probe detects the value of the external temperature which is sent by means of the FANBUS to all relevant control units thereby avoiding duplication.
- The hour and date, including standard time, may be set directly on the front of the device and used by all devices connected to the BUS. Just one GSM modem lets you remotely manage and modify the parameters of the Master EV90 and all other control units.
- When an alarm is triggered by a slave, it is first transmitted to the master EV90 and then to a remote station or to an enabled mobile phone. Another function of EV90 is boiler regulation (with 1 or 2 stages); it maintains a high enough boiler temperature to provide all connected users with heat.
- Besides performing the function as the master of a system, the EV90 may be used as the control unit of a boiler with either fixed temperature or sliding temperature, by directly commanding a one- or two-stage burner.
