EV91B - SLAVE

SANITARY WATER

TEMPERATURE

REGULATION MODULE

OPERATION

The EV91B module works properly only when it is

connected through a two-wire serial bus (FANBUS)

to a Master device called MASTER EV90, otherwise

it will not work. The EV91B is an electronic device

designed for regulating the opening and closing of a

mixing valve according to the temperature required

and to the temperature read.

Regulation is carried out by a control unit of the

proportional-integrator type featuring proportional/in-

tegration constants that can be modied by the user

according to the type of plant and user’s habits.

The comparison between the water delivery tempera-

ture and the required reference temperature pinpoints

an error that denes the valve position on the basis

of the proportional band and the integration time. This

position is expressed in percentage: 0% indicates

that the valve has to move to fully close position and,

100% indicates that the valve has to move to fully

open position. The time the valve takes for passing

from full close to full open position is equal to the time

specied on the valve rating plate.

CIRCULATION PUMP

The circulation pump is switched on when the pro-

gram selected is “Always ON” or “Automatic” and

when within the programmed period.

USE

The EV91B module is suitable to be used on all types

of centralised sanitary water regulation plants.

This module is mainly used for regulating the tem-

perature of sanitary water, however it may also be

used for regulating generic temperatures of rooms,

greenhouses, swimming-pools, etc...

The EV91B is provided with a special program for

thermal sterilization of the system to prevent the risk

of Legionellosis (legionnaires’ disease).
