EV91C - SLAVE
MODULE FOR
REGULATING TWO OR
OPERATION
The device uses a measuring probe to read the
temperature value of the delivery header and if the
temperature drops below a set value and for a xed
time, the device will switch on the rst auxiliary boiler
by opening the buttery valve and turning on the re-
levant burner.
If after a certain period of time one boiler is not enough,
the second one will be turned on, and so on.
When the number of turned on boilers becomes ex-
cessive, the control unit will turn them off by shutting
off rst the burner and then, after an adjustable delay,
the buttery valves.
CALCULATED BOILER TEMPERATURE
The boiler temperature calculated by the control unit
may be xed or sliding. When it is xed, the tempe-
rature value stays unvaried (i.e.: exactly like the set
value), whereas when it is sliding, the value set is
added to the highest temperature value required by
the connected slaves. It is thereby possible to regu-
late the boiler with a temperature that constantly va-
ries according to plant requirements.
N.B.: when setting the required boiler temperature
value, take into account that with the xed point regu-
lation this will be the value used by the control unit
whereas, with the sliding point regulation the value
set will represent the increase with respect to the
max. value established by the various control units
USE
The EV91C module is suitable to be used on all types
of heating plants where it is required to portion out
power over several cascaded boilers.
The module with address 0 enables full management
of two cascaded boilers by controlling automatically
both the buttery valves and the burners.
When more than two boilers are present, add as
many EV91C modules as necessary to cover sy-
stem requirements. The maximum number of EV91C
mo-dules that may be connected is four, for a total of
eight cascaded boilers.

of the plant.
LIMITS
The EV91C module also enables to set min. and
max. boiler temperature limits within which the cal-
culated temperature may vary. The control unit will
ensure that these values are not exceeded.
REGULATION
The device controls automatically both the burners
and the relevant buttery valves. The valve of the
main boiler is always open; when the auxiliary boiler
intervention is required the relevant valve and burner
will open in sequence.
The temperature value (that may be xed or sliding)
calculated by the control unit is used as max. boiler
temperature value. Should this value be exceeded,
all burners are turned off whereas the main boiler but-
tery valve stays open and the auxiliary boiler butter-
y valves are opened or closed as necessary.
When the measured temperature drops below Diff 1
value the main burner will switch on and it will switch
off as soon as the calculated boiler temperature (TCC
value) is exceeded.
If the temperature drops below Diff 2 value and stays
at this value for a certain period of time (to be set
on the control unit) then, an auxiliary boiler will be
switched on (in addition to other boilers operating
yet).
When a new boiler is switched on, the relevant but-
tery valve will open and after a certain time (to be set
on the control unit) the burner will turn on.
Auxiliary boilers are cut off (always one at a time),
when the measured temperature exceeds Diff 1 value
and stays at this value for a certain period of time.
DIFFERENTIAL 1
Main boiler differential: it indicates the temperature
difference, referred to the one calculated by the
control unit, below which the main boiler burner is
switched on.
DIFFERENTIAL 2
Auxiliary boiler differential: it indicates the tempera-
ture difference, always referred to the one calculated

by the control unit, below which an auxiliary boiler is
switched on.
BOILER ROTATION
To obtain even power consumption of the different
boilers, the main boiler is rotated automatically after a
set number of days.
The control unit at the set time will replace the main
boiler with the next one. Set “FIXED BOILERS” in the
conguration menu if this function is unnecessary.
MAIN CONTROL UNIT
The main control unit (or master) has address 20 (no
address bridge). The measuring probe shall always
be connected to this control unit.
This control unit implements all logic and regulation
functions and it is adequate for controlling automati-
cally two boilers (boiler no. 1 and boiler no. 2). The
master control unit determines the operation of all
auxiliary cascaded control units through the bus.
AUXILIARY CONTROL UNITS
Auxiliary control units are used when there are more
than two boilers. Their address determines the boil-
ers sequence according to the following logic:
Address 21: boilers 3 and 4
Address 22: boilers 5 and 6
Address 23: boilers 7 and 8
The chief thing is to give addresses in progressive
sequence without intermediate skipping. Since pro-
cessing is implemented by the master control unit no
measuring probe is to be connected to slaves.
