The following is provide for your guidance
only, and assumes the ventilation air is
taken directly from outside. The sizes of the
vents may need to be increased in respect
of other appliances installed in the same
area, and seasonal use. Take care that the
position of low level vents would not subject
to adverse weather conditions, ie flooding.

2.2.2 Outdoors
“MURELLE EQUIPE 100-150 BOX ErP”
heat modules can also be installed out-
doors with the specific exhaust for single
module code 8089530.
2.3 SYSTEM REQUIREMENTS
The heating system should be flushed prior
to the connection of the heating modules.
The system should be treated in accord-
ance with BS 7593. Sime Ltd recommend
only the use of Fernox products for the
flushing and final treatment of the system
water. This is particularly important in hard
water areas.
It is recommended that the inhibitor con-
centration is checked at installation, system
modification and at every service in accord-
ance with the manufacturers instructions.
Test kits are available from inhibitor stockist.
WARNING: Failure to clean the heat sys-
tem or add an adequate inhibitor invali-
dates the device’s warranty.
Gas connections must be made in accord-
ance with current standards and regula-
tions.
When dimensioning gas pipes from the
meter to the module, both capacity volume
(consumption) in m3/h and gas density
must be taken into account.
System pipe sections must be able to guar-
antee sufficient supply to cover maximum
demand, limiting pressure loss between the
meter and any utility device no greater than
1.0 mbar for second family gas (natural
gas).
A sticker inside the module includes iden-
tification and gas type data specific to the
module.
2.3.1 Condensation
drain connection
The condensate drain must be connected
to the civil drain by a pipe with minimum 5
mm per meter gradient for condensation
collection.
Only stainless steel or plastic pipes are
suitable to convey condensate.
2.3.2 Filter on the
gas pipe
The gas valve on each generator is supplied
ex factory with an inlet filter, which, however,
is not adequate to entrap all the impurities in
the gas or in gas main pipes.
To prevent malfunctioning of the valve, or
in certain cases even to cut out the safety
device with which the valve is equipped,
install an adequate filter on the gas pipe.
2.5 FILLING THE SYSTEM
Cold system filling pressure must be 1 bar.
The system must be filled slowly so that air
bubbles are released through the specific
escapes.

WARNING: In models “100-150 BOX ErP”
the tubes connecting hydraulic separator
kit can be inserted in a specific protective
box code 8101517 supplied separately
(see fig 4).
2.9 RS-485 BOARD (fig. 8)
Each generator is supplied with the RS-
485 board which allows you to manage the
boilers in sequence/cascade (see fig 8).
2.9.1 MODBUS mode (fig. 8/a)
This mode allows for MODBUS communica-
tion of at least two boilers in cascade and is
performed by requesting another RS-485
board provided in the kit code 8092244.
ATTENTION: Communication will occur
only with the MASTER generator, (gen-
erator with PAR 15 = 0), interpreting
the cascade as a single heat capacity
generator:
P CASCADE = P GENERATOR x No. GENERATORS.
To install the second board, proceed as
follows:
- Remove the cover and electrically con-
nect the second RS-485 board equipped
with lid to the RS-485 board already
installed in the MASTER boiler (boiler with
PAR 15 = 0) with the wired connector
provided in the kit.
CAUTION: Insert the wired connector
with caution.
- Set the DIP SWITCH of the new board in
MODBUS mode.
- Close the lid of the second board.
- Choose the communication configuration
suited to the MODBUS network (PAR 17
INST) according to Table PAR 17 INST.

CONNECTIONS
Each module is supplied with a power cord
which, if replacement is required, it must
be replaced with one of similar type and
dimensions.
230V – 50 Hz single phase voltage is
required using a fuse protected main switch
with at least 3 mm. between contacts.
Observe the L – N polarity and ground-
ing connection. Each generator should be
fused at 3 A.
NOTE: Sime declines all responsibility for
injury or damage to persons, animals or
property resulting from the failure to pro-
vide for proper earthing of the appliance.

The RS-485 board for management in sequence/cascade is
placed at the rear of the control panel of each individual gen-
erator as shown in the figure.
CONFIGURATION OF CASCADE PARAMETERS
Sequence/cascade installations must have the following INST
parameter set on all connected generators:
PAR 15 = 0 for the first generator (MASTER)
1 .... 7 for the other generators (SLAVE)
(Avoid assigning the same number to SLAVE
generators)
Set the following INST parameter if polypropylene smoke
collectors with a clapet valve are used in sequence/cascade
installations:
PAR 1 = 6 (for NATURAL GAS generators)
14 (for PROPANE generators)
To access the INST parameters, see point 3.3.
In addition, when the number of connected generators in cas-
cade is more than two, parameter OEM A1 of the MASTER
generator must be configured as well.
To access the OEM parameters press simultaneously the but-
tons (

2.11.3 Room Thermostat and/or Timer
(clean contact)
The heating demand can be controlled by a
thermostat and/or timer (TA) connected to
CN6 terminals 7-8 (see fig 11), after having
removed the existing bridge. The control
being used must be of a class conforming
to the standard EN 607301 (clean electri-
cal contact).
2.11.4 Remote control SIME HOME con-
nection (optional)
The heating demand can be controlled by
use of remote control unit SIME HOME
(code 8092280/81)
The remote control unit allows for complete
control, except lockout reset.
The generator will display CR.
For installation and use of the control follow
the instructions in the package.
NOTE, Ensure PAR 10 set to 1 (PAR 10 = 1)
2.11.5 External Sensor (8094101)
An external sensor (code 8091401) can
be connected, which can automatically
regulate the flow temperature value of the
cascade delivery according to the external
temperature.
For installation follow the instructions in the
package. It is possible to make corrections
to the values by adjustment of PAR 11.
2.11.6 Heat Demand by 230v
The heat demand can be controlled by 230v
applied to terminal 14 of CN7, and removal
of the bridge on CN6 terminals 7 & 8.
2.11.7 BMS (Building Management Sys-
tems)
The cascade of generators can be control-
led by a BMS signal, and should be con-
nected as shown in fig 11.
Set PAR 14 according to the maximum
(10v) flow temperature required.
