“MURELLE EQUIPE 100-150 BOX (M)”

heat modules can be installed in boiler

rooms whose size and requirements meet

current regulations.

VENTILATION

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.

Ventilation requirements for Murelle HE

110 R boilers and cascade systems.

BS6644 has a requirement that the tem-

peratures in a room or compartment do

not exceed certain levels:

25°C at floor level(0-100mm)

32°C at mid level (1.5M above the floor level)

40°C at ceiling level (0-100mm from ceiling)

Low level (low as possible within 1 metre

from floor natural gas, 250mm LPG) –

10cm²/KW of net heat input.

A single generator (48KW net input) would

require 240cm² at high level and 1480cm²

at low level.

2.2.2 Outdoors

“MURELLE EQUIPE 100-150 BOX (M)”

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 vol-

ume (consumption) in m

3

/h and gas den-

sity 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

identification 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.

2.6 EXHAUST FOR OUTDOOR

INSTALLATION (fig. 5)

The exhaust terminal for single module

code 8089530 is required for this type of

installation. For separately supplied acces-

sory assembly see fig. 5.

2.7 INDOOR INSTALLATION

EXHAUST KIT (fig. 6)

Refer to fig. 6 for this type of installation.

The indicated solutions have the exhaust

manifold positioned both on the modules.

It is however possible to move the exhaust

of the left by simply rotating the manifold

180°.

NOTE: The kits are purposely treated also

to resist weathering when installed out-

doors.

WARNING: In models “100-150 BOX

(M)” the tubes connecting hydraulic sepa-

rator 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 con-

tacts. Observe the L – N polarity and

grounding 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.

NOTICE: The external temperature probe (SE) must be connected to the MASTER

generator and the cascade supply probe (SMC) to the SLAVE 1 generator.

The SE, SMC probes and the RS-485 board connection cable are supplied togeth-

er with the modules in the probe kit code 8092250.

2.11.2 Electrical connection of generators in sequence/cascade (fig. 11/a)

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 (

and ) for 2 seconds.

Having entered the INST level, press (

and ) simultane-

ously for another 2 seconds. At this point insert the access

code formed by this sequence of INSTALLATOR BUTTONS:

“ + / - / < / > / < “.

Set the parameter:

PAR A1 = Number of cascade generators (3 ... 8)

x 2

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 con-

forming to the standard EN 607301 (clean

electrical contact).

2.11.4 Climatic regulator CR53 connec-

tion (optional)

The heating demand can be controlled

by use of a climatic regulator (code

8092227), for the management of the

heating circuit. The generators will still dis-

play information. For installation and use of

the regulator, follow the instructions includ-

ed in the packaging.

NOTE, reset parameter 10 to 2 (PAR 10 =2)

2.11.5 Remote control CR 73 connec-

tion (optional)

The heating demand can be controlled by

use of remote control unit CR 73 (code

8092226)

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)

2.11.6 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.

2.11.7 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.

2.11.8 BMS (Building Management Sys-

tems)

The cascade of generators can be con-

trolled 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.
