LVI MEB Series, Instructions For Fitting And Use

Page: 4 / 9

ENGLISH
MEB = Radiator for fixed connection. Electronic thermostat with 4°C
temperature reduction facility. Delivered with connect-ing cable
with plug-in contact, wall socket alt. plug, wall brackets with
screws. Enclosure class IP 44.
Maximum surface temperature: 80°C.
MET = Same as MEB, but with built-in clock functions.
MES = Same as MEB, but without thermostat.
MEB60 = Same as MEB, but with low surface temperature: max. 60°C.
For bathrooms, daycare centres, etc.
MES60 = Same as MEB60, but without thermostat.
Installation
1.
The enclosed wall brackets are mounted to the wall with the enclosed
screws. The brackets are best placed approx. 100-150mm from the
ends of the radiator. Note that the brackets can also be used to measure
the height; see diagram 1.
It is important for the functioning of the radiator that it is mounted
vertically. The connection house should be positioned as per diagram 2
and the minimum distance should be observed.
The plastic hook can be fitted to the wall to coil up surplus cable. See
diagram 4A.
The radiator must not be placed immediately under a fixed wall socket
or so that a person using a bathtub, shower or swimming pool can
come into contact with live parts, e.g. the switch.
2.1
When the radiator is delivered with a wall socket and 5-pole plug, it
shall be connected by an authorized electrician. The wall socket is best
placed over a recessed socket or VP-tube behind the radiator. Refer to
the wiring diagram for the connection of the radiator.
Temperature reduction
MEB is fitted for a 4°C temperature reduction which is controlled by
either an existing switch or a central timer with separate control cable
(controlled N conductor). It is impor tant that the phase and N
conductor are correctly connected. MET has a temperature reduction
only with the built-in clock functions.
Slave coupling
Each radiator can function as a control or slave radiator. The total
output which the control radiator can regulate is 2300W. When slave
radiators are connected as per the wiring diagram the thermostat is
by-passed. If a slave radiator is connected on terminal block 1 in the
wall socket instead of terminal 4, the slave radiator’s thermostat is by-
passed.
NOTE! It is very important the plug is pushed fully into the wall socket;
see diagram 4B.
2.2
When the model designation ends with a P, the radiator is delivered
with an earthed plug and this shall then be connected to the existing
socket. It is not possible to use centrally controlled temperature
reduction and slave connections in this version.
Usage
4.
The radiator is switched on by putting the switch, which is marked I
and 0 , in position I .
5.
The required temperature is set by turning the red point on the
thermostat to this temperature. If the value on the thermostat dial
does not correspond to the ambient temperature this can easily be
adjusted. This is done by pressing the middle of the thermostat dial
with for example a pen. When this is pressed down the thermostat dial
is turned, so that the red point indicates the same temperature as the
ambient temperature, see diagram 5. The green lamp indicates that the
radiator is at full power.
3.
The top of the wall bracket can be pulled up and locked in its top
position to simplify the hanging of the radiator, see diagram 4 C. Make
sure that the top of the bracket grips the radiator to counteract lateral
movement.
6.
The radiator’s overheating protection disconnects the current if the.
radiator becomes too hot. Reset by switching the radiator off for 15
minutes.
In the event of repeated disconnection check that no parts are covered.
Otherwise contact your supplier.
8.1
MEB/MEB60 (see diagram 7)
When switch No. 1 is set in position
Ä
, the radiator heats up the room
to the set temperature.
When switch No.1 is set is position
d
, the temperature of the room is
reduced by 4°C from the set temperature on the thermostat and the
red lamp turns on. To return to the set temperature on the thermostat,
switch No. 1 must be set in position
Ä .
7.
The transparent cover can be locked to avoid unauthorized settings of
the radiator’s control functions, see diagram 6.
8.2
MET (see diagram 8)
When switch No.1 is set in position
Ä
, the radiator heats up the room
to the value set on the thermostat irrespective of how switches No. 2
and 3 are set, and without affecting previous programming. This position
is used for temporar y disconnection of previously programmed
temperature reductions. When switch 1 is set in position P, the radiator’s
temperature reducing functions are controlled by how switches No. 2
and 3 are set.
When switch 2 is set in position 7, the temperature of the room is
lowered by 4°C for 7 hours and will then automatically return to normal
temperature. This is repeated automatically at the same time each day.
The red lamp to the right of the switch turns on when a 7 hour reduction
is in progress.
When switch 3 is set in position 5 the temperature is reduced by 4°C
for 5 hours and then automatically returns to normal temperature.
This is repeated at the same time for five days in a run, then follow two
days without reduction. After 7 days, the same time sequence starts
again. The red lamp to the right of the switch turns on when a 5 hour
reduction is in progress.
If the switches are set in position 7 and 5 within an interval of 1 minute,
the radiator will reduce the temperature by 10°C from the set value
for 156 hours (6.5 days). After this it will heat up to the set value for 12
hours. If switch No. 1 is not set in position
Ä
within these 12 hours,
the radiator will return to a reduction of 10°C.
During power cuts of less than 5 minutes, the radiator retains the
programmed reductions. If a power cut is longer than 5 minutes and a
reduction program has been made, the radiator will start with a new
reduction period and the red lamps will flash, which implies that it
must be re-programmed.
8.3
MES/MES60
Radiators regulated by control radiator or other master control system.
Switching on and off takes place by means of the switch on the slave
radiator. For the slave radiator to release heat, the master control
system or control radiator must be switched on.
Maintenance
Use only mild detergents for cleaning and wiping of the radiator.
Miscellaneous
“Do not cover” implies that it must not be used for drying of clothes
by direct contact.
This radiator is filled with an exact volume of environmentally friendly
vegetable oil, so that repairs which involve the opening of the radiator
must only be carried out by the manufacturer or his representative.
Any leaks will be repaired by the manufacturer or his representative.
There are various optional auxiliary control systems, including locking
devices for the wall brackets. Radiators with the determination MEB/
MES60-502 and -504 can be equipped with a towel rail HDT-620 resp.
-980.
Two years warranty.
In the event of problems or repairs, please contact your supplier or
authorized electrician.
