. OPERATING INSTRUCTIONS OF YOUR

TOWEL RAILS

To make the most of your towel rail and for greater comfort, we would

ask you to take the following recommendations into account:

The appliance must be installed on a vertical wall and the power cable

must be located at the bottom.

· The radiator should be mounted on a vertical wall with the connection

cord at the bottom of the radiator,

· The lower part of the radiator must be within a minimum distance of

150mm from the ground,

· The radiator must not be installed within 50mm of a wall or under

-

neath a power outlet,

· Improper installation of a shelf above the radiator must be carried out

over 150mm of it,

· It is recommended to perform the installation, if possible, close to lo

-

cations with high heat losses (windows etc) and using screw fasteners

appropriate to the nature of the wall,

· Drill and plug the 4 xing holes in a suitable location,

· Secure the radiator to the wall using the screws 3 or 4 xing holessup

-

plied,

· Make the electrical connection.

. POSITIONING

• The diagrams below show the appliance’s correct positioning.

• For bathroom installations the appliance must be installed outside

zone 1 with the electrical connection outside zone 2 (see diagram

below), in accordance with the latest electrical safety regulations, and

in such a way that the controls cannot be reached by a person using

the bath or shower,

. BRACKETS

For the correct installation of radiators it is essential that the

xing of the radiator is carried out in such a way that it is

suitable for intended use AND predictable misuse. A number of

elements need to be taken into consideration including the

xing method used to secure the radiator to the wall, the type

and condition of the wall itself, and any additional potential

forces or weights that may happen to be applied to the radia-

tor, prior to nalising installation.

. For correct heater installation, when the appliance is located

close to a wall, it is essential to leave a minimum distance of

250 mm to access the installation.

• Use bracket screws suited to your type of wall, secure the

heater on the wall using the screws

provided with the towel rails.

• The towel rail must be installed on a vertical wall using the

wall mounts supplied.

• The towel rails’ mounting components are adjustable verti-

cally, horizontally and as regards depth (see

exploded diagram in the box), which makes correct installa-

tion easier. Positioning can be seen from

the gure on the drawing page.

Overview

Lowering temperature cycle by setting frost protection during venti-

lation of a room by opened window. You can access the open window

detection from the Comfort, Eco and Auto modes. Two ways to enable

the detector:

- Automatic activation, the lowering temperature cycle starts as soon

as the device detects a temperature change.

- Manual activation, the cycle of lowering temperature starts by pres

-

sing a button.

Automatic activation (factory settings)

To disable this mode, see page 14.

The device detects a temperature fall. An opened window, a door to the

outside, can cause this temperature fall.

Note: The diﬀerence between the air from the inside and the outside

must cause a signicant temperature fall to be perceptible by the device.

This temperature drop detection triggers the change to Frost Protection

mode.

Manual activation

By pressing for

more than 5 seconds,

the device will switch on

Frost protection mode.

Frost protection digital meter

When the device performs a lower temperature cycle due to opened

window, a meter appears on the display to show the cycle time.The

counter is automatically reset at the next time to Frost protection by

opened window (automatic or manual activation).

Stop the Frost protection mode

By pressing one button, you stop the Frost protection mode.

Note: if a temperature rise is detected, the device may return to the

previous mode (active mode before the open window detection).

INFORMATION ABOUT REMOTE CONTROL

BY PILOT WIRE

• Overview

Your device can be controlled by a central control unit through a pilot

wire, in which case the diﬀerent operating modes will be remotely en

-

abled by the programmer.

You can only control the device by pilot wire in the Auto mode. In the

other modes, the orders transmitted by the pilot wire will not be exe

-

cuted.

In general, a pilot wire control system makes it possible to impose exter

-

nally a lowering of the temperature setpoint, combined with the inter-

nal programming and the occupancy detection.

If several lowering requests appear simultaneously, priority is given to

the lowest temperature setpoint, thus maximizing savings (see infor

-

mation on priorities for diﬀerent modes on page 11).

When a signal is sent from the pilot wire, the self learning optimization

function is suspended.

Below the diﬀerent views of the display for each order sent by pilot wire:

• Load shedding

In case of over consumption, an energy power manager or a disconnec-

tor doesn’t trigger a trip of the general circuit-breaker (example: simul-

taneous operating of your various household appliances and others).

This allows you to reduce the energy power subscribed and therefore

optimize your subscription with your energy provider.

This thermostat is designed to operate with pilot wire load shedding

systems.

Orders sent by the pilot wire are executed by the device’s electronic

controller which will apply the setpoint corresponding to the order sent.

The "Stop" order corresponds to the load shedding. When this order is

received, the device switches to "standby" and then returns to the initial

operating mode.

Important: Do not use load shedding by a power fail. Unlike

pilot shedding, this type of shedding results in a series of sud

-

den and frequent power cuts, which cause premature wear of

the device or even deterioration not covered by the manufac

-

turer’s warranty.

INFORMATION ABOUT PRIORITIES BETWEEN

THE DIFFERENT MODES

In Comfort, Eco and Frost protection modes, only orders of the open

window sensor will be considered.

In Auto mode, the device can receive diﬀerent orders coming from :

- 7 day and daily programming integrated (Comfort or Eco orders);

- 6-order pilot wire, if connected to central control unit;

- Open window detector.

Principe

In general, it is the lowest received order which prevails except

when the pilot wire is connected to an energy management system, in

this case the orders of the pilot wire take priority.

In case of programmed Boost, the Boost activation will take precedence

over others orders received except when the standby (stop) order is pre

-

sent on the pilot wire, the device will switch oﬀ and the Boost will be

not activated.

Overview

Your heating device is protected by a safety code against nonauthorised

use. The PIN code (Personal Identity Number) is a

customisable 4 numbers code. When enabled, it prevents access to the

following settings:

- Selecting the Comfort mode : The access to the Comfort mode is

forbidden, only the Auto, Eco and Frost protection modes are available.

- Minimum and maximum Limits of the setting temperature range (the

Comfort temperature modication is forbidden out of the authorised

setting range).

- Programming mode.

- Open window detection settings.

- Setting the Eco mode temperature lowering-level.

- Setting the Frost protection temperature.

3 important steps are needed for the rst use of the PIN code lock:

1 - PIN code initialisation, enter the preset PIN code (0000) to access to

the feature.

2 - Activation of the PIN Code to lock settings which will be protected

by the PIN code.

AMBIENT TEMPERATURE SENSOR ADJUSTEMENT

Overview

Important: This operation is reserved for professional installers only;

any wrong changes would result in control anomalies.

In which case if the temperature measured (measured by reliable ther

-

mometer) is diﬀerent by at least 1°C or 2°C compared to the setting

temperature of the radiator.

The calibration adjusts the temperature measured by the ambient tem

-

perature sensor to compensate for a deviation from + 5°C to - 5°C by

intervals of 0.1°C.

Important: Before carrying out the calibration it is recommended to

wait for 4h after the setting temperature modication to insure that

the ambient temperature is stabilized.

Ambient temperature sensor adjustement

1- If the room temperature diﬀerence is negative, example :

Setting temperature (what you want) = 20°C.

Ambient temperature (what you read on a reliable thermometer) =

18°C.

Diﬀerence measured = -2°C.

To correct, then proceed as follows :

Sensor temperature = 24°C

(The measured temperature may be diﬀerent due to the location of the

thermostat in the room).

Decrease the temperature measured by the ambient temperature sen

-

sor by 2°C by pressing

.

In our example the measured temperature by the sensor goes

from 24°C to 22°C.
