Manual AEG FTE 5050 SN Thermostat

Manual

1. Applications

The electronic floor temperature controller is used for

controlling electric:

• direct floor heating

• floor temperature conditioning systems

Features

• Nighttime set-back, input for external clock

• Indicator lamps for "controller calls for heat" and for

set-back operation

• 2-pole mains switch

• Mounting in 55mm appliance socket

2. Description of functions

2.1 Functions

The floor temperature is set via the dial and is measured

by the remote sensor.

The scale of *…4 corresponds to a temperature of

10…40 °C.

Note: After switching on power supply, it may take some

time until an acceptable control quality will be

achieved.

Lamps

Red: Controller calls for heat

Green: Set-back mode is activated

2.2 Functions of the set-back input TA

èè

The TA input is used to set the thermostat into the ener-

gy saving mode (by using an external timer).

In this mode, the room temperature will be reduced by

3°C or 5°C (depending on jumper J2).

Caution-1!

The device may only be opened and installed ac-

cording to the circuit diagram on the device or these

instructions by a qualified electrician. The existing

safety regulations must be observed.

In order to comply with safety class II, the necessary

installation steps must be taken.

This independently mountable electronic device is de-

signed for controlling the temperature in dry and en-

closed rooms only under normal conditions. The devi-

ce confirms to EN 60730, it works according operating

principle 1C

2.3 Selecting the set-back temperature

By means of the J2 jumper it is possible to select 3°

or 5°.

J2 closed set-back by 5°C (factory pre-set)

J2 open set-back by 3°C

The temperature set externally via the dial is reduced by

this value.

2.4 Fault of the floor sensor

If a sensor fault (short-circuit or break) occurs, the con-

troller will switch to fault mode. The heating will func-

tion with max. 30 % of the energy (operation for 30 % of

the time). This provides frost- and overheat protection.

In the event of a sensor fault, both lamps will flash.

3. Electrical connection

Perform the steps described below:

• Pull off the temperature dial

• Release the fixing screw

• Remove the upper part of the casing

• Connect acc. to circuit diagram (see bottom of casing)

Floor sensor

The remote sensor must be mounted in such a way that

the temperature to be limited can be correctly re-

corded.

The remote sensor should be installed in a protective

tube. This will facilitate future replacement.

Do not install the sensor close to power lines. In other

cases a shilded cable has to be used.

The sensor can be extended to max. 50 m by means of

a cable suitable for mains voltage.

Caution!

The sensor lines are on mains voltage (230 V).
