English

The thermostat is an electronic on/off

thermostat for temperature control by means of

an NTC sensor located either externally or

internally within the thermostat. The thermostat

has a built-in ground fault circuit interrupter

(GFCI, Class A). The thermostat and GFCI are

dual mode, suitable for 120/240 V 50/60 Hz

power supplies.

The thermostat is for flush mounts in a wall

socket.

Product summary

Thermostats with built-in GFCI

088L5130 Programmable thermostat incl. floor

sensor and air sensor

Power module with built-in GFCI

088L5135 Power module (15A)

Mounting of floor sensor (fig. 3)

The floor sensor is used for floor temperature

regulation. To facilitate replacement, the sensor

can be installed in a tube positioned between

two runs of the heating cable. The tube should

be terminated at the floor surface and sealed.

If required, the sensor cable can be extended

up to approx. 100 m using standard installation

cable. Two wires in a multi-core cable used to

supply power for the heating cable must not be

used.

It is not intended that the temperature sensor

wire shall enter through the wall socket

mounting box, but enter through one of the

front holes (see fig. 7.) in the thermostat housing

outside of the mounting box.

The sensor cable shall be seperated from

LINE and LOAD cables. Can be separated in

conduite, inside or outside the wall. (see fig. 7).

Other approved floor sensors can be used if

they comply with the technical specifications

(see fig. 5).

Mounting of thermostat with air sensor

(088L5132) (fig. 4)

The air sensor is used for comfort temperature

regulation in rooms. The thermostat should be

mounted on the wall approx. 5.4 ft (1.6m) above

the floor in such a way as to allow free air

circulation around it. Draughts and direct

sunlight or other heat sources must be avoided.

Mounting of thermostat

Installation

TO AVOID ELECTRIC SHOCK, DISCONNECT

THE HEATING SYSTEM POWER SUPPLY AT

THE MAIN PANEL BEFORE INSTALLING THE

THERMOSTAT.

KEEP THERMOSTAT AIR VENTS CLEAN AND

FREE FROM OBSTRUCTION.

This thermostat is an electrical product and

must be installed in compliance with the

National and/or Local Electrical Code.

Installation must be performed by qualified

personnel where required by law. The

thermostat is equipped with a ground fault

circuit interrupter (GFCI, Class A) which requires

that the line and load cables are isolated from

one another for correct operation. The

thermostat is designed for resistive load. The

resistive load must not exceed 15 A (1800 W at

120 Vac / 3600 W at 240 Vac).

During a ground fault, both power feeds will be

disconnected.

Line terminals: L1 (L), L2 (N)

Delivers power from the service panel (breaker

panel or fuse box) to the thermostat.

This cable must only be connected to the

thermostat's line terminals, marked L1 (L) and

L2 (N).

Load terminals

Delivers power from the thermostat to the

heating cable or mat.

This cable or mat must only be connected to

the thermostat's load terminals, marked

"LOAD".

1. Use a screwdriver to release the catch (fig. 1),

and remove the front cover

2. Connect cables according to the diagram (fig. 2)

3. Mount the thermostat in the wall socket.

4. Carefully replace the front cover by first

positioning its upper edge and then clicking it

into place.

Floor sensor

The floor sensor must be connected to

terminals marked "sensor", terminals C and D.

(fig. 6).

Power module, 088L5135

If loads of more than 15 A are required,

expansion is possible using power modules.

Power modules can be connected to the line

cable and load cable, see above.

Maximum distance between thermostat and

power modules is 80 ft (25 m).

Use field wiring cable, recommended min. 20

AWG. Connect A to C and B to D (fig. 6).

Operation

088L5130/5132 (Programmable):

The first time the thermostat is connected,

time and day must be set. The thermostat will

automatically start up in the menu for setting

time and day.

088L5133 (Non-programmable):

The actual temperature setting is shown and the

thermostat is ready for use.

Checking the GFCI

It is important that the GFCI is checked for

correct installation and function.

To check the GFCI:

Testing can only be performed while the

thermostat is calling for heat.

Adjust the setpoint until the heating symbol (

appears. Use the "Up" button to increase the

heating demand and then press the "OK"

button. Wait 10 seconds to allow the thermostat

to adjust to the new setpoint.

Then press the "TEST" button.

The test is successful if the red light in the

"TEST" button lights up and "GROUND FAULT"

is shown on the display. If this does not occur,

check the installation.

Press the "Standby/Reset" button to reset the

GFCI.

The red light should go out and the display

returns to normal appearance.

Press the "Down" button to return to the original

temperature setting.

If the test fails, check the heating cable and

thermostat.

The GFCI should be tested monthly.

If during normal operation the GFCI trips

without the "TEST" button being pressed, there

could be a ground fault! To check whether it is a

ground fault or nuisance tripping, press

"Standby/Reset". If this causes the red light to

go off and stay off, it was nuisance tripping and

the system is operating correctly. If this does

not occur, there is a ground fault!

Check the heating cable, sensor cable and

thermostat. Replace the defective part.

Programming the thermostat (if applicable)

See user manual.

Floor sensor faults

If the floor sensor is disconnected or short-

circuited, the heating system is switched off.

The sensor can be checked against the

resistance table (fig. 5).

Error codes

E0: Internal error. The thermostat must be

replaced.

E1: Air sensor short-circuited or disconnected.

The thermostat must be replaced (n/a for

088L5133)

E2: Floor sensor short-circuited or

disconnected.
