2. DescriptionTA is a basic thermostat specially designed for underfloorheating. It provides the following features and functions:

floor sensor or integrated room sensor.

Extra terminal which can be used as an external closingcontact to reduce the set temperature by 3,5°C

The set temperature can be increased by 5°C for 2 hours.Reverts automatically to the original temperature setting

thermostat at the touch of the buttons

and cut off the heating output during sensor fault (fail-

safe)

3. Mounting and installationThermostatTA is intended for flush mounting in a standard 65 mmwallbox. It should be positioned approximately 1,5 metresabove the floor, protected from direct sunlight and draughts.

All electrical conduits passing into the thermostat box thatcontain cables must be sealed to protect the thermostatagainst any draughts, e.g. with a piece of insulation in theconduit outlet.TA can also be mounted in an external wall box. If thethermostat will be mounted on a rough wall surface, e.g.bricks, put a string of silicon glue under the top frame.Assembly frame and front can be exchanged by pushingwith a screw driver on two knobs, placed on the sides of thethermostat. (Fig. 2)

Floor sensorThe floor sensor should be installed in a separate flexibleconduit/hose for easy replacement. For best controlperformance, position the floor sensor between two heatingcables as close as possible to the top floor surface. Do not

position the floor sensor tip closer than 3 cm to the heatingcable.The floor sensor cable can be extended to 100 m with aseparate standard installation cable 2 x 1.5 mm2 (min.)(230VAC). In order to avoid signal disturbance resultingin a possible malfunctioning of the thermostat, the sensorshould not be installed in a conduit together with otherpower carrying cables.

Connection of the thermostatThe thermostat must be connected to 230VAC according tothe circuit diagrams. When connecting multiple heaters tothe thermostat where the combined total load is above 13A,you are required to use a contactor or switchgear.If the protective earth terminal, (PE) on the thermostat isused, the incoming power cable to the heating cable shall be

connected to the common earth terminal on the thermostat,otherwise a separate terminal connection block (notincluded) must be used.

Product specific information for use with floorheatingsystems

Use with T2QuickNet: The T2QuickNet product line is approved with the

thermostat working in floor sensor mode. Be aware thatthe floor sensor must be installed and activated for aninstallation with T2QuickNet.

Use with T2Red (T2Reflecta) self-regulating systems: Self-regulating heating cables have an inrush currentat start up. In order to guarantee the life time of thethermostat, the maximum load of the self-regulatingapplication in nominal conditions is limited to 10A.

A 13A self-regulating load will reduce the life time of therelay contacts.

sensor cable is not connected, it operates in room sensormode.

After 5 sec. the thermostat checks if an external controlsignal is connected.If yes, the thermostat will be controlling according to the

set temperature and external signal. The symbol AUTO isactivated. If not, the thermostat will be controlling accordingto the set temperature.

Adjust the set temperature, desired floor temperature orroom temperature, with the < > buttons. This is anapproximate set value to get a comfort temperature on thefloor or in the room.

Heating-on symbol < > indicates on the display when theheating cable is on.

Learning Function

This function starts only if the thermostat has no floorsensor connected, (‘Er3’ at start-up) only in ambient sensing

mode configuration.

At the first thermostat power-up (or after a factory reset),the thermostat begins its own regulation parametercalibration.During this learning time, the user doesn’t have access toambient temperature:

Instead of temperature, a count down timerfrom 2.1 hours to 0.1 hour(0.1 hour = 6 minutes) is displayed.

The learning time is divided into two steps:

1. Time < 30min (0.5 hour) [ from 2.1h to 1.6h]:the first half hour, the user is allowed to changethe set temperature and activate the floor warmingsystem. This period can be used by the



12

installer to check the floor warming systeminstallation. The set temperature can be adjustedby using +/- keys.

2. 30min < Time < 2hours [from1.6h to 0.1h]:The thermostat doesn’t take into account the settemperature. But during this period, the thermostatcan power on and off the floor warming system toadjust its regulation parameters.

If there is a main power supply loss during this learningperiod (main switch off or power supply failure), thethermostat will restart the learning function.

At the end of this learning function, the thermostat isautomatically calibrated (adapted to the load linked tothe thermostat): Internal offset

Compensation

This function will run at every factory reset of thethermostat.

14

In floor sensing mode, the user sees the room temperature Floor temperature [Installer menu n°1]

– Offset [Installer menu n°2]= Room temperature (seen on the thermostat)

The thermostat has an ‘OFF mode’. In this stand-by mode,the floor heating is not powered at all. The thermostatscreen will display the actual measured room temperature.In the summer time, in this 'OFF mode', the thermostat actsas a thermometer only.To go to the ‘OFF mode’ press simultaneously the< > keys for more than 1 second. Repeat this step toexit this mode.

The off mode is available only after the end of the firstwarming function and after the learning function. When oneof these functions is in progress the thermostat can powerup the floor warming system even if the thermostat is in off

mode.

Working description:To activate this option the user enters the installer menu

number 4 and selects the configuration (‘on’ or ‘off’) andvalidate.

When the thermostat comes back to the normal mode, theuser sees instead of the temperature, the remaining numberof days of the progressive warming (total duration: 21 days).

During this time, the thermostat warming cycle is equal to24 minutes (60 cycles per day).

The first day, the thermostat powers the

floor heating system during 1 minute oneach 24 min cycle (= 1h of warming thefirst day).

The second day, the thermostat powers thefloor heating system during 2 minutes oneach 24 min cycle (= 2h of warming thesecond day).

Before the last day, the thermostat powersthe floor heating system during 19 minuteon each 24 min cycle (= 19h of warmingthe first day).The last day, the thermostat powers thefloor heating system during 20 minute oneach 24 min cycle (= 20h of warming thefirst day).
