1. Intended Use

The radio-controlled radiator thermostat set comprises of three components:

• the FHT 80b Wall Thermostat (heating control),

• the FHT8V Actuator (valve operating mechanism), and

• the FHT 80TF Door / Window Contact Sensor (sold separately).

The system is used for temperature control in individual rooms in which the heat that dissipates from radiators is controlled by reducing the flow of hot water in the heating system.

The FHT 80b heating control measures the room temperature by means of an integrated sensor and transmits the corresponding control data to up to eight FHT 8V valve operating mechanisms (i.e. max. 8 radiators per room)

The FHT 80b can analyze the status signals (window open/closed) of up to four FHT80 TF door/window contact sensors and, in order to save energy when a room is aired, automatically reduce the temperature down to a socalled ‘Window open’ temperature, when the room’s window is opened.

The FHT 80b also facilitates a bi-directional radio connection with the FHZ 1000 House Central Unit.

Any other use (e.g. in cooling systems, floor heating systems, etc.) is not permitted and may lead to severe damages.

2. Description and Function

Compared with simple mechanical thermostats (a.k.a. TRVs), the radiocontrolled radiator thermostat systems have a number of advantages:

• the split between the radiator-mounted valve operating mechanisms and the freely positionable operation and control units (e.g. the FHT 80b heating control which is part of the scope of supply) makes it possible to perform settings easily.

• the programming option makes it possible to adapt the system to the lifestyle of its users, so that the room is always comfortably warm when it is used. When the room is not used, the temperature may be reduced automatically to save energy, i.e. the often cumbersome manual opening and closing of heating valves is no longer required.

• the system is equipped with an integrated calcification protection. Once every week (time can be set) the valve operating mechanism opens and closes the valve to prevent blocking of the valve by lime deposits.

2.1.Operating principle

In the FHT 80b heating control, the room temperature is measured and compared to the desired temperature (set either by means of the time program or manually). The difference is used to calculate how far the valve has to be opened or closed to obtain the desired temperature. Using time interval of approximately two minutes, the radio commands are sent to the FHT 8V valve operating mechanism mounted on the radiator. This valve operating mechanism then reduces or increases the heat. Heating up of a room takes some time, depending on the size of the radiators. If the desired temperature is changed, the room temperature changes with a certain delay. Deviations between the desired value and the room temperature may also be caused by various disturbance variables, such as draughts, other sources of heat in the room, or an insufficient supply of heat from the heating boiler. Temperature measurement within the control is very exact (deviation <1*C). To avoid any unnecessary operation of the valve, e.g. when the room temperature changes temporarily because a door is opened, several measured values are averaged during the two minutes communication gap.

The heating control’s integrated receiver also allows the FHT 80b to receive the status signals from up to four FHT 80TF door/window contact sensors.

Changes (‘Window open’ or ‘Window closed’) are signaled to the heating control within a time period of about 1 minute. This allows the heating control to adjust the temperature after an average of 30 seconds, in order to save energy when, for example, a room is aired.

2.2.Safety code

The radio signal is protected by a safety code consisting of two parts. This safety code protects the system against interference from other radio systems and ensures that several radio-controlled radiator thermostat systems can be operated separately in a household. Each part of the code comprises 100 setting options. This means that there are 10,000 different safety codes available. To ensure communication between the heating control and the valve operating mechanism/s the same safety code has to be set for all devices in a room.

To ensure communication between the heating control and the valve operating mechanism(s) the same security code has to be set for all devices in a room. A random security code is set by the manufacturer.

When supplied as a set (heating control and valve operating mechanism) the valve operating mechanism is preset to the heating control’s security code.

If you purchased the heating control and valve operating mechanism separately (or you want to use additional valve operating mechanisms for a heating control), then the security code has to be transmitted to each of the valve operating mechanisms. See section 9.4. or section 9.5.

The security code is also used for communicating with the FHZ 1000 central unit and the FHT 8W Heat Demand Relay.

The FHT 80TF door/window contact sensors are equipped with a randomly generated factory default code that cannot be changed. Since there are over 16 million different possible codes, changing the code of the door/window contact sensor is not necessary; duplication is virtually impossible.

2.3.Information on the range

The transmission power is less than 10mW, much below that of a mobile phone which may have a transmission power 200 times as great. Adverse effects on sensitive people and animals are not to be expected.

The wireless radiator thermostat system uses the 868MHz range, which is also used by other radio services. Therefore devices that operate on the same or neighboring frequencies may restrict both its operation and its range.

The specified range of up to 100m (to the ‘FHT8V’ valve operating mechanism) or up to 300m (to the ‘FHZ1000’) is the free-field range, which means the range with visual contact between the transmitter and receiver. In practice, however, walls, ceilings, etc. between the transmitter and the receiver may affect and reduce the range.

Other causes of reduced ranges:

• All types of high-frequency interference

• Any buildings or vegetation

• Conductive metal parts that are located near the devices or within or near their transmission path, for example, radiators, metallised insulation glass windows, reinforced concrete ceilings, etc.

• Influence on the radiation pattern of antennas due to the distance from the transmitter or receiver to conductive surfaces or objects (also to human bodies or the ground)

• Broadband interference in urban areas that reduces the signal-to-noise ratio; the signal is no longer recognised due to this ‘noise’

• Interference radiation resulting from insufficiently shielded electronic devices, for example, operating computers or similar

8. Programming the System

8.1. Setting the comfort temperature, lowering temperature and the

‘Window open’ temperature

When the automatic mode has been activated and switching between the lowering temperature and the comfort temperature is performed automatically, a bar in the lower part of the display indicates the time of day at which the temperature will be set to the comfort temperature. A sun symbol on the display indicates that the comfort temperature is active; a moon symbol indicates that the lowering temperature is active. If one or several FHT 80TF door/window contact sensors are installed in a room, then the so-called ‘Window open’ temperature is automatically activated after the monitored door or monitored window has been opened (irrespective of which operating mode has been set). Proceed as follows to change the settings:

Press and hold the ‘ ’ button longer than 3 seconds. The comfort temperature is displayed on the LCD. The sun symbol ‘ ’ blinks.

8.2.Setting / changing the weekly profile

The time for automatic switching between the comfort temperature and the lowering temperature can be set separately for each day of the week. That way you may adapt the desired room temperature to your individual lifestyle.

For each day of the week, four switching times (comfort temperature on, lowering temperature on, comfort temperature on, lowering temperature on) can be set. These 4 switching times can be different for each day of the week. This makes it possible to start heating later on weekends or on certain days of the week.

• Briefly press the “PROG” key.

• “Prog” is displayed

9.4. Setting the security code (‘CodE’)

To protect the heating control against interference from other radio systems the device uses a two-part security code. Each part of the code comprises 100 setting options. This means that a total of 10,000 different security codes are available. To ensure communication between the FHT 80b heating control and the FHT 8V valve operating mechanism(s) the same security code has to be set for all the devices in a room. This is particularly important, if you use more than one valve operating mechanism or you have not purchased a set (heating control and valve operating mechanism).

Proceed as follows to change or set the code:

• Press the ‘PROG’ button until ‘Sond’ appears in the LCD.

• Use the scroller to select the ‘CodE’ function.

• To confirm your selection, briefly press the ‘PROG’ button.

Now you need to synchronise the (first) valve operating mechanism (‘001’ on the display) to the new security code. Proceed as follows to carry out this synchronisation:

• Remove the battery compartment cover of the (first) valve operating mechanism by sliding it down.

• Press the button on the valve operating mechanism for approx. 3 seconds until you hear 3 signal tones. The valve operating mechanism is now ready to receive and ‘AC’ is displayed.

• Press the ‘PROG’ button on the ‘FHT80B’ heating control to start transmitting the security code to the valve operating mechanism.

• The valve operating mechanism acknowledges that it has received the code correctly with a tone sequence.

• Replace the valve operating mechanism’s battery compartment cover.

• The valve operating mechanism acknowledges that it has received the first normal radio signal with a signal tone.

Now repeat these steps for all the other valve operating mechanisms in the room (‘002’, ‘003’... on the display).

After the last valve operating mechanism has been coded the heating control automatically returns to the normal operating mode. If the heating control is used to control several valve operating mechanisms, in other words, several radiators are located in one room, you should make a note of which valve operating mechanism belongs to which radiator, that means the number. If coding of a valve operating mechanism fails (for example, due to bad reception, a low battery or similar), the security code can be transmitted to this valve operating mechanism again at a later time.

• Proceed as described above and skip the valve operating mechanisms that have already been coded by briefly pressing the ‘PROG’ button.

• If the LCD shows the number of a valve operating mechanism that has not yet received a security code, press the control button on this valve operating mechanism until ‘AC’ is displayed on the valve operating mechanism and you hear 3 signal tones. Also see the information above.

• Now press the ‘PROG’ button on the heating control to get the heating control to transmit the security code. The valve operating mechanism uses a tone sequence to acknowledge that it has received the code correctly.

Afterwards, replace the valve operating mechanism’s battery compartment cover. The valve operating mechanism uses a signal tone to acknowledge the first receipt of a normal radio signal.

9.5.Setting the number of valve operating mechanisms (‘An A’)

You use this menu item to set the number of radiators (valve operating mechanisms) to be controlled when the heating control is used to control several valve operating mechanisms in one large room, for example.

If you install an additional valve operating mechanism, you must ensure that this valve operating mechanism is assigned the same security code as the valve operating mechanisms, which are already installed.

• Press the ‘PROG’ button until ‘Sond’ appears in the LCD.

• Use the scroller to select the special ‘An A’ function.

• To confirm your selection, briefly press the ‘PROG’ button.

The (first) valve operating mechanism is now synchronised to the new security code. ‘CodE SynC 001’ appears on the heating control’s LCD.

Repeat the following 6 steps (see next page) for each installed valve operating mechanism:

1. Remove the battery compartment cover of the (first) valve operating

mechanism by sliding it down and out.

2. Press the button on the valve operating mechanism for approx.3 seconds until you hear 3 signal tones. The valve operating mechanism is now ready to receive and ‘AC’ is displayed.

3. Press the ‘PROG’ button on the heating control to start transmitting the heating control’s security code to the valve operating mechanism.

4. The valve operating mechanism acknowledges that it has received the code correctly with a tone sequence.

5. Replace the valve operating mechanism’s battery compartment cover.

6.Thevalveoperatingmechanismacknowledgesthatithasreceivedthefirstnorm alradio signal with a signal tone.

Repeat these 6 steps for all the other valve operating mechanisms that are located in the room (‘002’, ‘003’ ... on the display) according to the number of valve operating mechanisms that has been set.

Once all the valve operating mechanisms have been coded the heating control automatically returns to the normal operating mode.

You can skip any valve operating mechanisms that have already been synchronised / programmed to the heating control’s security code.

All you need to do is briefly press the ‘PROG’ button on the heating control (do not open the respective valve operating mechanism/do not press the button on the valve operating mechanism!)

9.6. Synchronising the valve operating mechanisms (‘SYnC’)

When this menu item is selected, the heating control starts to signal (for approx. 2 minutes) to all the valve operating mechanisms that they should resynchronise.

Afterwards the normal transmission program is continued and the valve operating mechanisms generate a signal tone as soon as they receive the first correct signal.

• Press the ‘PROG’ button until ‘Sond’ appears in the LCD.

• Use the scroller to select the special ‘SynC’ function.

• To confirm your selection, briefly press the ‘PROG’ button.

• The LCD then displays the security code and the heating control counts down from ‘120’ in steps of 1 second. After these 120 seconds the heating control returns to the normal operating mode.

9.7. Test mode (‘tESt’)

You can use this function to check whether all the valve operating mechanisms receive the radio signal correctly. The addressed valve operating mechanisms acknowledge correct reception with an acoustic signal. Use the scroller to select the valve operating mechanisms to be tested.

If the large display shows a ‘0’, then all the receivers are tested, otherwise, only the valve operating mechanism assigned to the displayed number is tested. The timer in the left corner of the display counts down to the time at which the next test cycle is to be started.

• Press the ‘PROG’ button until ‘Sond’ appears in the LCD.

• Use the scroller to select the special ‘tESt’ function.

• To confirm your selection, briefly press the ‘PROG’ button.

• Use the scroller to select the valve operating mechanism/s to be tested.

• Press the ‘PROG’ button to quit the test function. h) Displaying the valve position (‘StEL’) When you select this menu item the heating control’s LCD indicates how far the valve is opened as a percentage (only for valve operating mechanism 1).

• Press the ‘PROG’ button until ‘Sond’ appears in the LCD.

• Use the scroller to select the special ‘StEL’ function.

• To confirm your selection, briefly press the ‘PROG’ button.

• The display shows the valve opening as a percentage (only possible for valve operating mechanism 1).

• Press the ‘PROG’ button to quit this function.

9.8.Connecting to the home radio central unit (‘CEnt’)

You only require this special function, if you want the heating control to work with a new FHZ1000 central unit or no central unit at all, in other words, you wish to unregister the heating control from the central unit.

Radio communication between the heating control and the central unit is also protected by the heating control’s security code. For this purpose the respective heating control is ‘registered’ with the central unit.

To ensure that the heating control only works with your central unit and not with your neighbor's central unit, for example, the heating control can only be registered with one central unit.

If you want to register the heating control with another central unit, then you must first to re- enable the heating control. 3 different settings are possible:

‘On’: Heating control is registered with the central unit

‘Off’: No radio communication with the central unit. Registration is not possible.

‘nA’: Heating control is enabled for registration with the central unit

To set, proceed as follows:

• Press the ‘PROG’ button until ‘Sond’ appears on the LCD.

• Use the scroller to select the special ‘CEnt’ function.

• To confirm your selection, briefly press the ‘PROG’ button.

• The LCD displays the current setting (‘On’, ‘Off’, ‘nA’).

• Use the scroller to select the setting you require (‘On’, ‘Off’, ‘nA’) and confirm your selection by pressing the ‘PROG’ button. The heating control then returns to the normal operating mode.

9.9. Querying the status of a door/window contact sensor (‘FEn’)

You can use the ‘FEn’ special function menu to request the current status of a FHT 80TF door/ window contact sensor. You can also use this menu to newly register or delete door/window contact sensors.

Proceed as follows to access the door/window contact sensor’s menu:

9.11. Deleting door/window contact sensors

Door/window contact sensors that are no longer required or are no longer in operation should be deleted in order to avoid repeated error messages from being displayed (‘reception failure’). The power consumption also increases as attempts are regularly made to receive signals from the door/window contact sensors.

Proceed as follows to delete a door/window contact sensor:

• Press the ‘PROG’ button until ‘Sond’ appears on the LCD.

• Using the scroller, select the special ‘FEn’ function.

• To confirm your selection, briefly press the ‘PROG’ button.

• Using the scroller, select the door/window contact sensor that you wish to delete.

• Keep the ‘ ’ button pressed until the status is displayed as ‘not registered’ (‘nicht angemeldet’, ‘nA’):

• Briefly press the ‘PROG’ button to quit the status indicator. The heating control returns to the normal operating mode.

9.12. Radiator offset (‘OFFS’)

This setting option is only displayed, if you use more than one valve operating mechanism. If several radiators are controlled by one heating control, it may be that these radiators do not heat up to the same level.

The reason for this is that the flow rates of the valves differ greatly, depending on varying or poorly dimensioned radiators. This problem may be solved by

You may have to repeat this process several times until the heating power has been optimally distributed.

10. Replacing the batteries

10.1. FHT 80b Wall Thermostat (heating control)

If the ‘

’ symbol appears on the LCD, this means that the batteries are low

and must be replaced.

To replace the batteries, proceed as follows:

• Remove the heating control from the wall holder and open the battery compartment cover (slide down).

• Remove the batteries from the battery compartment and dispose of them according to the applicable environmental regulations. See section 16, page 39.

• Insert two new AA batteries; make sure the polarity is correct. If possible, use alkaline batteries.

• Close the battery compartment.

• If a FHZ 1000 central unit is present, the heating control automatically requests the current time and date and then sets these. Otherwise you need to set these manually. The time program settings, the comfort/lowering temperature settings and so on are maintained.

• As the heating control and the valve operating mechanism are no longer synchronised with each other, the heating control performs a synchronisation procedure (‘SYnC Auto’) that lasts approx. 2 minutes. After this synchronisation the heating control returns to the normal operating mode.

10.2. FHT 8V Actuator (valve operating mechanism)

The battery symbol appears when the valve operating mechanism’s batteries are low. In addition, an acoustic signal is generated every 2 minutes for one hour, three times a day.

To replace the batteries, proceed as follows:

• Remove the battery compartment cover from the valve operating mechanism by sliding it down.

• Remove the old batteries and dispose of them according to the applicable environmental regulations. See section 16, page 39.

• Wait until all the segments of the valve operating mechanism’s LCD have gone out. You can speed up this process by keeping the button on the valve operating mechanism pressed.

• Insert two new AA batteries into the valve operating mechanism’s battery compartment, making sure that the polarity is correct. Otherwise you may destroy the valve operating mechanism’s electronic components!

• The display shows ‘C1’ followed by a 2-digit number. The display then shows ‘C2’, followed by another 2-digit number (both numbers are the currently stored security code of the valve operating mechanism).

• A signal tone is then generated and ‘A1’ is displayed.

• The valve operating mechanism now fully retracts the control pin.

• ‘A2’ is then displayed.

• Briefly press the button on the valve operating mechanism.

• ‘A3’ is displayed and the valve operating mechanism closes the valve completely.

• The antenna symbol then blinks and ‘0%’ is displayed.

• The first radio signal that is received is acknowledged by a signal tone, and the antenna symbol is permanently displayed.

• Replace the battery compartment cover.

10.3. FHT 80TF Door / Window Contact Sensor

When the batteries in the door/window contact sensor are low, the device sends this information to the heating control. The corresponding error message (the window icon blinks) is shown on the heating control’s display. You can use the ‘FEn’ special function menu to identify the door/window contact sensor whose batteries are low.

To replace the batteries, proceed as follows:

• Open the casing by pushing the two catches on the left side of the casing approx. one millimeter inwards using a flat screwdriver while simultaneously pulling the lid forwards.

• Remove both of the old batteries and dispose of them according to the applicable environmental regulations. See section 16, page 39.

• Insert 2 new AAA batteries into the battery compartment, observing the correct polarity.

• Close the casing cover.

• If necessary, the door/window contact sensor now conducts a synchronisation procedure that lasts approx. 1 minute (the LED blinks every second).

12. Handling

Protect the product against humidity, cold, heat, dust, and direct sunlight.

Do not disassemble the product. Have any repairs per- formed by experts, otherwise the license (CE) of the product will lapse!

Do not drop the product, it will be damaged even if it falls from a low height.

13. Maintenance and cleaning

The product does not require any maintenance apart from replacing of batteries. Clean the product with a soft, clean, dry and fuzz free cloth. To achieve a better cleaning action the cloth can be dampened with lukewarm water. Take care not to let any moisture get into the product! Do not use cleaning agents containing solvents, since these may damage the plastic housing and labeling.

14. Information about radio operation

Transmission of data between heating control and valve operating mechanism is performed wirelessly per radio transmission.

The transmitting power is less than 10mW, i.e. much below the transmitting power of a mobile phone which may have a transmitting power that is 200 times as great. Therefore, negative effects on sensitive people or animals are not to be expected.

The radio heating thermostat system works in the 868MHz range which is also used by other radio services. There- fore restrictions in the operation and the range can occur through the devices which work on the same or neighboring frequency.

The range stated of up to 100m is the free-field range, i.e. the range at sight contact between the transmitter and the receiver.
