Mounting notes REV24RF.. and RCR10/868

1 Placement of units

1.1 REV24RF.. and RCR10/868

• The units must be placed such that transmitted and received signals will be disturbed as little as possible. For this reason, the following points must be observed with both the REV24RF.. and RCR10/868:
• Do not mount the units on metal surfaces
• Do not mount the units near electrical wires or electronic equipment such as PCs, TV sets, microwave equipment, etc.
• Do not mount the units in the vicinity of large metal structures or other construction elements with fine metal meshes like special glass or special concrete
• The distance between controller / transmitter and receiver must not exceed 20 m or 2 floors

1.2 REV24RF.. (controller / transmitter)

• The controller / transmitter should be mounted in the main living room (wall mounting according to Fig. C, free standing according to Fig. E with stand)
• The REV24RF.. must be located such that it can acquire the room temperature as accurately as possible, without getting affected by direct solar radiation or other heat or refrigeration sources Wall mounting:

1.3 RCR10/868 (receiver)

• The receiver and switching unit should preferably be mounted near the actuating device
• Make certain that the mounting location is dry and protected from splash water
• The unit can be fitted to most commercially available recessed conduit boxes or directly on the wall

2 Checking the wiring

For electrical connections, refer to "Connection diagram".

Note: Do not use stranded wires, only solid wires or stranded wires with ferrules!

3 Notes

• The local regulations for electrical installations must be complied with
- If the reference room is equipped with thermostatic radiator valves, they must be set to their fully open position
• External preliminary protection with max. C 16 A circuit breaker is required in all cases
- If you wish to check the radio link, press the TEST button at the rear of the REV24RF..
- LED_1 is lit red if the RCR10/868 receives very weak or corrupted control telegrams, or no control telegrams at all for about 65 minutes. In this case, check the display of the REV24RF.. to see if there is an error message
- As long as the RCR10/868 receives control telegrams, the receiver works normally. If a control telegram is not correctly received, the relay will maintain the position assumed last. As soon as the RCR10/868 receives another correct control telegram from the REV24RF..., the receiver continues to work normally
- If, for 60 minutes, the RCR10/868 receives no control telegram, or no correct control telegram, the relay will be deenergized. Hence, the controlled device is switched off. LED_1 is lit red. As soon as the RCR10/868 receives another correct control telegram from the REV24RF., the receiver continues to work normally
• In the event of a power failure at the RCR10/868, the relay is switched OFF
- Should the REV24RF.. become faulty, the relay of the RCR10/868 can be controlled manually. As soon as the REV24RF.. resumes correct operation, its control telegrams will overwrite the relay's manual control. This process can take up to 130 minutes
- Press override button ⏻ to manually energize and deenergize the relay. LED_1 indicates manual control by blinking at high frequency. LED_2 is lit when Lx-L1 is closed (Lx-L2 open). LED_2 is dark when Lx-L1 is open (Lx-L2 closed)

Commissioning RF set

1 Switching on the REV24RF..

- Remove the black battery transit tab (Fig. F); as soon as the tab is removed, the unit is ready to operate

2 Selecting the language

- When starting up, the display shows the type of controller at top left and "THANK YOU ..." in all available languages on the text line

- Press one of the buttons to stop the running display. The choice of languages starts with "ENGLISH" (factory setting). Press + or - until the language you require appears. Press move the slider to confirm the selected language (also refer to Fig. G)

3 Mounting the RCR10/868 temporarily

- If possible, mount the receiver temporarily (e.g. using double-sided adhesive tape), thus allowing you to find the location with the best reception conditions

- Wire completely the RCR10/868. For steps to be followed, refer to Figs. H through M (close the front also)

4 RCR10/868 and REV24RF..

• The units are supplied interconnected
- For manual connection, refer to operating instructions

5 Mounting and setting up the REV24RF..

• Refer to "Mounting instructions REV24RF.. and RCR10/868"
- Mount or set up the REV24RF.. at your preferred location: Remove the unit from its baseplate; for procedure, refer to Fig. A - For wall mounting, refer to Figs. B, C and D - For setting up, refer to Fig. E

6 Finding the best place for reception

a) Switch on the RCR10/868
b) Set up the REV24RF.. at your preferred location. Test the radio link by pressing the TEST button at the rear of the controller (refer to Fig. N1)
c) The display of the REV24RF... shows the quality of the radio link. The longer the bar below the numbers 0...9, the better the quality of the radio link. If the bar only appears below number 0, there is no secure radio link (refer to operating instructions)

d) On the receiver, LED_1 indicates the quality of the radio link (refer to Fig. N2):

$$ \begin{array}{l} \text { Red } = \text { insufficient or no connection } \ \text { Orange } = \text { good } \ \text { Green } = \text { very good } \ \end{array} $$

e) If the quality of the radio link is insufficient, reduce the distance between controller and receiver. Then, repeat the test

7 Mounting the RCR10/868 in its final place

a) Switch power off
b) Mark the place where the RCR10/868 is located
c) If necessary, remove wiring
d) Mount the receiver at the place previously identified (refer to H through M), complete wiring and close the housing Figs.
e) Switch power on

With the radio clock active, the time change is shifted by the value set under code 30 (time zone).
Note 3: If the radio clock is not active or not present, the time change always takes place at 03:00 on the Sunday before the set date.
With the radio clock active, the time change is shifted by the value set under code 30 (time zone).

3 Function check

a) Check the display. If there is no display, check the batteries
b) "Continuously Comfort mode" read the temperature displayed
c) REV.. in heating mode: Set the temperature setpoint to a level above the displayed room temperature (see operating instructions). REV.. in cooling mode: Set the temperature setpoint to a level below the displayed room temperature (see operating instructions).
d) The relay and thus the actuating device must respond within 1 minute. Symbol ▲ appears on the display. If not:

• Check actuating device and wiring
- In heating mode, the room temperature is possibly higher than the adjusted temperature setpoint, in cooling mode possibly lower

e) Set temperature setpoint of "Continuously Comfort mode" to the required level

f) Select the required operating mode

4 Reset

User-defined settings:

Press simultaneously ○, + and - for 3 seconds:

All temperature and time settings of the slider positions are reset to their default values (refer to section "Factory settings" in the operating instructions). The settings made on the expert level will remain unchanged.

The clock starts at 12:00, the date on 01-01-08

(01 - January - 2008). During the reset time, all sectors of the display are illuminated and can thus be checked.

All user-defined settings plus those made on the expert level:

Press simultaneously the DIP switch reset button, + and - for 5 seconds:

After this reset, all factory settings will be reloaded. This applies to both the slider settings and the settings made on the expert level.
