Operation and display General function
This electronic thermostat for radiators can be used to control
room temperature on the basis of time. The actuator moves a
valve, thereby allowing the amount of heat flowing to the heating
appliance to be controlled. The controller is compatible with all
standard heating appliance valves. The large illuminated display
ensures user-friendly operation. A wireless receiver allows the
device to receive commands from taught-in system components.
Installation can be achieved in 3 easy steps.
Step 1: Inserting (replacing) the batteries
Remove the battery compartment cover.•
Insert 2 new LR6 batteries (Mignon/AA)•
into the side battery compartments, en-
suring they are the right way round.
Reattach the battery compartment cover•
and click into place.
New alkaline batteries have a life of ap-
proximately two years. A battery symbol
() will indicate when the batteries
need to be replaced. After removing the
old batteries, please wait approximately 1 minute before
inserting the new ones. This device does not support op-
eration with rechargeable batteries.
Never recharge standard batteries.
Doing so will present a risk of explosion.
Do not throw the batteries into a fire.
Do not short-circuit batteries.
Used batteries should not be disposed of with
regular domestic waste. Instead, they
should be taken to your local battery dis-
posal point.
Step 2: Setting the date and time of day
The firmware version number will be displayed briefly once
you have inserted/replaced the batteries and then you will be
automatically prompted to set the date and time of day.
Use the setting wheel (C) to set the year (B).•
Confirm with OK (D).•
Use the setting wheel (C) to set the month (B).•

Confirm with OK (D).•
Use the setting wheel (C) to set the minute (A).•
Confirm with OK (D).•
The motor will start moving back the control pin while the
entries are still being made.
If “InS” is displayed with a rotating “•
∏ ” symbol, this
indicates that the motor is still moving back. Once the
device is ready for the actuator to be installed on the
valve, just “InS” will appear on the display.
The weekly program and other settings can be cus-•
tomisedprior toinstallation.To do this, press the menu
button when “InS” is shown on the display. For further
details, please see “4. Configuration menu”.
Once programming is complete, “InS” will reappear on•
the display and installation (Step 3) can commence.
When “InS” is visible on the display, you can activate
the teach-in function prior to installation by pressing
the
button briefly.
Step 3: Installing the electronic thermostat
The actuator can be installed on all standard heating
valves. There is no need to drain away water or fiddle
around with the heating system before doing this. First,
you need to remove the old thermostat dial:
Turn the thermostat dial anti-•
clockwise as far as it will go (A).
Release the thermal ring of the•
thermostat (B).
Remove the thermostat from•
the valve (C).
An adapter will need to be used in the
case of certain valves. Adapters for Dan-
foss valves (RA, RAV, RAVL) are included in the scope of delivery. For
details, please refer to the adapter overview (see 20).
The adapter must be placed on the valve and turned until•
it is securely seated.
In the case of the RAV adapter, the•
extension supplied must be at-
tached to the valve tappet.
The RA and RAV adapters must, in•
addition, be secured by means of
the bolt and nut supplied.
The electronic thermostat can only
be installed if “InS” is showing on the
display. Following installation, the actuator will perform an
adjustment run so that it can adapt to the valve. During
this process, “AdA” will be displayed.
Place the actuator on the valve.•
Tighten the union nut.•
“InS” will appear on the display, press the OK button.•
The actuator will perform an adjustment run (“AdA” will•
appear on the display, operation not possible).
After that, the actuator will be ready for operation (Auto mode).•
If the adjustment run was initiated prior to installa-
tion, or if an error message will be displayed (F1, F2,
F3); press OK to move the motor back to the “InS”
position.
1. Setting the weekly program
The weekly program allows you to set up to 3 separate
heating periods (7 switching times) for each day of the
week. Programming is performed in relation to the se-
lected days, for which temperatures must be stored for a
period from 00:00 to 23:59.
Press and hold down the menu button for more than•
3 seconds.
“Pro” will appear on the display.•
Confirm with OK.•
“dAy” will appear on the display.•
The setting wheel can be used
to select an individual day of the
week , a l l wo r k i ng da y s, th e w e ek-
end or the entire week (example
shows working days selected).
Confirm with OK.•
Use the setting wheel to set the first time segment (exam-•
ple shows 0:00 to 6:00).
Confirm with OK.•
Then, select the required temperature for the selected time•
segment (example shows 17.0°C).
Confirm with OK.•
Keep repeating this process until you have finished storing•
temperatures for the period from 0:00 to 23:59.
In Auto mode, the temperature can be modified at any time
via the setting wheel. The modified temperature will then
be retained until the next program changeover.
2. Weekly program: Examples
Th e ele ctr oni c the rmo stat a llow s you to s to re up to 3 he at-
ing periods (7 switching times) with individual tempera-
ture settings for each day of the week. The factory set-
ting consists of two heating phases (from 6:00 until 9:00
and from 17:00 until 23:00 respectively) for every single
day of the week:
From 00:00 to 06:00 17.0°C
From 06:00 to 09:00 21.0°C
From 09:00 to 17:00 17.0°C
From 17:00 to 23:00 21.0°C
From 23:00 to 23:59 17.0°C
To represent the switching periods, the display shows
bars for every other switching interval. In this exam-
ple, no bars are shown for the interval from 0:00 to
6:00. Bars are only shown on the display for the in-
tervals from 6:00 to 9:00 and from 17:00 to 23:00.
If a room also needs to be heated at around noon, the cor-
responding program might look like this:
Monday to Sunday
From 00:00 to 06:00 16.0°C
From 06:00 to 09:00 22.0°C
From 09:00 to 12:00 17.0°C

18. Instructions for disposal
Do not dispose of the device with regular
domestic waste.
Electronic equipment must be disposed of at local
collection points for waste electronic equipment in
compliance with local directives governing waste
electrical and electronic equipment.
The CE sign is a free trade sign addressed ex-
clusively to the authorities and does not warrant

21. Information about radio operation
Radio transmission is performed on a non-exclusive trans-
mission path, which means that there is a possibility of
interference occurring.
Switch ing oper ations, ele ctr ic mo to rs or fault y elect ric d e-
vices are some of the reasons why interference may oc-
cur. The range of transmission within buildings can deviate
greatly from open air distances. Besides the transmitting
power and the reception characteristics of the receiver,
environmental infl uen ces su ch as humidit y and loc al struc -
tures also play an important role.
ELV Elektronik AG hereby declares that this device con-
forms with the essential requirements and other relevant
regulations of Directive 1999/5/EC.
