General function
This electronic thermostat for radiators can be used to con-
trol 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 opera-
tion. A wireless receiver allows the device to receive com-
mands 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 battery compartment, ensuring
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 batter-
ies need to be replaced. After removing the old batteries,
please wait approximately 1 minute before inserting the
new ones. This device does not support operation 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.

Operation and display
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 day (B).
Confirm with OK (D).
•
Use the setting wheel (C)
•
to set the hour (A).
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 indi-
•
cates 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-
•
tomised prior to installation. 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 activa-
te the teach-in function prior to installation by pres-
sing 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 ther-
mostat 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. Adapt-
ers for Danfoss 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 attached to the valve tappet.
The RA and RAV adapters must, in addition, be se-
•
cured 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 selected
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 sec-
onds.
“Pro” will appear on the dis-
•
play.
Confirm with OK.
•
“dAy” will appear on the display. The setting wheel can be
•
used to select an individual day of the week, all working
days, the weekend or the entire week (example shows
working days selected).
Confirm with OK.
•
Use the setting wheel to set the first time segment (ex-
•
ample 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 stor-
•
ing 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
The electronic thermostat allows you to store up to 3 heat-
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
From 12:00 to 14:00 20.0°C
From 14:00 to 17:30 17.0°C
From 17:30 to 23:30 21.0°C
From 23:30 to 23:59 16.0°C
If you have a home office and only want it to be heated
during the day on working days, you can program the fol-
lowing times:
Monday to Friday
From 00:00 to 08:30 17.0°C
From 08:30 to 17:00 21.0°C
From 17:00 to 23:59 17.0°C
Saturday and Sunday
From 00:00 to 23:59 15.0°C
