Operation and display General function
This energy-saving controller 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 appli-
ance valves. The large illuminated display ensures user-
friendly operation.
Installation can be achieved in 3 easy steps.
Step 1: Inserting (replacing) the batteries
Remove the battery compartment cover.•
Insert 2 new Mignon batteries (LR6/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 three 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.
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
disposal 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 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
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”.

display and installation (Step 3) can commence.
Step 3: Installing the energy-saving controller
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 c er tain valve s. Adapt-
ers for Danfoss valves (RA, RAV,
RAVL) are included in the scope of delivery. For details,
please refer to the adapter overview (see 18).
The adapter must be placed on the valve•
and turned until it is secure-
ly seated.
In the case of the RAV adapter,•
the extension supplied must be
attached to the valve tappet.
The RA and RAV adapters must,•
inaddition,be securedbymeans
of the bolt and nut supplied.
The energy-saving controller can
only be installed if “InS” is show-
ing 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, 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 (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
The energy-saving controller allows you to store up to 3
heating periods (7 switching times) with individual temper-
ature 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
