Electronic thermostat
ETH eco
Operation and display General function
This electronic thermostat for radiators can be used to
control room temperature on the basis of time. The actu-
ator 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.
Installation can be achieved in 3 easy steps.
Step 1: Inserting (replacing) the batteries
Remove the battery com-•
partment cover.
Insert 2 new Mignon bat-•
teries (LR6/AA) into the
battery compartment, en-
suring they are the right
way round.
Reattach the battery com-•
partment cover and click
into place.
New alkaline batteries have a life of approximately three
years. A battery symbol ( ) will indicate when the bat-
teries need to be replaced. After removing the old batter-
ies, please wait appro-ximately 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
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.

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 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 Danfoss valves (RA, RAV, RAVL) are inclu-
ded 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 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 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.

appear on the display as end time.
Confirm with OK.•
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
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
