Function

Using the device for any purpose other than that de-

scribed in this operating manual does not fall within

the scope of intended use and shall invalidate any

warranty or liability. This also applies to any conver-

sion or modification work. The device is intended for

private use only.

3 function

The ETKF+Radiator Thermostat is responsible for regulat-

ing the radiators within the HERZ system. During ventila-

tion, the ETKF+Radiator Thermostat automatically reduces

the temperature in a room in order to save on energy costs.

Communication between the HERZ components is bidirec-

tional. This ensures that the information sent reaches the

recipient.

The configuration of the ETKF+Radiator Thermostat is made

according to the system variant used. You have the possibility

to choose between the following two variants:

HERZ Room solution

In the room solution, the settings of all connected de-

vices in your room can comfortably be made via the

Wall Thermostat+. Up to 8 ETKF+Radiator Thermo-

stats and 8 Window Sensors+can be connected and

controlled via the Wall Thermostat+.

Function

HERZ Radiator solution

With the HERZ Radiator solution you can easily start

using the HERZ system. The ambient temperature

within a room can be flexibly controlled and regulated

with up to 2 ETKF+Radiator Thermostats and 3 Win-

dow Sensors+. Configuration is performed directly on

the ETKF+Radiator Thermostat.

With a Wall Thermostat+the solution can be extended

to a room solution..

Start-up

4.1 diSplaY content in normal mode

Operating mode, week day, setpoint temperature, time, ra-

dio signal and switching time periods are displayed in nor-

mal mode. In the example, the ETKF+Radiator Thermostat

is in automatic mode (Auto) and the comfort temperature

() of 21.0°C is set. The weekday Tuesday (Tu) and the time

(19:07 h) are displayed. The antenna symbol ( ) indicates

that the connection to the taught-in components has been

established. The heating phases are displayed as bar charts.

The bars for the heating phases in the week program

will only be displayed if the saved temperature is

higher than the reduction temperature. Please see

section 10.1 for examples.

5 Start-up

5.1 inSerting (replacing) batterieS

To insert the batteries into the ETKF+Radiator Thermostat,

please proceed as follows:

Start-up

• Remove the battery compartment cover by pushing it

forwards.

• Insert 2 LR06/mignon/AA batteries in the battery compart-

ment, making sure they are the right way round.

• Reattach the battery compartment cover and latch it into

place.

After inserting batteries, the radiator thermostat has to be

mounted on the radiator (see sec. „5.3 Installation on the

radiator“ on page 10). The ETKF+Radiator Thermostat

starts an adapting run afterwards (see sec. „5.4 Adapting

run“ on page 12).

A battery symbol ( ) indicates that the batteries need to

be replaced. After removing the batteries, you should wait

approx. 1 minute before inserting the new ones.

The service life of new alkaline batteries is approxi-

mately two years.

This device does not support operation with recharge-

able batteries.

Never recharge standard batteries. Doing so will pre-

sent 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, take them to

your local battery disposal point.

Start-up

5.2 Set date and time

If batteries are inserted or replaced, the date and time is

automatically requested after a brief display of the firm-

ware version number:

• Set the year, month, day, hour and minute with the hand-

wheel and confirm with the Boost button. The motor

moves the control pin backwards during the setting of

date and time.

• If "InS" and the rotating activity symbol " " are displayed,

themotorstillreverses.Whenonly"InS" is showninthedis-

play, the radiator thermostat can be installed on the valve.

The ETKF+Radiator Thermostat+can be configured already

before installation. Press the auto/menu button for this,

while „INS“ is shown in the display (see sec. „10 Configura-

tion menu“ on page 19). After the programming has been

completed, „InS“ is shown again in the display and instal-

lation can take place.

5.3 inStallation on the radiator

The ETKF+Radiator Thermostat is easy to install and can

be done without draining heating water or intervening in the

heating system. No special tools are required, nor does the

heating have to be switched off.
