Device Overview
Installation
Step 1: Inserting (replacing) the batteries
To insert the batteries into the energy saving thermostatic head ETKF+, please proceed as follows:
•
Remove the battery compartment cover by pushing it forwards
•
Insert two LR6/ mignon/ AA batteries in the battery compartment, 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. The radiator
thermostat starts an adaptating run afterwards.
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 approximately two years.
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, take
them to your local battery disposal point.
Step 2: Setting the date and time of day
If batteries are inserted or replaced, the date and time is automatically requested after a brief
display of the firmware version number:
•
Set the year, month, day, hour and minute with the handwheel 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, the motor still reverses. When only
"InS" is shown in the display, the energy saving thermostatic head ETKF+ can be installed on
the valve.
The ETKF+ can be configured already before installation. Press the Auto/ Menu button for this,
while „INS“ is shown in the display. After the programming has been completed, „InS“ is shown
again in the display and installation can take place.
Step 3: Installation of energy saving thermostatic head ETKF+
The ETKF+ 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. The
brass union nut M28 x 1,5 attached to the ETKF+ can be used with HERZ thermostatic valves and
