In the initial state, the batteries are already inserted. Simply remove the insulation
strip to activate the device.
To replace the batteries, please proceed as follows:
• Remove the battery compartment cover by pressing the battery
compartment cover on both sides with your fingers and remove
the cover by pushing it downwards.
• Insert 2 new 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.
The battery symbol (
) on the display indicates that the batteries need to be
replaced. After removing the empty batteries, wait approx. 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!
8. Set date and time
After inserting the batteries, the date and time is automatically requested after display
of the firmware version number and short motor run (“InS”).
• Set the year, month, day, hour and minute with the control wheel (
F) and confirm
by pressing the control wheel briefly.
You can adjust the time and date in the menu under “dAt”.
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 radiator thermostat can be installed
on the valve.
• The week program and date can be adjusted before installation. Press the Mode/
Menu button, while “InS” is shown in the display. You will find further information
in chapter “13. Setting the week program”.
• After the programming has been completed, “InS” is shown again in the display
and installation can take place.
9. Removal of the existing thermostat
The 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.
The snap-on fastening of the radiator thermostat can be used universally and with
the adapter VA80 for valves of the most popular manufacturers with a thread size of
M30 x 1.5 mm.
By means of the adapters supplied, the device can be installed on radiator valves of
type Danfoss RA, RAV and RAVL.
• Rotate the old thermostat dial to the maximum value (anti-clockwise). The
thermostat dial then no longer presses against the valve spigot, making it easier
to remove.
• Remove the thermostat head.
• If required, place one of the supplied adapters.
The adapting run starts afterwards (see sec. “11. Mounting and adapting run”).
10. Adapters for Danfoss valves
The provided adapters (RA, RAV and RAVL) can be used for installation on Danfoss
valves. The arrangement of the suitable adapter ring for the appropriate valve can be
found in the following figures.
The
RA and RAV adapters have been manufactured with pre-tension in order to
provide a better seat. Use a screwdriver during installation if necessary, and bend it
open slightly in the vicinity of the screw. After clipping onto the valve body, please
attach the adapter using the provided screw and nut.
The spigot extension (
I) must be fitted to the valve pin of RAV valves prior to installation.
The adapter RAVL does not have to be screwed. Fit the short spigot extension (
I)
on the valve pin before installation. You can simply break off the spigot extension
connected to the adapter.
The Danfoss valve bodies have elongated notches (
J) around their circumference,
which also ensure that the adapter is properly seated when it snaps on. During
installation, please ensure that the pins inside the adapter (
K) are lined up with
the notches (
J) on the valve. Ensure that the adapter is properly clipped on.
Take care during installation that you do not trap your fingers between the two
halves of the adapter!
