5. Battery compartment
The radiator valve thermostat requires two 1.5 V AA alkaline batteries.
Other functions:
Anti-frost:
If the radiator valve thermostat detects the risk of frost, the valve opens automatically
and causes the temperature to rise.
Anti-calcification:
To prevent calcification, the valve opens and closes once a week Saturday night at 11
p.m. The display shows “CAL” during this process.
Installation of radiator valve thermostat V2
The radiator valve thermostat replaces the temperature control of the heater. To install
the thermostat, please proceed according to the following steps:
1. Unscrew the existing temperature control from the heater.
2. Check that the valve can be pressed in. Lubricate the valve in any case. Install the
fastening screw thread onto the heater valve and fasten it by rotating it clockwise. Do
not apply excessive force. The radiator valve thermostat is sufficiently fastened if it
does not rotate by itself anymore.

as flashes, the motor works.
4. Open the web interface of the alarm panel, go to the menu “Sensors” “Add”, and
press “Start”.

Boost/Learn button of the radiator valve thermostat for ten seconds.
6. The display of the radiator valve thermostat shows “888” briefly.
7. Press to add the radiator valve thermostat to the alarm panel.
8. You can now “stop” the learn mode of the alarm panel or continue to add additional
sensors.
