Installation - Fantini Cosmi O62C Manual

5 INSTALLATION

The programmable thermostat is installed on all the valves with thermostatic
option of the H series, with connection M30x1,5 as shown below:
1
Tighten the ring nut B (supplied) on the radiator valve A;
2
Insert the programmable thermostat C on the ring nut B you will
hear a "click" when the two elements are correctly coupled.
The programmable thermostat must be in "INST" or "ON" mode in order
to fix it to the ring nut without too much effort. If the programmable
thermostat is installed at a later time, select the "INST" menu
before fixing it to the ring nut. To ensure better temperature adjustment, you are advised to install
the programmable thermostat with the display facing upwards. IMPORTANT: if you hold onto the
programmable thermostat when screwing the ring nut onto - or unscrewing it from - the valve, this will
cause irreversible damage to the mechanism and the coupling teeth of the ring nut itself.
6 REMOVING THE PROGRAMMABLE THERMOSTAT
1
Set the maximum temperature via the wheel selector (the display
will show "ON") and wait at least one minute.
2
Press in the point indicated by the arrow (A) to release the
programmable thermostat from the ring nut.
7 VALVE ADAPTATION PROCEDURE
At the initial start-up, press the OK key several times (skipping the clock/calendar setting operation)
until the word ADAP appears on the display.
O62C performs a self-calibration, checking the valve limit switches. This procedure may take a few
minutes, after which O62C resumes normal operation.
An additional adaptation procedure may be needed if the radiator does not fully cool down when the
programmable thermostat is OFF. If the procedure concludes with error E2, check the correct coupling
with the valve and take the batteries out for a few minutes, then replace them and perform a new valve
adaptation procedure.
