Sond ă extern ă (op Ġ ional)
Conecta Ġ i sonda la bornele corespunz ă toare. Lungimea maxim ă permis ă a cablului electric de conectare central ă – son-
d ă extern ă este de 50 m. Poate fi utilizat un cablu obi ú nuit cu 2 conductoare. Sonda extern ă trebuie instalat ă de preferat
pe peretele dinspre nord, nord-vest, sau pe cel pe care se afl ă majoritatea înc ă perilor principale în care sta Ġ i. Sonda nu

cesar, trebuie protejat ă . În orice caz, sonda nu trebuie s ă fie montat ă lâng ă ferestre, u ú i, deschideri de aerisire, hornuri
sau surse de c ă ldur ă care ar putea afecta citirea temperaturii.

CAUTION: The room thermostat must have clean contacts. CONNECTING 230 V.
TO THE TERMINALS OF THE ROOM THERMOSTAT WILL IRREPARABLY DA-
MAGE THE ELECTRONIC CARD.
When connecting a remote timer control or a timer switch, do not take the power
supply for these devices from their cut-out contacts. Their power supply must be
taken with a direct connection from the mains or with batteries, depending on the
kind of device.
External probe (optional)
Connect the probe to the respective terminals. The maximum permissible length of the electric cable connecting the
boiler - external probe is 50 m. A common 2-wire cable can be used. The external probe should preferably be installed
on the North, North-West wall or on the wall facing most of the main living-room. The probe must never be exposed to
the early morning sun, and in general (as far as possible) it should not be exposed to direct sunlight; protect it if neces-
sary. In any case, the probe must not be installed near windows, doors, vents, flues or heat sources that could affect
the reading.
