The clock is provided with a selector

switch with three positions (see figure):

position, the clock

circuit is always

request of the room thermostat (if

installed) or the heating thermostat;

2.

Position “O”

HEATING OFF: in

this position, the

clock circuit is always

open (switch off) and

the boiler will

therefore never ignite

for heating;

3.

“Central” Position

PROGRAMMING

ACTIVE: in this

position, the

programming set
