clock border (on setting), the circuit is
closed (switch on) for a period of 15
minutes and then the boiler starts if the
room thermostat (if installed) or the
heating thermostat require heat
(heating function on).
EXAMPLE
To set the heating of your home in
the time interval from 7.00 am to
9.30 am and from 7.00 pm to 10.00
pm every day:
- rotate the outer ring of the clock in a
clockwise direction until the correct
time of day (24h) lines up with the
arrow on the clock (at approx. 2
o’clock position);
- under no circumstances should the
minute hand be moved manually;
- make sure all the switches, i.e. the
riders, are placed on the inside of the
clock border;
- pull outward the riders for 7.00 am
and 9.30 am, and then all riders
between these two;
- repeat this for 7.00 pm and 10.00
pm.
Other heating intervals may be set in
the same way.
The timer has approximately 150
hours of battery back up for power
failure.
The clock is provided with a selector
switch with three positions (see figure):
1. Position “I” CONSTANT: in this
position, the clock
circuit is always
closed (switch on),
therefore the boiler
will constantly be
on and will only
shut off upon the
16
UT014A
