A OTE
The time clock is provided with 96 switches, called riders, each of which covers a time
interval of 15 minutes (four per hour).
When a rider is switched from the inside (off setting) to the outside of the 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.
UT011Ap
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 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 by the user is active.
