6. TIME CLOCK

UT014A

ECHNICAL

ATA

Ambient

temperature:

- 10°C to + 55°C

Shortest

switching time: 15 minutes

Programmable: Every 15 minutes

: the time clock is for Central Heating control only.

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;

UT011Ap

- 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 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 programme set by

the user is active.
