6. TIME CLOCK

NOTE: the time clock is for central

heating control only.

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
