OPERATING YOUR THERMOSTAT (CONTINUED)

I’m planning to go out for the weekend. I would like to save energy when I

am away but I would like to be sure that my house would be at comfortable

temperature on Sunday at 17:00.

1. Follow the same procedure as described above to select number of days you

will be away.

2. Press the

(HOLIDAY) button a second time to display the holiday return

time. (The time displayed is current time + 1 hour rounded off to 30 minutes)

The return time can be adjusted using the

+ or – button in 30 minutes steps.

3. At the programmed return time the thermostat will return to the normal control

as set by the slider position.

I’m having some friends round for party. How can I extend my heating

program for a few hours?

1. Press the

(HOLIDAY) button twice to display the time when you would like to

switch the heating off. (The time displayed is current time + 1 hour rounded off

to 30 minutes) The return time can be adjusted using the

+ or – button in 30

minutes steps.

2. Adjust your room temperature using TEMPerature

or button

3. The thermostat will maintain the set temperature level until specified time. At

the programmed time it will return to the normal control as set by the slider

position.

How can I restore the factory program setting?

The factory program is restored when the RESET key located at the back of the

thermostat is pressed.

NOTE: Before removing the thermostat from the wall review the section

“MAINTAINING YOUR THERMOSTAT”

MAINTAINING YOUR THERMOSTAT

Chronotherm Modulation is made from high quality plastics and does not require

special maintenance if used under normal operational conditions.

In case you have to remove your thermostat temporarily for purpose of wall

decoration or alterations follow the guidelines below.

Remove the thermostat from the wall plate

1. Switch off the electrical supply of the thermostat by isolating the heating

system.

2. Remove the thermostat by pressing the plastic lid with a screwdriver and gently

pushing it up. This will loosen the thermostat from its wall plate

3. Always protect the contacts in the wall plate from paint or other substances

TROUBLE - SHOOTING GUIDE

Chronotherm Modulation is able to provide you with fault diagnostic information.

Please note that the type of data sent from the boiler determines the way the

boiler faults are displayed. Review the boiler user manual for more information.
