Note: in heating mode (winter), the device if off, it regulates according to the

antifreeze temperature Toff in order to prevent freezing of the system.

Toff can have values from 1 to 10° C or be excluded; in this case any minimum

temperature is guaranteed.

Replace the batteries as soon as

possible! Dispose of batteries

in the appropriate recycling

containers.

In this case the regulation is inhibited and the relay contacts

remain in position 2-3.

SAFETY WARNINGS

During product installation and operation it is necessary to observe the

following instructions:

1) 1) The device must be installed by a qualified person, in strict compliance with

the connection diagrams.

2) Do not power or connect the device if any part of it is damaged.

3) After installation, inaccessibility to the connection terminals without appropriate

tools must be guaranteed.

4) The device must be installed and activated in compliance with current electric

systems standards.

5) Before accessing the connection terminals, verify that the leads are not live.

6) In the electrical system of the building where the

device

must be installed, a

protection device from the overcurrents must be present (for KEO-A LCD only).

If the keypad lock is active, pressing one key appearsLoC

and the password is required. If it’s properly inserted the

keyboard is unlocked for the next 30 seconds.

To enter menu Advanced programming keep simultaneously pressed for 3 seconds the

keys and until will appear. PR

The items of the menu are displayed in succession. For each item is displayed an identi-

fication abbreviation and its relative blinking value. Use the

keys and to modify the value. The passage to the

next parameter occurs after 3 seconds without pressing

any key. Once all parameters are set the writing is END

displayed and the thermostat returns to normal operation

saving the effected modifications.

• Install the thermostat at a height of about 1.5 m above the floor, away from

direct sunlight, away from doors, windows, heat sources, locations with

excess or total lack of ventilation.

• Install the white or anthracite grey frame according to your preferences by

hooking it to the cogs of the device.

• Make the connections by respecting the diagrams described in this manual.

• Fix the device inside the 3 modules box in compliance with the assembly

diagrams described on the back of this instruction sheet. The accessories

for the installation included in the package allow the mounting of the plates

described in the diagram “adjustable plates” and they are:

- mount A

- mount B (it could be necessary to remove the side cogs)

- mount AIR

- couple of side BM plastic elements (both of white colour and grey colour)

- couple of side VI plastic elements (both of white colour and grey colour)

- frames of white colour and anthracite grey.

The Keo-B LCD has a configurable auxiliary input for the connection to

alternative to:

- an external temperature probe

- an external contact for reducing the set temperature.

With closed contact, the setpoint is reduced by 3 °C

than the set one and the symbol appears on the display.

To configure the auxiliary input, see “Advanced programming” in this manual.

• Keo-B LCD

The keo-B LCD has a backlighting of blue colour that is normally off and turns

on when you enter the menu: setpoint modification, advanced programming,

pin enter.

• Keo-A LCD

The Keo-A-LCD has a backlighting of blue colour which is on during normal

operation.

If the installation makes it necessary (for example bedrooms) you can turn off

the backlighting. In this condition the thermostat continues to operate normally

and the backlighting turns on when you enter setpoint modification menus,

advanced programming, pin enter.
