Adding a delay to a scheduled activation

This function is designed to delay an activation which is scheduled for a certain time.

You can, for example, to have a comfy temperature at 07:00 set up the sys-

tem to activate at 06:30. To obtain this, schedule your desired temperature for

06:00 and set a 30-minute delay; the device will activate the system at 06:30.

The set delay is shown on the display in the hour during which the delay is scheduled.

disabled.

Replacing the batteries

When this icon on the

display is flashing 󱊧 it

means the batteries need to

be replaced within a month.

Problem solving

Press the R reset button if there are any malfunctions.

This procedure restores the device to its factory settings.

Remote activations

By connecting a speciﬁc interface to terminals 1-2 (see "Electrical connections" on page 6)

you can remotely activate a pre-conﬁgured SCHEDULED MANUAL operating mode.

You can conﬁgure two SCHEDULED MANUAL modes, one for heating and one for cooling.

These programmable modes can be conﬁgured in the same way with which the SCHEDULED

MANUAL programs are conﬁgured (see "Using the SCHEDULED MANUAL setting" on page

11); by pressing this button at the end of the procedure, the program is saved in the

device's memory and activated only via telephone.

The program stays active until a dierent one is manually set on the device; when the

SCHEDULED MANUAL mode stops, the device reverts to working in the mode it was in before

it received the telephone message.

Note. When the program is remotely activated, the residual hour or day, is counted as a full

hour or as a full day.

placing the batteries is about

2 minutes; once that time

elapses the conﬁgured set-

tings will be restored to the

factory values.

Fit three new LR6 alka-

line AA 1.5V batteries, into

the battery housing while

respecting the polarities

shown on the bottom 󱊪.

ATTENTION: badly fitted

batteries may damage the

heating system.

careful with the small latch-

es. 󱊫.

If the instructions on the

display don't appear within
