BACKLIGHTING MANAGEMENT

The chronothermostats of the Iride series have got a backlit display with led. There are
some differences between battery powered models and mains powered models.

Battery Iride

The battery powered model has got a backlighting of blue colour, which is activated
only if they are inside any menu of programming or if any key is pressed. In normal
operating status the backlight results off.
This behaviour is not modifiable.

Iride 230V~

The 230 V model has got a multicolor backlighting which can be configured according
to the preferences’ user.

The possible configurations for the backlighting are the following:

• RGB (RGB) in this case the backlighting changes following the difference

between the measured temperature and the programmed setpoint. In
particular, it will be

- blue, if the measured temperature is lower than the programmed setpoint
of at least 0.5°C (or we are inside any programming menu)

- green, if the difference between the measured temperature and the setpoint
is, in absolute value, lower than 0.5°C (or if the device is in off mode)

- red, if the measured temperature is higher than the setpoint of at least

0.5°C (or in case of probe error)

• BLUE (BLU) in this case the backlighting will be blue fixed

• GREEN (GRE), in this case the backlighting will be green fixed (blue inside

programming menu)

• RED (RED), in this case the backlighting will be red fixed (blue inside

programming menu)

• OFF (0FF), in this case the backlighting is always off (blue inside

programming menu). Useful for example in bedrooms.

It’s possible to configurate the backlighting pressing the key

SUMMER TIME CHANGE

Summer time is the convention to step up of one hour the dials of the clocks during the
summer period in order to prolong the lighting time in the late afternoon to the loss of the
early morning.
In European countries summer time starts the last Sunday of march and ends the last
Sunday of october.

The chronothermostat manages the summer/winter time change as follows:

- increasing of one hour to move from winter time to summer time

- decreasing of one hour to move from summer time to winter time

The device is default configured to move from summer time the last Sunday of march at 2
o’clock to go back to winter time the last Sunday of October at 3 o’clock in accordance with
Europe convention.
However it’s possible to deactivate the automatic time change or to change the date or the
hour of the time change.

REGULATION TYPE

Iride has got two types of regulation:

On/off regulation

English

During on/off regulation the chronothermostat measures once a minute the
environment temperature and it carries out the regulation on the basis of the following
logic:

heating mode cooling mode

relay ON

relay OFF

Temperature
increasing

SET-DIFF SET

where SET represents the setpoint and DIFF the hysteresis (useful to avoid continuous
switches on/switches off dangerous for the system in proximity to the reaching of the
setpoint.

Proportional regulation (only in heating)

In heating mode, the on/off regulation is available and also the proportional regulation
which in some systems allows a more precise regulation to obtain a constant
temperature.

This regulation requires to specify two parameters:

• the band, which represents the temperature values with whom to perform the

proportional regulation. The band is centered on the setpoint and it can have values
between 0,5°C and 5°C; outside these values the heating will be
always on (if setpoint-band > environment temperature) or always off (if setpoint +
band < measured temperature).

relay ON

relay OFF

Temperature
increasing

or wait

SET+DIFFSET

• the regulation period which represents the duration of the regulation cycle

(activation time + deactivation time of heating) and it can have values of 10, 20 or
30 minutes.

During the operating, at the beginning of the regulation period, the instrument
measures the environment temperature and it compares it with the programmed
setpoint; on the basis of this difference the activation time is calculated (and
consequently the deactivation time). The more the measured temperature is next to the
setpoint value – band, the more the activation time will be predominant in comparison
with the deactivation time; on the contrary, the more the measured temperature is next
to the setpoint value + band, the more the deactivation time will be predominant in
comparison with the activation time).
Once regulation period is passed, the device compares again the environment
temperature with the setpoint and it updates the activation and deactivation times for
the new period.

The result of the proportional regulation is subordinated to the correct selection of the
parameters.

Select the value of the regulation type as follows:

• 10’ for low thermal inertia systems (fan-coil)

• 20’ for medium thermal inertia systems (aluminium radiators)

• 30’ for high thermal inertia systems (cast-iron radiators)

Select the regulation band value as follows:

• broad band (5°C) for systems with high thermal gradient

• narrow band (0.5°C) for systems with low thermal gradient

Attention: the device is default configured to operate in on/off with hysteresis
set at 0.3°C. This configuration is suitable for the most part of the situations
and for this reason it’s advisable to modify it only in particular situations.

To modify the regulation type, dIF value (on/off regulation), band and period
(proportional regulation) see chapter “Regulation parameters” at page 29.

Emergency regulation (winter mode only)

The device performs a regulation of emergency if an error occurs during the reading of
the probe or in case of time loss.

In case of probe error, if the antifreeze function is not excluded, the device activates
the load for 10 minutes every 4 hours. The display shows the writing Err on field (7).

In case of time loss (because of depleted batteries or blackout of a duration higher
than the charge reserve) the device restarts from the off mode, adjusting on the basis
of the antifreeze temperature, if it hasn’t been deactivated before. Reset date/ time
to go back to the normal operation (programs modifications and settings remain
memorized).

English

TIMINGS: WHAT THEY ARE

Timings allow to maintain the current operation (automatic, manual, off) for a certain
period (times or days) and once passed the chronothermostat changes the operating
mode, as explained below.

The timed operations are the following:

Timed automatic

If in automatic status you set a timing, such off status will be maintained until the end
of the timing operation, will then switched to off mode.

Timed manual

If in manual status you set a timing, such off status will be maintained until the end of
the timing; operation will then switched to automatic mode.

Iride Chronothermostat User Manual

Timed off

If in off status you set a timing, such off status will be maintained until the end of
the timing, operation will then switched to the one active before the deactivation
(automatic or manual).

If you set a timing, the display shows the symbol .

Attention: the timing is calculated in minutes and for this reason if for
example you set a timing of 3 days at 12:15 on Tuesday it will expire at 12:15
on Friday.

Attention: the timings can end before their programmed expiration if one of these
actions occur:

- time/ date modification (modification of the summer time change included)

- manual modification of the operating mode

- switching of digital input (only for battery models)

- change of the operating logic from winter to summer (or viceversa)

To set a timing, see chapter “Timing setting” at page 26.

DEVICE RESET

If you want to erase all performed settings and to recharge the default values, proceed
as follows:

1. to switch off and to switch on the power of the chronothermostat (230 V versions)

or to extract the chronothermostat from the wall-mounted base and reinsert it
(battery versions)

2. during the flashing of the keys press the key

dEF.

Default values are indicated on page 42 of this manual.

English

until the display shows the writing

BATTERY REPLACEMENT

The model Iride (batteries) signals the status of depleted batteries switching on the
symbol

(field (10)) and making the display to flash.

In this status the regulation is always guaranteed, but it’s advisable to replace the
batteries as soon as possible! (*)

If the charge level of batteries further decreases, the chronothermostat enters into less
consumption mode, it switches off the display and it doesn’t perform any regulation.

(*) Remove the depleted batteries and replace them with the new ones in a maximum
time of one minute (charge reserve) to avoid to lose the settings of date and time
(the performed programmings on the contrary remain memorized even if this limit is
surpassed).

Attention: after batteries replacement, the display will switch on within 15
seconds at max.



Dispose of the used batteries observing the
laws in force in relation to the disposal
of hazardous waste.

The removal of the device occurs
by pulling on the convexity of the frame
(see figure).
