For values:

• above -60dB: excellent signal quality
• between -60dB and -90dB: good signal quality
• below -90dB: poor signal quality that could compromise the communication between the device and the access point. In this case, move the device closer to the access point

This screen also shows:

- the status of the Wi-Fi connection:

steady on: device connected to the home network
flashing: Wi-Fi network search in progress or test finished

Note: the icon 🔔 is always flashing during the first 20 seconds or so when this screen is displayed.

- the device's MAC address.

It is a sequence of characters that uniquely identifies a device within a network, the reading must be done by scrolling through the 3 dedicated pages (in the example: 42-F5-20-1E-F8-20).

Minimum/Maximum settable temperature

Under particular installation conditions, for example in public buildings, hotels, etc., it may be useful to limit the range of values that the temperatures T1 / T2 / T3 and Tm can assume, in order to prevent incorrect settings by the user.

- LO is the lower limit

Allowed values: 2^irc C ÷ H Factory value: 2^irc C

- H is the upper limit

Allowed values: L₀ ÷ 50^ircC Factory value: 50^ircC

Password for keylock

It's possible to set a keylock if the chronothermostat is installed in public places or if you want to prevent anyone from modifying the operation parameters.

To set a password, enter on field PR5 a value between 001 and 999. To deactivate the password press the key ▼ until “--” appears.

When the keyboard is locked, the chronothermostat performs all its functions using the set regulation parameters.

If the keypad lock is active and any key is pressed, appears on the display for a while according to the inscription bLOC.

To unlock the device, hold down any key until the flashing dashes appear: enter the password to unlock the keyboard, which will remain unlocked for 30 seconds from the last press.

Note: if the password has been forgotten, to unlock the device it is necessary to remove and restore power to the device. When switched on again, the keyboard remains unlocked for 30 seconds, which is sufficient time to access the appropriate menu and consult / deactivate the password.

System operation hours

This page shows the total number of hours of operation of the system (relay ON) for the current mode (identified by the icons 🙏 or 📞)

The hour counter has 5 digits and can be reset by holding down the 🔒 key for a long time until 00000 appears.

NOTE: The maximum storable value is 65535 hours (approximately 7 years).

This data is stored in non-volatile memory (it is not reset when the device is reset)

MANUAL OPERATION

During manual operation the device performs as a normal thermostat, adjusting on the basis of the Tm temperature (manual setpoint), independently from the day and the time where it is.

The manual operation is signalled with the switch on of the symbol 📋 in the field (6).

To move from automatic operation to manual operation:

1. Press the 🖱 key twice. In the field (8) the setpoint (Tm) currently set flashes
2. set the desired setpoint with the keys ▲ and ▼ and confirm with the key
3. at this point on field (8) the value of the environment temperature reappears and the instrument operates in manual.

If you want to change the setpoint (Tm) press the key 🏠 and repeat the points 2 and 3.

To go back to the automatic operation press for a long time the key (3 seconds about).

OFF OPERATION

In off mode the device doesn't perform any regulation (*) but it continues to display the day, the time and the measured temperature.

(*) In the case of heating/winter operation the device still maintains a minimum temperature - Toff antifreeze temperature - to avoid the freezing of the system and of the environment where the device is installed.

Toff can have values between 1^irc C and 50^irc C or it can be completely excluded; in this last case the maintenance of minimum temperature is not guaranteed.

The default Toff is 6°C but it's possible to modify this value by accessing the ADV menu (see "Antifreeze temperature" on page 35).

To switch the device off press the key ▼ until the symbol ⏻ displayed (field (9)).

To reactivate the regulation, returning to the operating (automatic or manual) preceding the switching off, press the key ▼ for about 3 seconds.

BACKLIGHTING MANAGEMENT

The chronothermostat have a backlit LED display that is normally on.

If the installation makes it appropriate (for example in bedrooms), the backlight can be turned off. In this condition, the chronothermostat continues to operate normally and the backlight turns on only when the programming menu is entered.

It's possible to turn off the backlighting by pressing the key ▲ for 3 seconds.

To reactivate the backlighting press the key 📂 or at least 3 seconds.

MINIMUM AND MAXIMUM VALUES

It's possible to display the measured values of minimum and maximum temperature. To display these values press the key ▲ (maximum value H) or ▼ (minimum value L0).

During the display it is possible to reset these values by holding down the (maximum value H I) or or ▼(minimum value L D) key until 2 dashes appear instead of the temperature.

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 based on the type of configuration set:

• with remote control configuration, the change of summer / winter time (and synchronization of the date / time) occurs automatically through the WiFi connection.
• with configuration without remote control, the summer / winter time change is managed automatically by the device, increasing by one hour if you switch from solar time to summer time and decreasing by one hour if you switch from summer time to winter time. The device is factory configured to switch to daylight saving time on the last Sunday in March at 02:00 to return to solar time on the last Sunday in October at 03:00, in accordance with what happens in Europe. It is possible to disable the automatic change of summer / winter time or modify the set parameters.

To change settings:

1. Access the menu of time and date change, pressing for a long time the key SET until the symbol 🤨 starts flashing.
2. Press the key 🖼 to access the time and date modification. At this point, during the modification of any parameter (seconds, minutes, hour, year, month or day) press for a long time the key 🖼 until the display shows the writing RUCO on field (3)

1. Choose with the keys ▲ and ▼ the automatic time change activation (AUTO On) or the deactivation (AUTO OFF) and confirm with the key

2. If OFF you go back to the date/time change; if On the current setting for the passage to summer time is displayed (indicated with the symbol 🌐). In the example:

a. the Sunday (7) of the last week (LR) of March (03) at 2 o'clock (02) b. if it's necessary change the parameters with the keys ▲ and ▼ and move to the next parameter with the key ▼ The sequence requires the insertion of:

i. day (1...7) of the week ii. the week of the month (first, second, third, fourth, last - LR) iii. the month (1...12)

iv. the hour

1. Press the key ↓ the current setting for the passage to the winter time is displayed (indicated with the symbol 🔍). In the example: a. the Sunday (7) of the last week (LR) of October (10) at 3 o'clock (03) b. if it's necessary change the parameters with the keys ▲ and ▼ and move to the next parameter with the key 🔍. The sequence requires the insertion of:

i. day (1...7) of the week ii. the week of the month (first, second, third, fourth, last - LR) iii. the month (1...12) iv. the hour

1. Once all parameters are set, to exit and go back to the programming menu, press for a short time the key SET. To exit and go back to the normal operation press for a long time the key SET or wait for the time-out expiration (30 seconds about).

REGULATION TYPE

The chronothermostat have two types of regulation:

On/off regulation

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

graph LR
    A["relay ON"] --> B["SET-DIFF SET"]
    C["relay OFF"] --> B
    D["Temperature increasing"] --> E["Relay ON"]
    F["Temperature increasing"] --> G["Relay OFF"]
    H["Relay ON"] --> I["SET+DIFFSET"]
    J["Relay OFF"] --> I
    K["Temperature increasing"] --> L["Relay ON"]
    M["Temperature increasing"] --> N["Relay OFF"]

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

Proportional regulation (heating only)

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 within whom to perform the proportional regulation. The band is centered on the setpoint and it can have values between 0.5^irc C and 5^irc C; outside these values the heating will be always on (if setpoint-band > environment temperature) or always off (if setpoint + band < measured temperature).
• 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 device 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 differential 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, the differential value (on/off regulation), band and period (proportional regulation) see chapter “Regulation parameters” on page 35.

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 fi eld (8).

TIMINGS: WHAT THEY ARE

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

The timed operations are the following:

Timed automatic

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

Timed manual

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

Timed off

If you set a timing in off status, this off status will be maintained until the end of the timing, will then switched to the operation that preceded 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 (modifi cation of the summer time change included)
• manual modification of the operating mode
• change of the operating logic from winter to summer (or viceversa)

To set a timing, see chapter "Timing setting" on page 32.

WINTER PRESET PROGRAMS

Perform a reset to delete the settings entered and restore the device to the factory values (excluding the network settings for remote control which can be changed as described on pages 18-19).

To reset:

1. from the home screen, press and hold the SET key to access the menu configuration. 📋 flashes.
2. keep the ▲ and ▼ keys pressed at the same time until the display shows “ rES”.
