• This product must only be used for the purpose for which it was designed. Any other

use is dangerous.

• The manufacturer declines all liability for any damage as a result of improper, incorrect

or unreasonable use.

• Risk of explosion if the batteries are replaced with others of the wrong type.

• Once the batteries are ﬂ at, do not treat them as unsorted general waste. Dispose of

them separately for recycling.

DISPOSAL - Dispose of the packaging material responsibly, in compliance with the

laws in force in the country in which the product is used.

Setting the type of heat management algorithm

The device lets you choose the type of algorithm to apply to manage the system: di er-

ential or proportional-integral.

Activating and conﬁ guring the di erential algorithm

This type of adjustment system

is recommended for systems

that are especially hard to control

due to extreme variations in the

outdoor temperature.

( ) , press the P but-

ton to access the section where

you can select one of the pro-

portional-integral programmes

available .

Use the buttons to select

the programme you want from

P1, P2, P3 and P4 (see graph

and table ); press the P button

to conﬁ rm your choice and ﬁ nish

programming.

If you have chosen programme P4, press the P button to access programming for the

individual parameters in programme P4 (manual).

Activating and conﬁ guring the proportional-integral algorithm

This algorithm allows the programmable thermostat to reduce the boiler ignition cycles

as the room temperature approaches the set temperature, thus considerably reducing

consumption while maintaining an optimal level of comfort.

There are three pre-set programmes available, suitable for di erent types of systems

(P1, P2 and P3), or a fully manual programme (P4).

The ﬁ rst parameter is the duration

of the ignition cycles .

Use buttons to choose the

cycle duration: 5, 10, 15, 20, 25,

30, 35 or 40 minutes .

Press button P to conﬁ rm the

set cycle time and proceed with

adjusting the minimum ON time.

Use buttons to choose the

minimum ON time between 1 and

5 minutes.

Press button P to confirm

the minimum ON time set and

proceed with adjusting the pro-

portional band.

Use buttons to adjust the

value of the proportional band to

between 1°C and 3°C.

The graph and table can be used to help decide on the programme type or parameter

values to be entered.

Press button P to exit programming mode.

Note. All parameters for conﬁ guring the type of thermal management algorithm are saved

in the device’s permanent memory.

Conﬁ guring auxiliary input operation (terminals 1-2)

Auxiliary input used for remote activation

By connecting a speciﬁ c interface to terminals 1-2 (see “Electrical connections” on page 6),

the COMFORT programme can be activated remotely for the relevant season.

Press button .

Use buttons to select the

function for the input:

= input enabled to activate

the COMFORT programme in heating

mode.

= input enabled to activate

the COMFORT programme in cooling

mode.

= input for remote activa-

tion disabled.

Press button to confirm pro-

gramming.

With (input for remote acti-

vation disabled), press button .

Note. To activate the set mode, close the contact and keep it closed (after approximately

5 seconds, the device will perform the action). To restore the previous condition, open

the contact and keep it open.

Auxiliary input used as window contact

By connecting a NO contact to terminals 1-2 (see “Electrical connections” on page 6),

you can ensure that when the contact is opened (generally applied to doors or windows),

boiler ignition is stopped until the contact is closed again.

Page 18 - Manual FA01433-EN - 03/2020 - © CAME S.p.A. - The contents of this manual may be changed, at any time, and without notice. - Translation of the original instructions

disable the window input.

= Input disabled.

= Input enabled.

Press button to conﬁ rm

programming.

If boiler ignition is cancelled be-

cause the input is open,

appears on the display.

Note. To switch off the thermal

zone, open the contact and keep it open (after approximately 5 seconds, the device will

perform the action). To restore the previous condition, close the contact and keep it closed.

Locking temperature level settings

To prevent the programmed levels

from being changed or the tem-

perature level from being changed

manually, press buttons P and

for three seconds.

Use buttons to enable/

disable the lock.

= Lock disabled.

= Lock enabled.

Press buttons P and to conﬁ rm

programming.

Resetting the device

Malfunctions or other technical issues

may require the unit to be reset.

Press button R .

This operation DOES NOT delete any

customised programming.

Restoring factory settings

To restore all factory settings, reset the device using the R button (see previous paragraph),

then (within 10 seconds) press buttons + + at the same time (if the reset is

successful, the version number of the device will show), before pressing the R button again.

Replacing the batteries

The ﬂ ashing icon on the display G indicates that the batteries will need to be replaced

within approx. 1 month. When appears on the display together with the symbol,

the unit is no longer in operation and the thermal zone is no longer being controlled.

Once the ﬂ at batteries have been removed, you have 2 minutes to insert the new batteries

(3 alkaline LR03 AAA 1.5V batteries); after this time, the device

is reset and the time setting is lost but the other existing settings are saved (any customised

programming etc.).

WARNING! Failure to replace the batteries promptly may cause damage to the heating system

(anti-freeze is no longer guaranteed).

Positioning the batteries incorrectly may damage the appliance.

The use of ﬂ at batteries may cause operating malfunctions.

System operating time

Press button C.

The operating time is displayed

for 5 seconds.

To reset the counter, press button

when the value is shown on

the display.
