The Vacation function is used to switch the backup systems off and to allow cooling of the tank through
the solar panel when its temperature is below the tank temperature, for example: during the night.
During periods with low or no hot water consumption and high solar intensity, for example vacations,
extended holidays, or for the residence's off seasons, the tank will reach the maximum temperature limit
and the solar heating system will be subject to a high thermal load. Upon activating vacation mode, the
message [VAC,]is displayed, and this message is alternated with the display of the preferred
indication [,F01].
9.9 Functions lock
The use of the functions lock brings greater security to the operation of the instrument. When it is
actived, the setpoint and other parameters can be visible to the user when actived, but they are
protected against undue changes[,F41]= 2 or you can block changes to the control functions and
leave the adjustment of the setpoints enabled [,F41]=1.
Using the ; key (quick touch), access the function [LOC,] in the quick access menu, confirm by
pressing / (quick touch), then the message [no,,],will be displayed. Keep the>key pressed for
the time configured for the functions lock [tLOC], until [LOC,]is displayed. The message
[On,,]will be displayed indicating the functions lock is activated upon releasing the key.
To unlock, turn the controller off and then turn it on again with the > key pressed. Keep the key pressed
until [LOC,] is displayed. Keep the key pressed for 10 seconds and, upon releasing the key, the
message [OFF,] will be displayed indicating the functions lock is deactivated.
9.10 Control functions shutdown
Turning the control functions off allows for the controller to operate just as an indicator of temperature,
keeping the control outputs and the alarms disconnected. Use of this feature is enabled or not by the
control functions shutdown function [,f43].
When enabled, the control and alarms functions are turned off ([CTRL][OFF,]) or on
([Ctrl][ON,,]) through the quick access menu in the option [Ctrl]. When the control functions
are off the message [OFF,] will then be displayed alternately with the temperature and the other
messages. Except when [,f43] is equal to 3 or 4, in which case the display is switched off, keeping
only the icon on.
NOTE:It is also possible to switch the control functions on / off by pressing the ;key for five seconds.
9.11 Manually increase/decrease the time for daylight saving time
Using the option [Summ] on the quick access menu it is possible to increment or decrement one hour
to adjust the clock for daylight savings time.
When this function is accessed you need to enter the access code [,123]to allow you to make the
adjustment.
Use the<or> keys to choose between increase [Inc,] or decrease [dEc,]the time, and press
/to confirm.
9.12 Unit Selection (ºC / ºF)
To select the units that the system will use to operate, press <and> simultaneously as the
temperature/hour is being displayed, enter the option [Code] using the access code [,231] and
then press /. Then select the desired unit [,=C,]or[,=F,]using the<>keys and press/to
confirm.
NOTE: Whenever the units are changed, the functions' configuration assumes the factory default, so
they need to be configured again.

10. ADVANCED OPERATIONS
10.1 Access to the main menu
The main menu can be accessed through the quick access menu ( ;), option [Func] or by pressing
<and>simultaneously while the temperature is being displayed.
The following options will be displayed:
[Code] Entry to the access code
[Func] Change the advanced parameters
[ModE] Event schedule operation mode
[ProG] Event schedule programming
[ClO,] Adjustment or display of the date and time
Select the desired function using the keys. Press (quick touch) after selecting the function <or> /
to view its value. Use to change the value and press / when ready to save the configured <or>
value and return to the functions menu. To leave the menu and return to the normal operating mode
(temperature indication), hold down (long touch) until [----]appears./
Note: If the functions lock is active, the controller will show the message [LOC,], in the display upon
pressing and will not allow the adjustment of the parameters.<or>
10.2 Access Code
To change the parameters or adjust the clock, select the[Code] option by pressing/ (quick touch)
and entering the access code 123 (one hundred and twenty-three) using the < > keys, and ou
confirm with /.
10.3 Date and time adjustment
When the [ClO,]menu is selected, if the access code [123,]has been entered, the controller will
enter the date and time adjustment mode. Use to change the value and press/when ready <or>
to save the configured value. If the date entered is invalid, the message [ECLO] will be shown on the
display.
Example 1 (correct access code entered):
[,00d]- day [,00M]- mouth [,00Y]- year [00:00]
time minute
flashing
IMPORTANT:
The controller has an auxiliary internal power supply to keep the clock running for at least 72 hours in
case of power failure. If the controller remains off for a long period of time, the message [ECLO], may
be displayed to indicate that the clock is not programmed. In this case, the date and time must be
adjusted and the controller must be kept on for 10 hours to fully recharge the auxiliary power supply.
NOTE: If the controller's clock is not programmed (message [ECLO]) it is possible to adjust the time
even when the functions are locked (message [LOC,] ). Under these conditions the clock adjustment
is enabled and the other functions remain locked. After the clock is adjusted the adjustment function is
locked again.
10.4 Event schedule operation mode
In the main menu (after entering the code 123) select the option [ModE] and then the desired function
using the<and>keys. The factory default for the controller is [It7,]- Daily Programming. To
leave the menu and return to the normal operating mode (temperature indication), hold down/(long
touch) until [----]appears.
[IbI,]- Weekly Programming: In this mode the instrument can configure up to 8 events for each
day of the week.
[2t6,]- Weekdays Programming: In this mode, the instrument keeps the same events from
weekdays (Monday to Friday) and allows you to program different events for Saturday and Sunday.
[It7,]- Daily Programming: In this mode, the instrument keeps the same events for all days of the
week.
10.5 Event schedule programming
This option allows entering the values of the time intervals for each event. Data input depends on the
configured operation mode. Up to eight events may be configured for each day. The start time and end
time of each event is set using options [,OnI] to [,On8] [Off8], where:
[,On1] - Start time of the 1st event.
[OFF1] - End time of the 1st event.
.
.
.
[,On8] - Start time of the 8th event.
[OFF8] - End time of the 8th event.
To configure the event schedule on menu [Prog]:
a) Press <and>(quick touch) simultaneously, the option [Code], will be displayed to request the
access code.
b) Press / and enter the access code 123 using the <or>keys, confirming with /. The option
[Code]will appear again.
c) Browse the menu using the<or>key until the option[Prog]appears, and then press /.
The following programming options may be displayed depending on the operation mode:
[IbI,]- Weekly programming
[mode]
[,,p1]- Sunday
[,,p2]- Monday
[,,p3]- Tuesday
[,,p4]- Wednesday
[,,p5]- Thursday
[,,p6]- Friday
[,,p7]- Saturday
[2t6,]- Weekdays programming
[,p26]- Monday to Friday
[,,p7]- Saturday
[,,p1]- Sunday
[It7,]- Daily programming
[,p17]- Everyday
Events programmable by day
[,0n1]- Start time of the
1st event
[0ff1]- End time of the
1st event
[,0n8]- Start time of the
1st event
[0ff8]- End time of the
1st event
.
.
.
If it is not necessary to use all the eight events then they may be configured in the disabled mode by
increasing the switch off time ([Off1] for instance) until [Off,]is displayed. It is also possible to
configure an event to cross midnight by incrementing the switch off time until the option [Cro,] is
displayed and adjusting an event for the following day starting at 12: 00 AM.
d) The time configured for the chosen event will be displayed. Use the<or>key to change the time
and press / again to return to the event programming menu.
e) To leave the event programming menu and return to the home screen, press/until the message [-
---]is displayed.
NOTE: By default the event schedule comes with all events disabled.
NOTE 2: When the event schedule operation mode is changed all events return to the default, i.e.
disabled.
