8. INSTALLATION
8.2. IMPORTANT
According to the chapters of norm IEC 60364:
1:
Install protector against overvoltage on the power supply.
2:
Sensor cables and signal cables of the computer may be joined, but not in the same
electric conduit through which the electric input and the activation of the loads run.
3:
Install transient suppresors (RC filters) parallel to the loads as to increase the product
life of the relays.
8.1 ELECTRICAL CONNECTIONS
Note:
The length of the sensor cable can be increased by the user up to 200 meters using PP 2 x 24
AWG cable.
The sensor with metal tip must be installed in the solar collector, it supports a temperature of 200 º C.

6.4 UNIT SELECTION
To define the temperature unit with which the instrument is going to operate you should
access the
[Code]
function (see article 6.1 to find out how to access this function), insert
the
231 code
and press the
SET
key. The user may select the unit by pressing the keys
. or , where the messages
[,=C,]
or
[,=F,]
are alternated. Press the
SET
key
to confirm the desired unit. Next the message
[----]
will be displayed and the or
{
}
icons corresponding to the unit will be turned on.
Obs.:
While changing the unit, the controller carries the factory values in its parameters,
[,FAC]
, being necessary to perform their setting.

8.3 SUPERIMPOSED INSTALLATION
A qualified technician must perform
the installation of the device.
DO
DON’Ts
The controller MUST be installed:
- indoors, in a dry environment;
- away from electromagnetic fields;
- in a ventilated place, free from flammable
liquids and gases;
- protected by a circuit breaker of appropriate
specification for the installed load.
The controller MUST NOT be
installed:
- in wet places;
- exposed to sunlight or rain;
- in saunas, machine rooms or
bathrooms.
s
Failure to not comply the warnings will cause loss of warranty, equipment and / or
physical damage.
Turn off the network
before removing
the protection cover.
Suppressor

A1 and A2 are the
contactor coils.
Load
Suppressor
For direct activation the maximum
specified current should be taken
into consideration.
Suppressors on offer from Full Gauge Controls
Push the bottom openings
necessary for the passage of
cables;
Attach the controller to the wall using the
screws and plugs provided;
Make the electrical
connections of the controller;
For a better finish
install X system type
channels to run
cables;
Place the protective cover of
the electrical connections
and secure it with the screw
(included in package).
The top screw must not be screwed
completely, for engaging the
controller. After fitting the controller
on the top screw, secure it with the
lower screw;
Remove the protective
cover of the
connections at the
bottom of the controller;

[,F16]
- Hysteresis of the support temperature (T3) (parameter
[TEMP]
):
Temperature difference to turn on support. Through this function you may define a temperature interval
inside which the support outlet will remain turned off.
For example: if set
[temp]
=
[,45.0]
and
[,F10]
=
[,,1.0]
, the support outlet will be turned off
when the sensor T3 temperature reaches 45.0ºC, and will only turn back on when it falls below 44.0ºC
(45.0-1.0=44.0).
[,F17]
- Minimum value allowed for setting the support temperature:
[,F18]
- Maximum value permitted for configure the support temperature:
These parameters serve as lower and higher limits of parameter settings
[TEMP]
(Support heating
temperature). They are used to block the temperature settings, in order to restrain an inadequate
setting, for example, a high value may maintain the support outlet turned on for a long time, causing
elevated energy consumption.
NOTE:
When the T3 sensor in
[,F24]
is deactivated, the temperature of the support is now
referenced by sensor T2.
[,F19]
- Time of manual support activation:
Used when the user wishes to occasionally activate the support outlet out of the expected time in the
event schedule. From the manual activation, after the time programmed in this parameter has passed,
the support mode returns to AUT mode (automatic). To disable this function from dislocating the
settings for the minimum until it is displayed
[,,No]
.
[,F20]
- Operation mode of the support event schedule:
Defines the operation mode for the event schedule:
[,1b1]
- Weekly Programming - in this mode the instrument can set up to 4 different
events for each day of the week.
[,2t6]
- Programming for week days - in this mode the instrument maintains the same
events for week days (Monday to Friday) and allows programming different events for
Saturday and Sunday.
[,1t7]
- Daily Programming - in this mode the instrument maintains the same events for
every day of the week.
NOTE:
Upon altering the event schedule mode the controller loads the events with the factory values.
[,F21]
- Support outlet associated to the antifreeze T1:
When enabled, it has the purpose to assure minimum temperature in the thermal reservoir, for when it is
necessary to perform the antifreeze function (
[,F04]
). The support outlet is activated whenever the
(T3) support temperature is lower than the
[,F04]
setting (antifreeze temperature) + 20.0°C (fixed).
The hysteresis of this control is fixed and defined at 2.0° C.
For example, if set
[,F04]
=
[,,8.0]
, the support outlet will turn on when the temperature (T3) is
lower than 28.0°C and will turn off when higher than 30.0° C.
NOTE
:
This function turns on the independent support outlet of the support mode or the event schedule.
[,F22]
- Displacement of T1 sensor indication (Offset):
[,F23]
- Displacement of T2 sensor indication (Offset):
[,F24]
- Displacement of T3 sensor indication (Offset):
It allows compensating eventual deviations in T1 sensor reading (collector), T2 (reservoir) or T3
(support), originating from the sensor change or from cable length alteration.
NOTE:
Sensor T3 may be disabled by adjusting this function to the Minimum value
[,Off]
. After
sensor T3 is disabled, the backup system will be controlled by sensor T2 (tank/swimming pool).
[,F25]
- Time for function block:
Defines the time that the key to block/unblock the parameter alterations should be held down. For
further explanations, see article 5.8 – Function Block.
To disable this function move the setting to the minimum until it is displayed
[,,No]
.
[,F26]
- Display backlight Intensity (Backlight):
If the value adjusted in this function is the minimum
[,ECO]
, the intensity of the backlight of the display
will decrease to the minimum value (1) if no key is pressed for 5 seconds, If any key is pressed, the
intensity will increase to (8).
