10.2.1. Description of parameters
F01 - Access Code:
has two different access codes:
[,123] Allows changing the advanced parameters.
[,231] Allows choosing the units of temperature: Celsius or Fahrenheit.
F02 - Preferred indication:
This function allows configuring the default temperature indication. The options are:
[T-1,]Displays the temperature of sensor 1
[T-2,]Displays the temperature of sensor 2
[T-3,]Displays the temperature of sensor 3 (if enabled)
[dif,]Displays the differential temperature (T1-T2)
[All,]Alternate display of the temperatures
When the differential temperature is being displayed (T1-T2) the two LEDs corresponding to these
sensors remain on.
F03 - Differential (T1-T2) to switch the pump on:
As the solar panels receive energy, the temperature in sensor 1 increases. When this temperature is at
an ascertainable value above the temperature of sensor 2, the pump is switched on and circulates the
heated water down, storing it in the tank for example.
F04 - Differential (T1-T2) to switch the pump off:
Allows configuring the temperature difference in degrees between sensor 1 and sensor 2 for
to switch on the water circulation pump.
Example:
[,F03]= 8.0
[,F04]= 4.0
When sensor 1 (panel) is at 35°C and sensor 2 (tank or pool) is at 23°C, the difference will be 12ºC.
Thus the circulation pump will be on (35-23 = 12 greater than 8). With the pump on, the warm water
circulates down and the cold water circulates up. Thus the temperature difference between 1 and 2
decreases. Thus, when the difference between sensor 1 and sensor 2 reaches 4º C (function F03), the
circulation pump will be switched off (35-31 = 4).
IMPORTANT: The value adjusted in function [,F03] must be higher than the value adjusted in
function[,F04]. Therefore oes not allow making invalid adjustments in order to
ensure its perfect operation.
Ex.: Current configuration:
[,F03]: 10.0°C
[,F04]: 5.0°C
You want to change it to:
[,F03]: 4.0°C
[,F04]: 2.0°C
First adjust [,F04] to 2.0°C and then adjust[,F03]to 4.0°C.
F05 - Antifreeze temperature (S1) to switch the pump on:
When the temperature at the panels (sensor 1) is too low (e.g. winter nighttime), the pump is switched
on at regular intervals to prevent the water from freezing and damaging the pipes. The hysteresis is
fixed at 2°C (4°F). The minimum time the pump is on is 3 minutes. While the pump is switched on due to
the antifreeze, message [ICE,]is alternated with the default temperature indication. This function
can be disabled by adjusting it to the minimum value [OFF,].
F06 - Superheating temperature (S1) to switch the pump off:
When the temperature at the collectors (sensor 1) is higher than an adjustable value, the pump is
switched off to prevent the superheated water from circulating through the pipes and damaging them (if
PVC pipes are used). The hysteresis is fixed at 2°C (4°F). When superheating is detected in sensor 1,
message[HT1,]is alternated with the default temperature indication.
F07 - Superheating temperature (S2) to switch the pump off:
When the temperature in sensor 2 reaches an ascertainable value the pump is switched off to avoid
thermal discomfort. This function is used in swimming pool heating systems without the third sensor.
The hysteresis may be adjusted from 0.1 to 5.0°C (see function [,F10]). When superheating is
detected in sensor 2, message [Ht2,]is alternated with the default temperature indication.
F08 - Superheating temperature (S3) to switch the pump off:
When the temperature in sensor 3 reaches a configured value the pump is switched off to avoid thermal
discomfort. This function is used in swimming pool heating systems with the third sensor to measure the
temperature on the water surface. The hysteresis may be adjusted from 0.1 to 5.0°C (see function
[,F11]). When superheating is detected in sensor 3, message[HT3,]is alternated with the default
temperature indication. This function may be disabled by adjusting it to the maximum value [Off,],
and thus sensor 3 will be disabled too.
F09 - Cooling (if sensor 3 is enabled):
Cools the pool during the night whenever the superheating temperature of this sensor is exceeded and
the temperature difference between sensor 1 and sensor 2 reaches -4°C (-7ºF), the pump is then
switched on using the panel as a radiator to cool the pool water. When the difference (T1-T2) drops to
-2°C (-4ºF) or the temperature in sensor 3 displays superheating, the pump is switched off.
NOTE: If the value of this function is [On,,], and disabled the sensor 3 the value of this function
returns to[Off,].
F10 / F11 - Superheating temperature hysteresis of sensor 2 / sensor 3:
If the pump is off due to superheating in sensor 2 or sensor 3 this function can define a temperature
range within which the pump will remain off.
F12 / F13/ F14 - Indication offset of sensor 1/ sensor 2/ sensor 3:
It allows compensating possible deviations in the temperature reading caused by the replacement of
the sensor or changes in the cable length.
F15 - Linking of sensor S3 to the automatic mode (if sensor 3 is enabled):
[no,,]Circulation pump operating in automatic mode and not linked to sensor 3. With this mode the
pump is activated only by the temperature differential (S1-S2).
[yes,]Circulation pump operating in automatic mode and linked to sensor 3. With this mode the
pump is activated by the temperature differential and when the temperature at sensor 1 is higher than
that at sensor 3.
NOTE: When the value of this function is[yes,] it will return to [no,,]when sensor 3 is disabled.
F16 - Minimum temperature in S1 to activate the pump:
Prevents the pump from being turned on when the temperature of the panel (collector) is below the
desired temperature, thus preventing warm or cold water from circulating through the system, which
would cause higher power consumption.

Example: If the panels are at 27°C and the pool is at 28°C the circulation pump does not need to be
activated. This function can be disabled by adjusting it to the minimum value[Off,].
NOTE: This function has priority over the other pump activation functions except for the manual
activation.
F17 - Instrument energization delay:
With this function enabled, when the instrument is energized, it only works as a temperature indicator
remaining with the output off during the defined time. In installations with several units of equipment,
configuring different values for the start-up delay time of each instrument, it is possible to avoid demand
peaks by activating the loads at different times. This function can be disabled by adjusting it to the
minimum value 0 [no,,].
F18 - Functions lock mode:
It allows and configures the functions lock.
[,,,0]Do not allow the functions lock.
[,,,1]It allows a partial lock where the control functions will be locked but the adjustment of the
setpoint and maximum and minimum record views are allowed.
[,,,2]It allows the full lock, enabling only view and maximum and minimum record.
F19 - Time for functions lock:
Allows lockdown of control functions (see item 9.3).
[,,15] - [,,60] - Defines the time in seconds for the controller to activate.
F20 - Control functions shutdown:
Allows the turning off of the control functions (see item 9.4).
[,,,0]Disables the control functions shutdown.
[,,,1]Enables activation/deactivation of the control functions only if the functions are unlocked.
[,,,2]Enables activation/deactivation of the control functions even if the functions are locked.
[,,,3]Enables the activation/deactivation of the control functions only if the functions are unlocked,
switching off the display.
[,,,4]Enables activation/deactivation of the control functions even if the functions are locked,
switching off the display.
NOTE: In options 3 and 4 the display is switched off if no keys are pressed and switched on when any
key is pressed, remaining on for five seconds.
