4.2.1.1 - Parameters description
It allows the preferential temperature indication to be configured. You may choose between:
temperature in the sensor 1
temperature in the sensor 2
temperature in the sensor 3
differential temperature (S1-S2)
It allows the adjustment of the differential temperature (S1-S2) to activate the water circulation pump. As
the solar collectors receive energy, the temperature in sensor S1 increases. When this temperature is at a
value established as being above the temperature of sensor S2, the pump is turned on and circulates
under the heated water, storing it in the reservoir, for example.
It allows the adjustment of the differential temperature (S1-S2) to turn off the water circulation pump. With
the pump on, the hot water circulates below and cools upwards. After which time, the temperature
difference between S1 and S2 tends to decrease. When this difference falls to an established level, the
pump is turned off and the water circulation stops.

Negative differential (S1-S2) to switch on the pump to dissipate heat
Minimum temperature at S2 to allow activating heat dissipation
Minimum temperature at sensor 1 to allow switching on the water circulation pump. To deactivate It, just
decrement the value until the message OFF is displayed.
It allows setting the minimum time the pump must be switched off before being switched on again. It
prevents switching the pump on and off at short intervals, thus increasing pump's service life. It also
defines the delay to switch on the pump after switching on the controller.
Negative differential (S1-S2) to switch on the water circulation pump. Its allows dissipating heat to
reduce any excess temperature in the water tank. To deactivate It, just increment the value until the
message is displayed.

1. DESCRIPTION
Differential temperature controller for automation of solar heating systems,
becomes simple the management of the temperature of the water in the thermal reservoirs and
swimming pools, use the solar energy better..
It acts in the command of the water circulation pump through the differential of temperature between the
solar collectors and the thermal reservoir or swimming pool. It is a dedicated instrument that has all its
parameters of configuration protected by access code.
It makes use of two solar backing outputs, that can be electric, gas, diesel or also to program the filtering
of the swimming pool. solar backing 1 is tied with an schedule that allows the configuration of up to four
daily events for each day of the week and solar backing 2 can optionally be configured for functioning in
set with the schedule.
It has functions that prevent the water freezing and overheating in the tubings and a clock with internal
battery to guarantee its synchronism, even in the energy lack, per many years. The instrument has serial
communication for connection with the SITRAD via Internet.
Product complies with CE (European Union) and ULInc. (United States and Canada).
The ULapproval is only valid for Microsol II plus models with 115/230Vac power supply.

2. APPLICATION
4.2.4 - Programming of the events schedule
In this option, you can enter the values for the time periods for each event. The entry of the data depends
on the operating mode configured. You can configure up to four events for each day. For each event, the
start and end time are configured through the options up to , where:
Start time for the first event
End time for the first event
Start time for the 4º event
End time for the 4º event
4.2.3 - Events schedule operating modeIn this option, you can choose how the events planner will operate.
- In this mode, the instrument can configure up to 4 events for every day of theweek.
- In this mode, the instrument keeps the events the same forbusiness days (Monday through Friday), and allows the programming of different events for Saturdayand Sunday.
- In this mode, the instrument keeps the events the same for all of the days of theweek.
Weekly programming
Programming for business days
Daily programming
If you do not need to use the four events, you can configure it to be deactivated, and all you have to do is
increase the off time ( for example) until the indication appears. It is also possible to
configure an event to overlap that it begins in one day and it finishes in the other, and for that you should
increase the off time until the option appears and adjust an event for the next day to start at 00h
and 00min. According to the operating mode configured, the following scheduling possibilities may be
presented.

SET
Antifreeze S1 to switch on the pump
It allows setting the temperature for which the collectors start to ice. When the temperature at the
collectors (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. To deactivate this function, just decrement the
value until the message is displayed.
Antifreeze hysteresis
Minimum antifreeze time
Overheating temperature S1 to switch off the pump
Hysteresis for the antifreeze function to switch off the water circulation pump.
Minimum time for which the antifreeze function stays on even if the temperature at sensor 1 returns to
the normal value.
It allows setting the overheating temperature of the collectors to switch off the water circulation pump.
When the temperature at the collectors (sensor 1) is higher than an adjustable value, the pump is
switched off to prevent the overheated water from circulating through the pipes and damaging them (if
PVC pipes are used).

Water pump start
Allows the facilitated adjust of the solar backing 1 temperature setpoint.
Allows the facilitated adjust of the solar backing 2 temperature setpoint.
It allows to set the operation mode of the water circulation pump, as follows:Water pump always OFFWater pump always ONCirculation 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).
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.
Shotcut to adjust the parameter F13This shortcut is used when the Microsol II plus is installed to control swimming polls heating systems. Inthis case the parameter F13 adjusts the maximum confort temperature of the pool water.
Manual activation of solar backing 1
With this option the output of solar backing 1 is manually activated. The output is deactivated after the time
adjusted in function expires. Upon entering this function again, the manual activation is overridden
and the solar backing 1 returns to automatic operation.
To disable the manual activation just configure the function to "000".
Manual activation of solar backing 2
With this option the output of solar backing 2 is manually activated. The output is deactivated after the time
adjusted in function expires. Upon entering this function again, the manual activation is overridden
and the solar backing 2 returns to automatic operation.
To disable the manual activation just configure the function to "000".
