Full Gauge Controls MICROSOL II plus Manual

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 UL Inc. (United States and Canada).
* The UL approval is only valid for Microsol II plus models with 115/230Vac power supply.

4.2.1.1 - Parameters description
Indication of the preferential temperature
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)
Differential for turning on the water circulation pump
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.
Differential for turning off the water circulation pump
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.
Minimum temperature at S1 to switch on the pump
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.
Pump switch on delay
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 pump to dissipate heat
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.
Minimum temperature at S2 to allow activating heat dissipation
Minimum temperature at sensor 2 to allow activating the heat dissipation functions.
