Full Gauge Controls Microsol II power Manual

1. DESCRIPTION
Microsol II Power is a differential temperature controller for automation of solar heating systems
that becomes simple the management of the temperature of the water in the thermal reservoirs and
swimming pools, beyond the better use of solar energy .
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 makes use of two solar backing
outputs, that can be electric, gas, diesel or also to program the filtering of the swimming pool. The solar
backing 1 is tied with an schedule that allows the configuration of up to four daily events (for each day of
the week independently) 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.
Its main atractions are a versatile switched-mode power supply (90 to 264Vac) and powerful relays
(two 16-Amp and one 30-Amp) that directly commands without the need of magnetic contactors motors
up to 1HP and electrical resistances up to 7500W, saving the users investment in its appliances.
The instrument has serial communication for connection with the SITRAD , Wall-Link e Wall-Fi .

4.2.2. Parameters description
F01 - 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.
F02 - 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.
F03 - Minimum temperature at S1 to switch on the pump
Minimum temperature at sensor 1 to allow switching on the water circulation pump. To deactivate this
®
function just adjust it with the minimum value.
F04 - 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.
F05 - 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 this function just adjust it with the maximum value.
F06 - Minimum temperature at S2 to allow activating heat dissipation
Minimum temperature at sensor 2 to allow activating the heat dissipation functions.
F07 - 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 adjust it with the minimum
value.
F08 - Antifreeze hysteresis
Hysteresis for the antifreeze function to switch off the water circulation pump.
F09 - Minimum antifreeze time
Minimum time for which the antifreeze function stays on even if the temperature at sensor 1 returns to the
normal value.
F10 - Overheating temperature S1 to switch off the pump
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).
