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 backings 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).

4.2.2 - Parameters description
Indication of the preferential temperature
This function allows the preferential temperature indication to be configured. You may choose between:
Differential for turning on the water circulation pump
This function 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
This function 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 time for the pump off
This function allows the adjustment of the minimum time off that the pump should have before being turned
on again. This option avoids the pump from being turned on and off in short periods of time, which thus
increases the useful life thereof. This function also defines the delay in the pump's activation on turning on
the controller.
Temperature of the antifreeze for sensor 1 to turn the water circulation pump on
This function allows adjustment to the temperature for forming ice in the collectors. When the temperature
in the collectors (sensor 1) are very low (Ex.: winter nights), the pump is turned on from time to time, to
prevent the water from freezing in the pipes and damaging them. The hysteresis is set at 2°C/4°F. To
deactivate this function decrease the value until the message
. To confirm,
Overheat temperature for sensor 1 to turn the water circulation pump off
This function allows the adjustment of the overheating temperature of the collectors, to turn off the water
(long hit) until
circulation pump. When the temperature in the collectors (sensor 1) is above an established value, the
pump is turned off to keep the overheated water from circulating through the pipes and damaging them (if
PVC pipes are used).
Overheating hysteresis of sensor 1 to reconnect the water circulation pump
Adjustment of the hysteresis of the overheated temperature of sensor 1 to allow the water pump to be
turned on again.
Overheat temperature for sensor 2 to turn the water circulation pump off
This function allows the adjustment of the overheating temperature of the pool to turn the water
circulation pump off, avoiding thermal discomfort.
