Full Gauge 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 has functions that prevent the water freezing and overheating in the tubings.
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.In addition, it
features a real time scheduler that allows programming a weekly schedule with up to four daily events
and a clock with internal battery to guarantee its synchronism, even in the energy lack, per many years.
It is a dedicated instrument that has all its parameters of configuration protected by access code.
Product complies with CE (European Union) and UL Inc. (United States and Canada).

4.2.1.1 - Parameters description
Indication of the preferential temperature
It allows the preferential temperature indication to be configured. You may choose between:
Shows the panel temperature (solar collector);
Shows the swimming pool or thermal tank (bath) temperature;
Shows the solar backings temperature (support systems);
Shows the difference (°C) between the solar panel (sensor 1) and the swimming pool or
thermal tank (sensor 2).
Differential for turning on the water circulation pump
Allows configuring the temperature difference in degrees between sensor 1 and sensor 2 for
MICROSOL II plus
to turn on the water circulation pump.
Differential for turning off the water circulation pump
Allows configuring the temperature difference in degrees between sensor 1 and sensor 2 for
MICROSOL II plus
to turn off the water circulation pump.
Exemple:
F02= 8.0
F03= 4.0
When sensor 1 (panel) is at 35°C and sensor 2 (swimming pool or tank) is at 23°C, the difference is 12ºC,
thus the circulation pump must be on (35-23 = 12, more than 8). With time the difference between sensor 1
and sensor 2 tends to decrease. Thus when the difference between sensor 1 and sensor 2 reaches 4ºC
(function F03), the circulation pump will be turned off (35-31 = 4).
The thermostat panel has an indicator LED "PUMP" (upper left). When the LED is on, the pump is on.
When the LED "PUMP" is off, the pump is off.
Minimum temperature at S1 to switch on the pump
Prevents the pump from being turned on when the temperature of the panel (collector) is below the
required temperature, thus preventing warm or cold water from circulating through the system, which
would cause higher power consumption. To deactivate this function, just decrement the value until the
message is displayed.
Pump switch on delay
This function protects the pump from burning out in case of power fault (counts the time in seconds).
Example: When there is a power fault and the power is restored immediately after,
will first count the time programmed in function F05 before activating the circulation pump. This function
also helps to reduce the voltage surge that can happen in the protection devices (circuit breakers) when
activating many loads at the same time.
