Standard solar power system with heating circuit for the SH 7 Compact Top model.

- The solar system heats a hot water cylinder which serves as a buffer tank. This buffer tank is used to heat the domestic hot water and simultaneously transfer heat to the heating circuit return. The assigned relay is connected when the difference in temperature between the buffer tank and the return is greater than the connection temperature difference.

Fig.16 System 5

Standard solar power system with pool and heating circuit for SH 7 Compact Top model.

- The solar system is used to provide DHW and heating as a priority and, once this demand has been met, any surplus heat is used to heat the pool. The solar system heats a hot water cylinder which serves as a buffer tank. This buffer tank is used to heat the domestic hot water and simultaneously transfer heat to the heating circuit return. The assigned relay is connected when the difference in temperature between the buffer tank and the return is greater than the connection temperature difference. Also, when the buffer tank reaches the setpoint temperature, if the collectors sensor S1 is greater than the pool sensor S4, the second primary pump is activated, thereby using the surplus solar power to heat the pool.

6 Installation

6.1 General

The following observations must be taken into account for the hydraulic unit installation:

• Once all the hydraulic connections have been completed, check the sealing of the entire circuit.
• It is helpful to protect the collectors from the potential effects of solar radiation once the packaging has been removed, until the installation has been filled.
• If there is no demand, or it is anticipated that there will be long periods without any DHW being extracted, it is recommended to protect the system using thermal blankets.
• Once all the connections on the solar control box sensors have been completed, it is important to check that these do not run across other electrical cables as this could generate interference and alter the readout values.
• It is recommended to use a shielded cable for the sensor connections.

Before installing the solar unit, the entire installation needs to be cleaned.

The solar unit must always be installed at a lower level than the collectors so that no vapour can enter the expansion vessel in case of a blockage.

If the expansion vessel is installed at the same or a higher level than the solar unit, a heat insulation circuit is required.

The installation must be rinsed with fresh water after each draining process.

The solar unit is not suitable for direct contact with pool water or solvents.

Atención

Do not use any lubricant or grease on the installation, as this can damage the seals. Any particles of dirt, grease or lubricant residue must be rinsed out of the installation prior to installing the solar unit.

Do not use any solvents to clean the system, as this can damage plastic parts such as the pump impellers.

8.1 Operating data

Fig.25 Solar pump operation panel

BA-0000152-01

The pump UPM3 Solar is a high-efficiency pump designed to function with and without the PWM signal, therefore enabling the following curves:

• 3 Constant curves (functioning without PWM signal)
• One PWM curve with solar profile C (stopping without PWM signal)

Importante

The pump is preset to curve with profile C PWM by default.

Importante

If the controller does not have an PWM output, do not connect the signal cable and program the pump with constant curves.

The UPM3 Solar operation panel is designed with a single button, one red/green LED and four yellow LEDs.

The operation panel displays:

• Control mode
• Status of alarms.

8.2 Pump status

If a pump has detected one or more alarms, LED 1 will change from green to red and one of the other LEDs will go yellow. Refer to the faultfinding information

If multiple alarms are active at the same time, the LEDs will only display the highest priority error. The priority is defined by the sequence in the table shown in the faultfinding information.

Tab.11 Sequence of error alarms

LED 1	LED 2	LED 3	LED 4	LED 5	Indications	Pump operation	Action
x	x				Rotor blocked	Attempt restart every 1.33 seconds	Wait and unblock the shaft
x	x				Voltage supplied too low	Warning only, pumps continues to run	Check the voltage supplied
x	x				Electrical fault	The pump has stopped running because the voltage supplied is low, or there is a serious fault	Check the voltage supplied. Replace the pump

When there are no active alarms, the operation panel returns to operational mode.

It works with an external solar profile PWM C or in internal control with constant curve.

11 Troubleshooting

11.1 General malfunctions

Always disconnect the unit from the power supply before removing the cover from the solar control.

Tab.26 General malfunctions

Fault Possible cause Solution
The collector field installation does not heat the accumulator water.	The surface of the collectors is dirty.	Clean the surface of the collectors.
	The flow rate is insufficient.	Check the flow rate and, if necessary, adjust it to the correct value using the flow regulator.
	Incorrect sensor reading.	Check that the sensors are correctly positioned. If faulty, replace.
	Solar control malfunction.	Check the parameter configuration of the control. If in doubt, contact the technical department.
No fluid circulating in the installation.	The installation has not been correctly sized.	The installation's pipe network does not meet the criteria in terms of the required dimensions and arrangement, therefore the fluid cannot circulate.
	System electrical fault.	Check the electrical supply at various points in the system.
	Air found in the pump intake.	Bleed the entire system. Repeat the installation filling process if necessary.
The solar pump does not run.	The pump is blocked.	Disassemble the pump and check that there is no obstruction. If the error persists, contact the technical department.
	The solar pump is not powered.	Check the pump connections. Check the electrical supply to connection R1.
	The solar control is incorrectly configured.	Check the configuration of the solar control.
The pump starts and stops intermittently.	The temperature difference in the control is too small.	Change the ΔTon and ΔToff settings to the correct values.
	Collector sensor fitted in the wrong place.	Position the temperature sensor at the hottest output of the collector.
The pump starts running after a long delay.	ΔTon connection temperature difference too great.	Change the ΔTon and ΔToff settings to the correct values.
	Collector sensor incorrectly positioned.	When the sun is shining, briefly adjust the solar pump in manual mode, and check if the temperature of the collectors increases.
The accumulator cools down overnight.	The solar circuit pump works overnight.	Check the operating status of the pump.
		Check the configuration of the solar control.
The solar pump does not run although the temperature of the collectors is greater than the temperature of the accumulator.	The temperature difference in the control is too great.	Change the ΔTon and ΔToff settings to the correct values.
	The solar control is incorrectly configured.	Check the configuration of the solar control.
		Check the position of the sensors.
