Troubleshooting Guide

Solar Hot Water

Conergy Split System

It is important to know that there are no user serviceable components in the system, and as such,it is recommended that no covers be removed and no adjustments made to the system settings by anyone other than an authorised Conergy representative.

To save a service call you may like to review our troubleshooting guide.

If there is not enough hot water, it is recommended that the following points are considered before making a service call. If after checking the following points the problem has not been identified, please contact Superior Solar on 4323 9050 or your installer.

Low Solar Energy Input / Shading
If there have been prolonged periods of cloudy weather, or winter is approaching, it may be necessary to reconsider the permitted AES allowance for time-clock controlled systems, turn on the AES for systems with a booster isolation switch or turn on the gas supply to gas AES models.

Often trees or other buildings can shade the solar collectors, or there can be a dirt build up on the glass cover. Trees should be cut back if possible, or the system relocated if removal of the shading is not possible, in the present location. If the glass is dirty, this should be cleaned with any normal domestic glass cleaner.

Ancillary Energy Support (Booster System) not operating
For electric systems, the fuse, circuit breaker supplying the AES System should be checked.

If the time clock (where fitted) and the fuse or circuit breaker are operational and the water is cold, you can turn the booster isolator on and off to see if the electricity meter speed changes. If there is no change in speed, it indicates there may be a booster problem and a service call will be necessary. It is important to remember DO NOT open or adjust any electrical covers or devices yourself.

For gas systems the gas and electric supplies to the gas heater should be checked to ensure they are both on. If water temperature from the gas heater is below 60 degrees C and both supplies are on and the gas heater does not ignite there may be a problem and a service call will be necessary.

Excessive water discharge from the Valves?
If there is a discharge of more than 10 litres per day from any of the system’s valves, it indicates there is a problem that requires a service call.

Are you using more hot water than you think?
Often the hot water usage of showers, washing machines and dishwashers is under estimated.

Review these appliances to determine if your daily usage is greater than the storage volume of your water heater. Refer to the section “What system do I have?” in the manual to determine the storage volume of your water heater. It is also advisable to inspect tap washers etc. for leakage and replace if necessary.View all Solar Manuals here.

What should I do during holidays?
If you are going to be away for a week or more during the summer months, it is advisable to turn off the electricity supply to the AES System.

The power supply to the solar controller pump module must be left ON, so that the system can monitor and control the solar collector temperature while you are away. Whilst the system is safe with the power turned OFF, the collector can reach very high temperatures, causing high stress to their internal components.

For more information please review your system manual.

What should I do during holidays?

If you plan to be away for only a few nights, we suggest you leave the water heating system switched on.

If it is necessary to switch off the water heater, do so as outlined below:

Electric Boosted systems: Switch off the electric supply to the supplementary heating element. The switch is usually marked and located in the electricity meter box of the dwelling.

Gas Boosted systems: Switch off the electric supply to the gas booster.

To turn the system back on

Electric Boosted system: Switch on the electric supply to the supplementary heating element. The switch is usually marked and located in the electricity meter box of the dwelling.

Gas Boosted systems: Switch on the electric supply to the gas booster.

For more information please review your system manual and Rinnai’s troubleshooting guide.

Thermotec Roof Mounted System

If you are going to be away for a period of a week or more during the summer months it is advisable to turn off the electricity supply to the booster. It is a possibility that the high temperature valve in the storage tank may open for a short period to reduce the storage tank temperature while you are away. This is a normal function and does not harm the system.

Why a pressure temperature valve?
All Thermotec SUMMER solar water heaters have a high pressure relief safety valve in the hot water storage tank. This is required by law for all hot water storage appliances.
For solar water heaters that only have a pressure & temperature valve located on the storage tank it is normal for a small water discharge to occur during the heating cycle of the system. The water discharge is water expanding due to the heating process. Normally the discharge will be less than 9 litres per day.
For systems that have both a Pressure & Temperature valve and a Cold Water Expansion valve located in the cold water supply pipe work, the expansion discharge will occur through the Cold Water Expansion valve.

Troubleshooting

If there is not enough hot water it is recommended that the following points are considered before making a service call.

Low Solar Energy Input. If there have been prolonged periods of cloud or winter is approaching, it may be necessary to reconsider the permitted boosting time for time-clock controlled systems or to turn on the booster for systems with a booster isolation switch.

Solar collector shading. Often trees or other buildings can shade the solar collectors or there can be a dirt build-up on the glass cover. Trees should be cut back if possible or the system relocated if removal of the shading is not possible in the present location. If the glass is dirty this should be cleaned with any normal domestic glass cleaner.

Booster System not operating. For electric systems, the fuse, circuit breaker supplying the system should be checked. If the time clock (where fitted) and the fuse or circuit breaker are operational and the water is cold, you can
turn the booster isolator on and off to see if the electricity meter speed changes. If there is no change in speed, it indicates there may be a booster problem and a service call will be necessary. It is important to remember – Do not open or adjust any electrical covers or devices yourself.
For gas systems the gas and electric supplies to the gas heater should be checked to ensure they are both on. If water temperature from the gas heater is below 60°C and both supplies are on and the gas heater does not ignite there may be a problem and a service call will be necessary.
Is there excessive water discharge for the Valves?
If there is a discharge of more than 9 litres per day from any of the systems valves, it indicates there is a problem that requires a service call.

Are you using more hot water than you think?
Often the hot water usage of showers, washing machines and dishwashers is under estimated. Review these appliances to determine if your daily usage is greater than the storage volume of your water heater. If the system contains 300 litres of hot water and your usage is greater than 300 litres there may be periods where the water temperature is slightly lower than normal. It is also advisable to inspect tap washers etc. for leakage and replace if necessary.
