SolA i r Wor lds hot water system is commonly referred to as a Tri - system, it i s made up of six components. These six components are collector, storage tank, pump, controller, boost element and air conditioner unit.. A Tri - System is a system where the heated water in the solar collector is moved around by using a small circulation pump and pump controller. The pump draws water from the cold water connection to the tank and circulates the water through the collector, then returns the water back to the storage tank which has been heated free from the sun. When the air conditioner is fitted the refrigerant from the air conditioner passes through a coil inside the tank acting like a heater element in a kettle. When the air conditioner is operating it will heat the water for free.

ApplicationThe pump is developed to be used in a boiler. But it can be used in all appliances, where the forces having any effect to the housing are limited by special fixations and the requirements regarding temperature, pressure and media are fulfilled.

Circulation of liquids in : Central heating systemDistrict heating systemHot water service systemSmall industrial systemCooling systemAir-conditioning system

The pump can be used as well in open as in closed systems.

Application conditions: Pumped media:

Thin, clean, non-aggressive and non-explosive liquids without solid particles or fibres.Cooling liquids, not containing mineral oil.Domestic hot water (only CIL2S)Central heating water (regarding VDI 2035) e.g. with normal additives as antifreeze (glycol),corrosion inhibitor or cleaning agents

Maximum volume of added glycol: 40%

The kinematic viscosity of water is 1 mm2/s (1 cSt) at 20°C. If the circulator pump is used for a liquid with a higher viscosity, the hydraulic performance of the pump will be reduced. Maximum viscosity is 10 cSt.

The ambient temperature for standard pumps with a permissible liquid temperature from +2°C to +110°C should always be lower than the liquid temperature, as otherwise condensation may form in the stator housing.

2.6 Controller Functions and Default Controller Setting

The controller has the following default functions/settings from factory.

Circulation pump differential control – The circulation pump will only be activatedwhen there is sufficient solar energy present on the roof to contribute to the heat gain in thewater cylinder. This is achieved by sensing the temperature difference between the roofcollector and inlet water temperature. The water circulation will stop when the roofcollector temperature falls and not sufficiently higher than the water cylinder inlettemperature.

”: 8 oC“Pump Differential On Temp “Pump Differential Off Temp ”: 2 oC

Top out protection – In good solar conditions, the solar collector could harvest the solarenergy extremely sufficiently and quickly raise the storage water cylinder temperature.The storage water cylinder internal lining may be damaged by the high temperaturewater, which can exceed the designed operating temperature range by the tankmanufacturer.The top out function prevents the water cylinder reaching dangerously hightemperature by stopping the pump circulation to the collector, so that the water is notheated further. A solar rated high temperature non return valve must be used in the solarloop in conjunction for maximum protection.

“Top Out Temp”: 75 oC“Top Out Reset Temp”: 73 oC

Anti -freeze protection – In frost conditions, the risers in flat plate collector or heatexchangers in evacuated tube collector may freeze and cause damages. Anti - freezeprotection can sense the roof temperature and activate the pump circulation for shortperiod before the water may freeze inside.

“Anti-freeze on Temp ”: 3 oC“Anti-freeze on Temp”: 5 oC

2.10 Electric Element and Thermostat____________________

The electric element has a capacity of 3.6Kw, coupled with a thermostat to control the water temperatureof the tank. This Solar Thermostat has an auto-reset over-temperature cut-out for high yield sunshine days, taking the boost heater out of circuit. It’s auto reset so you don’t have to get up on the roof to turn it back on.This OTC protects the system against no-fault over temperature tripping. When the water temperature in the tank reduces to a normal operating level, the auto reset occurs and the heater can once again use the booster heater. The thermostat is adjustable with a temperature range from 50°C to 80°C, you can rotate the redgear adjusting setting. The normal setting is 60°C.

The ST13-70 has a unique internal fuse, protection that is designed especially for Solar Water Heaters.This internal fuse is extra protection against any electrical malfunction, but it is a one use fuse.If the fuse activates, the thermostat will need to be replaced.
