The solar collectors are heated by the sun’s rays. The heat generated is YSTEM ORKS stored in a hot water storage cylinder e.g. an Ariston Primo twin coil stainless steel cylinder. The AST 100 Solar Controller continually compares the temperature of the water within the cylinder with the temperature of the solar collectors. - Page 5 Roof mounted collectors (two collector system shown) Air vent Energy Monitoring Sensor S4 (option) Temperature Sensor S1 Ariston ITSI 210/300 twin coil cylinder AST 100 Controller PR Valve Pump group Temperature Expansion Sensor S3 vessel Upper coil heated by boiler...

5.6 S The flow rate in the circuit is between 0.5 and 1.5 litres/min for each collector. IZING OF IPES The flow velocity in the circuit should not exceed 1.5m/sec otherwise the the system may be noisy during operation. As a guide only: systems with total pipework of less than 50 metres, 15mm diameter pipe should allow flow conditions to be met for systems with up to four collectors. -
