Page 4: Solar Comfort
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. -

The operation of the controllers Relays R1 and R2 can be checked using manual switching (HND, HND1 and HND 2) see section 7. IMPORTANT No attempt should be made to repair the controller - consult Ariston. 8.4 F The following two pages have fault finding procedures. - Page 34 Is the collector sensor correctly fitted/located? Does the controller switch to ‘pump On’ (R1 On)? Set Collector Check pump wiring. Refit sensor correctly. Temperature Monitoring Suspect fault with Service / replace Function (OTC) to On controller, consult pump. Ariston.
- Page 35 Cylinders are cooled during the night. The gravitation (head) of the system may too high. Does the solar pump run during the night? Fit stronger non-return valve. Or fit electrical two way Check the controllers’ valve between the pump settings. Rever t to and the cylinder, wired default settings.
