Pi2R iX Solar Geyser Controller (100-300Vdc)

ex VAT

Description:The Pi2R iX Solar Geyser Controller (100-300Vdc) has two different operating modes, one with a display and one without.Connection without a DisplayIn this mode temperature can only be set with the existing AC thermostat. No extra settingspossible.In this mode priority is always given to grid power (AC). This enables the unit to be manuallyforced to use grid when DC power is available but not sufficient. Otherwise when DC is only at10% (for example) then the water cannot be heated up quickly if the user so required.Thus to automate functionality, AC needs to be switched through a standard geyser timer. Thistimer will enable AC at set times to ensure acceptable water. The timer also ensures that DC is usedduring sunlight hours as it removes AC during daytime.Contrary to expectation AC is not always used during these times. AC will be available but notused when the geyser is warm enoughThe Pi2R iX Solar Geyser Controller (100-300Vdc) Connection with a DisplayIn this mode all programming is done via the Display and the existing thermostat is turned up tomaximum temperature to avoid intervening with user settings while still providing a safety backup.OverrideThe geyser can be manually overridden in order to heat up once-off. Overrides will not repeatautomatically.TimersTwo independent timers can be set when AC may be used.Contrary to expectation AC is not always used during these times.AC will not be used when:Water is warm enough LoadsheddingTemperaturesTwo independent temperatures can be set. One for AC and one for DC/PV.When the Temperature reaches the AC set-point then the unit will switch to PV power if available(even during Timer operation).It is therefore important to set the AC temperature lower than the DC temperature, otherwise powersaving will be hindered.City of CapetownBoth Pi2R Micro Solar Geyser Controller and iX can be used under Capetown regulations, both are NRCS approved asrequired.
