Aqua Tempo Super II is an integrated air-to-water space heating and space cooling heat pump system. The outdoor heat
pump system extracts heat from the outdoor air and transfers this heat through refrigerant piping to the plate heat
exchanger in the hydronic system. The heated water in the hydronic system circulates to low temperature heat emitters
(floor heating loops or low temperature radiators) to provide space heating. The 4-way valve in the outdoor unit can
reverse the refrigerant cycle so that the hydronic system can provide chilled water for cooling using fan coil units.
The heating capacity of heat pumps decreases with ambient temperature. Aqua Tempo Super II is reserved an auxiliary
electric heater control port to provide additional heating capacity for use during extremely cold weather when the heat
pump capacity is insufficient. The auxiliary electric heater also serves as a backup in case of heat pump malfunction and
for anti-freeze protection of the outside water piping in winter.
