1 Aqua Tempo Super II System
1.1 System Schematic
Figure 1-1.1: System schematic
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.

4 System and Design Unit Selection
4.1 Selection Procedure
Step 1: Total heat load calculation
Calculate conditioned surface area
Select the heat emitters (type, quantity, water temperature and heat load)
Step 2: System configuration
Decide whether to enable or disable auxiliary electric heater
Step 3: Selection of outdoor units
Determine required total heat load on outdoor units
Set capacity safety factor
Select power supply
Provisionally select Aqua Tempo Super II unit capacity1 based on nominal
capacity
Correct capacity of the outdoor units for the following items:
Outdoor air temperature / Outdoor humidity / Water outlet temperature2 /
Altitude / Anti-freeze type
Is corrected Aqua Tempo Super II unit capacity ≥ Required total heat load
on outdoor units3
Yes No

Select a larger model or enable
auxiliary electric heater operation
Notes:
1. Up to 16 units can be connected together, giving a system cooling/heating capacity range of 30kW to 1440kW.
2. If the required water temperatures of the heat emitters are not all the same, the Aqua Tempo Super II’s outlet water temperature setting should be set at
the highest of the heat emitter required water temperatures. If the water outlet design temperature falls between two temperatures listed in the outdoor
unit's capacity table, calculate the corrected capacity by interpolation.
3. If the outdoor unit selection is to be based on total heating load and total cooling load, select Aqua Tempo Super II units which satisfy not only the total
heating load requirements but also the total cooling load requirements.

4.2 Aqua Tempo Super II Leaving Water Temperature (LWT) Selection
The recommended design LTW ranges for different types of heat emitter are:
 For floor heating: 30 to 35⁰C
 For fan coil units: 30 to 45⁰C
 For low temperature radiators: 40 to 50⁰C
4.3 Optimizing System Design
To get the most comfort with the lowest energy consumption with Aqua Tempo Super II, it is important to take account of
the following considerations:
 Choose heat emitters that allow the heat pump system to operate at as low a hot water temperature as possible
whilst still providing sufficient heating.
