Calculate condioned surface area
Select the heat emiers (type, quanty, water temperature and heat load)
Step 2: System conguraon
Decide whether to include AHS and set AHS’ s switching temperature
Decide whether backup electric heater is enabled or disabled
Step 3: Selecon of outdoor units
Determine required total heat load on outdoor units
Set capacity safety factor

backup electric heater operaon
Notes:
1. If the required water temperatures of the heat emiers are not all the same, the Heat Pump Split’s outlet water temperature seng should be set at the
highest of the heat emier 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 interpolaon.
2. If the outdoor unit selecon is to be based on total heang load and total cooling load, select Split units which sasfy both total heang and cooling load
requirements.
