5 Flow and pressure
5.1 Flow and pressure
Water flow in the heating system
The minimum flow rate and defrost energy must always be assured. The minimum flow rate is 1 m³/h and the recommended flow rate is
to have at least 10% margin, resulting in a recommended flow rate of 1,1 m³/h or approximately above 18 litres per minute.
The water flow can be found in SYSTEM INFORMATION - Operating data - Flow rate and it is shown in l/min. The minimum water flow
is set to 70% as default, but this needs to be adjusted that you have at least the recommended water flow as minimum water flow. In
order to adjust the minimum water flow go to SETTINGS - Circulation pumps - Condenser pump HP - Min speed. Adjust the minimum
speed of the condenser pump in order to have at least approximately 18 l/min.
Pressure loss - Athena
Recommended min. ow rate
Internal pressure loss in Athena outdoor unit.
Technical description Athena
Thermia AB AWAT01TD0102 13

Pressure loss - Heating system
Recommended min. ow rate
Total 300L Total EQ Compact
Total pressure loss in the heating system with outdoor unit and respective indoor unit.
The pressure loss in the heating system has been calculated according to an assumed standard installation consisting of Athena outdoor
units, indoor units (Total EQ/Total 300L/Compact), 10m copper pipes (Ø 28mm) and minor losses corresponding to 90° bends.

Available pressure - Rad system
Recommended min. ow rate
Total 300L Total EQ Compact
External available pressure with internal circulation pump for Athena.
When calculating the available pressure for Total EQ, the internal pressure loss was taken into account due to its two circulation pumps,
where one works towards the rad system. For Total 300L and Compact, the total pressure in the heating system was considered.
Indoor unit Unit Min Max
Total 300L l/min 18 34
Total EQ l/min 18 39
Compact l/min 18 32

6 Fan speeds
6.1 Athena H/HC
In heating mode the fan speed increases with decreasing outdoor temperature, as shown in the table above.
6.2 Recommended outdoor unit placement
Avoid placing the outdoor unit close to bedroom or living room windows. Preferable placement is instead on solid walls facing away
from any close neighbouring houses or facilities. See images below.
