Electrical data (options 116B, C, F, G)
The pumps that are factory-installed in these units have
motors with efficiency class IE2. The additional electrical data
required by regulation 640/2009 is given in the installation,
operation and maintenance manual.
This regulation concerns the application of directive 2005/32/
EC on the eco-design requirements for electric motors.
Pump curve (options 116B, C, F, G)
Conditions and limits of use:
-- Fresh water 20 °C
-- In case of use of the glycol, the maximum water flow is reduced.
When the glycol is used, it’s limited to 40%.
Low-pressure pump (hydronic module option)
High-pressure pump (hydronic module option)
