Information regarding the upper indirect coil
The upper indirect coil is intended to be connected to a heat genera-
tor.
Information regarding the lower indirect coil
The lower indirect coil is designed for connection to solar collectors.
To install the cylinder temperature sensor, use the threaded elbow with
sensor well provided in the standard delivery.
Information regarding continuous output
When engineering systems with the specified or calculated continuous
output, select a matching circulation pump. The stated continuous out-
put is only achieved when the rated boiler heating output ≥ continuous
output.
