WARNING.
The satellite can be used in closed boiler rooms for operation
with non-aggressive fluids (water, glycol-based water in compliance with VDI
2035/ÖNORM 5195).
WARNING.
Max. working differential pressure for the primary side = 4 bar
(priority valve)
• G 3/4“F connections with adjustable tail pieces.
• Electronic thermoregulation with Set-point, to manage the DHW temperature and heating temperature.
