Example with a 3-way valve on the last terminal
The sizing of the By-PASS is up to the installer; it is in any case recommended to include a calibration valve to balance the system.
Pump set up with the V3V accessory
The units in heat pumps, with Pump P1-P2-PI1-PI2 set up (single electropump), can be supplied with a factory-fitted 3-way diverter valve. This way it is
possible to manage the production of domestic hot water without the addition of external valves.
