PI-PR-561051 0312 (Enhanced Mixing Station)

Viega Enhanced Mixing Station

The new Viega Enhanced Mixing Station provides uid

temperature modulation when connected to a variety

of heat sources. The new station is equipped with an

ECM motor pump that has a choice of seven settings.

Through the use of these settings, it will enable the

user to ne tune the pumps output to meet their

specic needs. The use of this technology will allow for

more efcient use of power resulting in energy savings.

Boiler connections can be made with ProPress, PEX

Press or copper (male pipe end) for soldering. Red

and blue caps on the ProPress ball valves clearly

indicate system supply and return connections. A

built in sensor well allows for easy mounting of control

sensors. Compatible with The Basic Heating Control.

Features

• Power consumption reduced by 50% with the

use of the permanently magnetized circulator motor

present in this station

• Ready to hang, factory tested

• Ideal for direct connect or remote locations

• The diverting valve can be manually or

electronically controlled

• Versatile boiler side connections

• Compatible with most heat sources

Product Instructions Purging Assuming that the heat source is already filled and purged: Stainless Balancing Manifolds Supply manifold: remove black caps to expose balancing valve. Use a 5mm allen wrench to open and close each circuit. Return manifold: use each blue return cap to open and close each circuit. Stainless Balancing and Flow Meter Manifolds Supply manifold: lift locking cap and turn flow meters to open and close each circuit.

Product Instructions Setting Safety High Limit The Mixing Station is provided with a pre-installed temperature safety high limit feature that allows a maximum fluid temperature to be set. This feature should be used when purging is complete and system is fully operational. To use this feature follow the steps below: If radiant system is being serviced, the safety high limit must be turned off for purging. Reset after purging. Viega...
