0-10V Powerhead for 1¼" Stainless Manifold
Part Number 15068
The Viega 0-10V powerhead is a thermo-electric
powerhead that mounts on the return valve of a Viega
1¼" stainless manifold. A 24-volt signal powers the unit
open while controlled by a 0-10V DC signal, usually from
either a thermostat or a central DDC building management
system. This powerhead is compatible with 1¼" stainless
manifolds of either shutoff/balancing or shutoff/balancing
ow meter types.
Extending the connecting cable
The powerhead cable may be extended, the length is
dependent on the number of powerheads and the gauge
of the wire used. The chart below lists recommendations
for extending the powerhead cable.
NOTE: If your project requires something outside of what
is suggested above please use the information below for
your calculations.
L = C x A/N
L= Maximum cable run length
C= Constant (269)
A= Conductor cross section (from chart below)
