Inside the Envision Series cont.
4-Way Reversing Valve
Envision units feature a reliable all-brass pilot operated
refrigerant reversing valve. The reversing valve operation
is limited to change of mode by the control to enhance
reliability.
Air Coil
Large low velocity air coils are constructed of lanced fin
and riffled tube. Each model features 3 rows for added
moisture removal (4 rows on 070-072). An optional
FormiShield™ air coil coating is available to further inhibit
formicary corrosion.
Blower Motor and Housing
High efficiency low rpm galvanized direct drive blower
featuring 3 speed permanently split capacitor (PSC) motor
and optional variable Speed ECM blower motor. The ECM
motor is controlled directly through the units microproces-
sor control. The lower rpm blower also reduces air noise.
All PSC motors have speed selection terminal strip on the
motor for easy speed change. All motors are vibration
isolated to reduce noise. High static options are available
in most models for both PSC and ECM motor versions.
Horizontal units can be field converted from end to side
discharge as well.
IntelliStart
TM
The optional IntelliStart single
phase soft starter will reduce
the normal start current (LRA)
by 60-70%. This allows the
heat pump to go off-grid.
Using IntelliStart also provides
a substantial reduction in
light flicker, reduces start-up noise, and improves the
compressor's start behavior. IntelliStart is available in
a field retrofit kit or as a factory installed option for all
Envision and Synergy3D units.
