ENVISION LOW SILL CONSOLE INSTALLATION MANUAL
Standard CCM Control Features
Compressor control module (CCM) controls are standard on
the Envision Series Low Sill Console heat pump. This control
features unit mounted thermostat and switches,
Features of the standard control are:
• Easy to understand color coded thermostat
adjustment markings.
• Large, rocker type mode and blower switches.
• Internally mounted blower switch to choose cycled or
constant blower operation.
• High pressure and low pressure safety controls to
protect the unit components.
• Lockout circuit to shut down unit operation upon receipt
of a fault indicator from the safety controls.
• A 24 volt control circuit allows for safe and
easy diagnosis.
Control General Description Application Display/Interface Protocol Thermostat Options
CCM Control The CCM (Compressor control
module) is a more reliable
replacement for electro-mechanical
control applications. It features a
small microprocessor board that
handles the lockout function of
the unit. A second microprocessor
handles the unit mounted
thermostat for maintaining accurate
room temperature. Residential and commercial
applications requiring minimal
but reliable controls. Includes
Random Start, High and low
pressure switches and auto
changeover capability. Dial thermostat with Hi
and Low blower speeds,
and auto changeover
or continuous blower
selection switches. None Unit Mounted Digital

Versatec Control The Versatec Control is a
microprocessor based board that
adds the features of emergency
shutdown (ES), water freeze
detection (FD) and condensate
overfl ow (CO). The Versatec
Control also features Optional Field
servicing LEDs for mode, Fault and
diagnostic indication. Residential and commercial
applications requiring more
controls features than CCM and
Includes Random Start, High
and low pressure switches,
auto changeover capability,
emergency shutdown (ES),
water freeze detection (FD),
and condensate overfl ow (CO). Optional fi eld

FX10 The FX10 microprocessor control
is self contained control featuring
LP, LOC, HP, LWT, and condensate
overfl ow fault modes can be
displayed on BAS system. Optional
handheld Medium User Interface
(MUI) Control can be used for
additional setup or servicing.
Program customization is possible.
This control is suited for both
single and dual capacity
compressors as well as PSC and
ECM2.3 blower motors. Commercial applications
using single and dual capacity
compressors with either PSC or
ECM2.3 blower motors. Also
suitable for multi-compressor
products. Cannot be integrated
with centralized building
automation systems.
Software can be customized for
specifi c projects. Optional Medium User
Interface (MUI) can be
used as a fi eld
service tool. Standalone Remote Mounted
