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 microporcessor
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 cont
blower selection switches.

Versatec Control

The Versatec Control is a
microprocessor based board that adds
the features of emergency shutdown
(ES), night setback (NS), water freeze
detection (FS), Load Shed (LS) and
condensate overfl ow (CO). The
Versatec Control also features Optional
Field servicing LED's 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), night setback (NS), load shed
(LS), water freeze detection (FS),
and condensate overfl ow (CO).

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 ECM
blower motors.

Commercial applications using
single and dual capacity compres-
sors with either PSC or ECM 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.

available to BAS. Other features are
same as FX10 with addition of Johnson
Controls N2 compatibility.

the Envision 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.
