Unit Inspection (Perform Before
Operation)
1 . Visually inspect for damage inside and outside of the unit.
Note any damage. Claims for freight damage must be filed
by the consignee.
2 . Confirm unit location meets ventilation and service
clearance recommendations as stated in the installation
manual for your unit type under "Unit Clearances".
3. Confirm unit location condensate drain has been installed
as stated in the installation manual for your unit type under
"Unit Piping – Condensate Drain Connection".
4 . Confirm the discharge air temperature sensor is located in
the supply duct for units equipped with gas or electric heat.
5 . Confirm all field wiring is properly completed.
NOTICE
Remove power when making field connections. Damage to the MicroTech unit
controller could occur if connections are made with the power applied.
Confirm Main Power Supply Connections,
Phase Imbalance, and Clockwise Rotation
1 . Confirm that the electrical power wiring lugs are tight.
Check for proper voltage as per submittal and the wiring
diagram included with the unit.
NOTICE
Incoming power phase imbalance must not exceed 2% of voltage.
Using a phase sequencing tester confirm power source (or
sources if multiple) are all phased correctly for clockwise rotation.

Field Installed Sensors
Units equipped with refrigeration only controls ship with a limited
number of sensors to protect the compressors by operating within
their design performance envelope and to limit auxiliary heating
temperature rise. The field installer must provide, install, and
connect necessary sensors to control the airflow and conditioned
air temperature and humidity.
Sequence of Operations from Field
Controller
The field provided controller will must provide the sequence of
operation required by the building to meet heating and cooling
loads to the MicroTech unit controller via various inputs and
outputs related to the unit's operating state. OM 1373 may be
referenced to understand how the MicroTech full controls version
controls airflow, building pressure, and discharge air conditions.
Refrigeration Only Control (ROC)
Input and Output Descriptions
The following pages provide descriptions of the various input
and output contacts available on the Refrigeration Only Controls
MicroTech unit control. Some contacts listed below will not be
present on the unit as they depend on specific unit selection and
configuration.
Verify all the following input and output connections are properly
wired to the field controller based on the unit selection and field
controller provided sequences.
NOTICE
Remove power when making field connections. Damage to the MicroTech unit
controller could occur if connections are made with the power applied.
