UNT Controller—Unitary (UNT) Controller
The installation site of the UNT must meet the following environmental
standards:
•
The atmosphere must be free of explosive vapors and escaping gases.
•
The atmosphere must be free of exposure to corrosive chemical or salt
vapors that might damage electrical equipment.
•
For UNT100/101, UNT110/111, and UNT140/141 series controllers,
the temperature must be maintained between 0 and 52°C
(32 and 125°F) with relative humidity (non-condensing) maintained
between 10 and 90 percent.
•
For UNT120/121 series controllers used with outdoor rooftop
applications, the temperature must be maintained between
-40 and 52°C (-40 and 125°F) with relative humidity maintained
between 10 and 90 percent. Some intermittent condensation is
tolerable. This operating temperature range is possible in the
UNT120/121 series controllers due to the heater, coated circuit board,
and BZ-1000-7 size enclosure.
The UNT is commonly packaged either in an enclosure provided by the
installation contractor, or in an AS-ENC100-0 or EN-EWC10-0 enclosure.
The UNT140/141-101 and UNT110/111-101 come mounted in an EWC10
enclosure with a 50 VA transformer. The controller requires a flat
mounting surface area to match its dimensions.
The UNT controller has the following dimensions:
•
165 x 163 x 56 mm (6.5 x 6.4 x 2.2 in.) H x W x D without enclosure
•
173 x 185 x 119 mm (6.8 x 7.3 x 4.7 in.) H x W x D with the
AS-ENC100-0 enclosure
•
229 x 406 x 191 mm (9.0 x 16.0 x 7.5 in.) H x W x D with the
EWC10 or UNTxxx-101 version
Allow enough room to install the enclosure and conduit for wiring
terminations to the controller.
