Mechanical Specifications
Dual Thermistor Remote Zone
Sensor
This sensor will allow the customer
to reduce the total number of remote
sensors to obtain space temperature
averaging. This sensor should be
utilized with ReliaTel controls.
High Static Drive
The high static drive option shall
allow the standard motor on the 12½
and 20 ton units to operate with
improved external static capabilities.
Manual Outside Air Damper
The rain hood and screen shall
provide up to 25 percent outside air.
Motorized Outside Air Dampers
Manually set outdoor air dampers
shall provide up to 50 percent outside
air. Once set, outdoor air dampers
shall open to set position when
indoor fan starts. The damper shall
close to the full closed position when
indoor fan shuts down.
Powered Exhaust
The powered exhaust shall provide
exhaust of return air, when using an
economizer, to maintain better
building pressurization.
Roof Curb - Downflow
The roof curb shall be designed to
mate with the downflow unit and
provide support and a water tight
installation when installed properly.
The roof curb design shall allow
field-fabricated rectangular supply/
return ductwork to be connected
directly to the curb. Curb design shall
comply with NRCA requirements.
Curb shall be shipped knocked down
for field assembly and shall include
wood nailer strips.
Economizer - Horizontal
The horizontal economizer shall
contain the same features as the
downflow economizer with the
exception of barometric relief.
Remote Potentiometer
The minimum position setting of the
economizer shall be adjusted with
this accessory.
Ventilation Override Accessory
With the Ventilation Override
Accessory installed, the unit can be
set to transition up to 3 different pre-
programmed sequences for Smoke
Purge, Pressurization, and Exhaust.
The transition occurs when a binary
input on the RTOM is closed
(shorted). This would typically be a
hard wired relay output from a
smoke detector or fire control panel.
Zone Sensors
This option shall be provided to
interface with the Micro equipped
Voyagers and shall be available in
either manual, automatic,
programmable with night setback,
with system malfunction lights or
remote sensor options.
