Field Installed Options<br />
CO Sensing<br />
2<br />
The CO sensor shall have the ability to<br />
2<br />
monitor space occupancy levels within<br />
the building by measuring the parts per<br />
million of CO (Carbon Dioxide) in the air.<br />
2<br />
As the CO levels increase, the outside air<br />
2<br />
damper modulates to meet the CO2 space ventilation requirements.<br />
Digital Display Zone Sensor<br />
The Digital LCD (Liquid Crystal Display)<br />
zone sensor has the look and functionality<br />
of standard zone sensors. This sensor<br />
includes a digital display of set point<br />
adjustment and space temperature in F<br />
(Fahrenheit) or C (Celsius). Includes FAN<br />
and SYSTEM buttons (supports the<br />
service functions of the standard sensor).<br />
E-squared memory stores last<br />
programmed set points. Requires 24 VAC<br />
(Volts AC). This sensor should be utilized<br />
with ReliaTel controls.<br />
Dual Thermistor Remote Zone Sensor<br />
This sensor will allow the customer to<br />
reduce the total number of remote<br />
sensors to obtain space temperature<br />
averaging. This sensor should be utilized<br />
with ReliaTel controls.<br />
High Static Drive<br />
The high static drive option shall allow the<br />
standard motor on the 6 and 7½ ton units<br />
to operate with improved external static<br />
capabilities.<br />
Humidity Sensor<br />
This wall-mounted humidity sensor is<br />
used to control activation of the hot gas<br />
reheat dehumidification option. The<br />
humidity sensor can be set for humidity<br />
levels between 40% and 60% relative<br />
humidity by adjusting the ReliaTel Options<br />
Module.<br />

Specifications<br />
Humidity Sensor<br />
This duct-mounted humidity sensor is<br />
used to control activation of the hot gas<br />
reheat dehumidification option. The<br />
humidity sensor can be set for humidity<br />
levels between 40% and 60% relative<br />
humidity by adjusting the ReliaTel Options<br />
Module.<br />
Manual Outside Air Damper<br />
This rain hood and screen shall provide<br />
up to 50 percent outside air.<br />
Motorized Outside Air Dampers<br />
Manually set outdoor air dampers shall<br />
provide up to 50 percent outside air. Once<br />
set, outdoor air dampers shall open to set<br />
position when indoor fan starts. The<br />
damper shall close to the full closed<br />
position when indoor fan shuts down.<br />
Powered Exhaust<br />
The powered exhaust, available for 6-10<br />
ton units, shall provide exhaust of return<br />
air, when using an economizer, to<br />
maintain better bulding pressurization.<br />
Remote Potentiometer<br />
The minimum position setting of the<br />
economizer shall be adjusted with this<br />
accessory.<br />
Roof Curb<br />
The roof curb shall be designed to mate<br />
with the unit’s downflow supply and<br />
return and provide support and a water<br />
tight installation when installed properly.<br />
The roof curb design shall allow fieldfabricated<br />
rectangular supply/return<br />
ductwork to be connected directly to the<br />
curb. Curb design shall comply with<br />
NRCA requirements. Curb shall be<br />
shipped knocked down for field assembly<br />
and shall include wood nailer strips.<br />
Thermostat<br />
Two stage heating and cooling operation<br />
or one stage heating and cooling shall be<br />
available in either manual or automatic<br />
changeover. Automatic programmable<br />
electronic with night set back shall also be<br />
available.<br />
Ventilation Override Accessory<br />
With the Ventilation Override Accessory<br />
installed, the unit can be set to transition<br />
up to 3 different pre-programmed<br />
sequences for Smoke Purge,<br />
Pressurization, and Exhaust. The<br />
transition occurs when a binary input on<br />
the RTOM is closed (shorted). This would<br />
typically be a hard wired relay output<br />
from a smoke detector or fire control<br />
panel. The ventilation override accessory<br />
shall be available as field installed.<br />
Zone Sensor<br />
This control shall be provided to interface<br />
with the Micro equipped units and shall<br />
be available in either manual, automatic<br />
programmable with night setback, with<br />
system malfunction lights, or remote<br />
sensor options.<br />
