Field Installed Options

CO2 Sensing

The CO2 sensor has the ability to monitor space occupancy levels within the building by measuring the parts per million of CO2 (Carbon Dioxide) in the air. As the CO2 levels increase, the outside air damper modulates to meet the CO2 space ventilation requirements.

Digital Display Zone Sensor

The Digital LCD (Liquid Crystal Display) zone sensor has the look and functionality of standard zone sensors.This sensor includes a digital display of set point adjustment and space temperature in F (Fahrenheit) or C (Celsius). Includes FAN and SYSTEM buttons (supports the service functions of the standard sensor). E-squared memory stores last programmed set points. Requires 24VAC (Volts AC).This sensor should be utilized with ReliaTel™ controls.

DualThermistor 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 theVentilation 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 equippedVoyagers and shall be available in either manual, automatic, programmable with night setback, with system malfunction lights or remote sensor options.
