“Combining health and building sciences for healthier buildings”

Heating, Air Conditioning, & Ventilation Control Solution

The AQ Thermostat is a climate and air quality control system for building with unitary roof top unit RTU’s or heat pumps. XCSpec Family of products provides a complete solution for climate control while improving air quality and saving on energy costs. The AQ is not just a communicating thermostat, it also enhances room ventilation through additional input air damper or exhaust control. The AQ thermostat provides a low-cost option for your customer to save money per square foot on the building total HVAC operating costs.

Features

Light Commercial Buildings

AQ Thermostat functionality is designed for the light commercial building space and includes:

• 2 Stage Heat and Cool, Fan
• Cool/Heat cross over, heat pump
• Heat, Cool or Auto Changeover
• 7 Day schedules with 2 or 4 Periods
• Partial or full keypad lock out
• CO2 based Occupancy algorithm available

Air Quality Detection

An embedded carbon dioxide sensor measures CO2 parts per million. The AQ Thermostat supports:

• CO2 ppm annunciated on panel
• Title 24 compliant accuracy of 50 ppm
• Automatic Background CO2 calibration

At-A-Glance Quality Indicators

• CO2 Range: Green/Good, Amber/Moderate, Red/ Caution based on ppm, congurable at installation
• Blue Indicator for Space Pressure Measurement – Solid On, Fast ash or Slow Flash – Pressure Range congured at installation
* Requires AQ Outside Transmitter
• Connection Status Indicator

Optional: Room Pressure Measurement

Indicator that shows the room air is owing through the ventilation and ltration system. Provides measurement of Space Pressure to assure positive pressure in the room.

Proportional Multi-Zone Temperate Control

Congure the AQ Thermostat with up to 4 XCSpec wireles temperature/humidity sensors distributed throughout zones in the space and dene the “weight” of each zone. AQ Thermostat manages the zone temperatures proportionally to the assigned weights providing easy zone temperature measurement and control for tenant comfort.

Economizer Control Ventilation Control

The AQ Thermostat supports a wired 0-10V output to control an input air actuator stand alone or with an economizer. Wired directly to the thermostat backplate. PPM range for control is configured at installation time.

Economizer Integration

The AQ Thermostat is designed to work with Economizers annunciating an economizer Alarm on the front panel to comply with Title 24 requirements.

Proportional Multi-Zone CO2 Controls

For Zone based CO2 control, configure the AQ Thermostat with up to 4 Wireless AQ Indoor CO2 displays. Based on the commissioning configuration, the DCV output is based on weighted CO2 values or the highest value.

Works With MicroMetl® Power Exhaust

When congured with XCSpec’s AQ Controls, the indoor pressure
information is used to determine if a building is positively or negatively pressurized. AQ Controls drives an exhaust or intake fan based on pressure parameters set up at installation time.

Comms to RTU Over The Thermostat Wires

When congured with an AQ Controls – no extra wires required. All XCSpec products communicate using the thermostat wires to the remote controls in the RTU.

SPECIFIC THERMOSTAT OPERATIONS

• 7 Day / 2 or 4 period programming
• Auto changeover
• 2 heat 2 cool
• Integrated room temperature and humidity sensor
• Room temperature calibration adjustment
• Separate heating and cooling swing adjustments
• CO2 Sensor – 0-5000ppm +/- 50pm accuracy
automatic background calibration
• Wireless communications
• Up to 4 wireless multi-zone temperature control
• Up to 4 wireless multi-zone CO2 control

SPECIFIC FOR AIRFLOW MEASUREMENT

• Outside transmitter must be installed. Only one
required er building
• Inside pressure at thermostat is compared to the outside
transmitter pressure
• Thermostat derives dierential pressure between the two
• Option to display on the thermostat panel
• Automatically calibrates pressure sensors during
unoccupied times

CLOUD PORTAL AVAILABLE FOR SITE SPECIFIC
THERMOSTAT MANAGEMENT

SPECIFIC FOR CO2 BASED OCCUPANCY

• Learning algorithm for unoccupied CO2 baseline
• Changes to occupied settings when measured
ppm higher than baseline
• Automatically remains occupied for 30 minutes
• After 30 minutes automatically converts to
schedule if CO2 is at baseline. If CO2 is above the
baseline it will continue occupied settings

FOR ECONOMIZER INTEGRATION

• O or B Relay can be recongured for occupancy out relay
to economizer input
• Alarm out from economizer wired to backplate to
annunciate on thermostat panel when active
• Demand control ventilation (DVC) output
• Congurable 0-10 or 2-10V control range
