Up to 3 additional Zones per thermostat – communicate directly with the thermostat or over the building Wi-Fi.

Zone Sensor Configurations Available:

• Temperature and Humidity – Refrigeration monitoring version available
• CO2 / Pressure
• VOCs
• Particulate Matter (PM2.5)

The Thermostat adds this information to its Ventilation Control output when additional ZONES are added to measure air quality - CO2, VOCs, and PM2.5.

Smart AQ Algorithm for Air Quality Determination and Action

• PM 2.5 focused on sub-micron size and density
• VOCs based on rapid Index change
• Highest PPM for CO2
• Ventilation Quality based on measuring Space Pressure at the sensor

  *** Requires outside air pressure reference

Master Thermostat

• Drives all the Rooftop Units (RTU) heating, cooling, ventilation, and humidity master on a resultant temperature/humidity
• Zone devices are added with a contributing weight.
• Master Thermostat calculates resultant temperature and humidity based on weighted contribution from each device.
• The resultant temperature value is displayed in a large area of the thermostat. This is what drives the chassis relay states.
• The Master Thermostat depicts "Local Temp XXX" in the battery area. This is the thermostat's contribution to the resultant.
• The Resultant Humidity value displayed in the upper left oscillates with the clock and is what drives the chassis humidity relay.
• The local thermostat humidity is displayed on the banner via RH=XX%.

Slave Thermostat

• Displays the local temperature and humidity
• If the user touches the up/down buttons, then:
  • The slave thermostat up/down buttons react to the user
  • The Thermostat will detect the change to the set point, and the Temporary hold
  • The slave sends the number of degree changes up/down to the master
• The Master updates the set point on the master thermostat.
• The Master asserts a temporary hold
• This results in a temporary hold situation and the change in the set point is reflected in the Master Thermostat.
