ZS Pro

Product Description

The OEMCTRL line of intelligent zone sensors provides the function and flexibility needed to manage the conditions important to the comfort and productivity of the zone occupants. ZS sensors are available in a variety of zone sensing combinations to address your application needs. Combinations include temperature, relative humidity, and indoor air quality (carbon dioxide or VOCs (Volatile Organic Compounds)). Built to be flexible allowing for easy customization of what the user/technician sees. Designed to work with all OEMCtrl controllers, the ZS sensor line includes the ZS Base, ZS Plus, ZS Pro and ZS Pro-F.


We offer several lines of intelligent sensors designed to work with all OEMCtrl controllers. Our sensors feature precise measurement, flexible capabilities and attractive, low-profile enclosures. Multiple models offer options for visibility and functionality so you can be sure to find exactly what you need for your application.

Key Features
Provide flexibility for any building sensing application with monitoring of key building conditions, including temperature, humidity, CO2, and VOC's
Attractive, low profile enclosure in neutral color cover complements any room decor
Combination sensing within one device efficiently reduces installation costs, wiring and wall clutter
Multiple ZS room sensors can be daisy-chained to one controller for temperature averaging or high/low select to achieve optimal control
A hidden communication port allows a laptop computer to be connected to the OEMCtrl Controller
Mounts on a standard 2 inch by 4 inch electrical box for easy installation
You choose the combinations for measurement of zone temperature and/or relative humidity, CO2, VOC
Multiple models offer a choice of options, including a large easy-to-read display, local setpoint adjustment, local override, and fan control
Large, easy-to-read LCD on the ZS Pro can be configured to display virtually any analog or digital value in your equipment. Here are some examples: zone temperature, outside air temperature, energy-saving mode icon, heating setpoint, cooling setpoint, relative humidity, CO2, VOCs, override time remaining, fan status, compressor status, alarms, and much more
Occupancy override is simple using the "Manual On" momentary push button on the ZS Pro. A single push switches the zone to an Occupied mode for a preset period of time. The user can increase or decrease the override time with the up or down arrows, and the LCD displays precisely how long the zone will stay occupied. The occupied time increment and maximum override time are fully adjustable
Zone setpoints can be changed on the ZS Pro by pressing the up or down arrow buttons. Setpoint adjust increment amount and the maximum total adjustment are fully adjustable
Pressing the "Fan Speed" button on the ZS Pro-F incrementally adjusts the fan speed of the unit. The "Clg/Htg Mode" button can be used to select among several zone operation modes that are fully adjustable
ZS Sensors with VOC

VOCs are Volatile Organic Compounds (VOCs). OEMCtrl ZS Sensors with the VOC feature actually reacts to all reducing gasses, which is any gas that gives off electrons when burnt, which includes all VOC's. Our sensor will be more sensitive to some of the more irritating ones but that is just a function of the sensing element and why this particular element is used in our sensor. Depending on the source of the information, 5,000 to 10,000 unique Volatile Organic Compounds (VOCs) exist. VOCs are chemicals that contain carbon and have boiling points below 100 degrees celsius. Most can be vapors at room temperature.

Families of VOCs detected are:

Ketones. Ketones are solvents. The best known are Acetone and Methyl Ethyl Ketone or MEK.
Organic Acids. Common organic acids are Lactic acid, Acetic acid, Formic acid, Citric acid and Oxalic acid
Amines. Amines are derivatives of ammonia.
Aliphatic Hydrocarbons. Aliphatic hydrocarbons are flammable hydrocarbons with little or no odor. Such as hexane, paraffin, methane and acetylene.
Aromatic Hydrocarbons. Aromatic hydrocarbons are flammable hydrocarbons with a discernible odor. Examples are benzene, furan, pyridine, toluene, asphaltene and picric acid.
