Top ten reasons to put the controller in the ceiling versus on the wall. 

10. Can easily monitor CFM airflow and supply air temperature.

Supply air temperature and air flow are the two items you need to know to make conditions right. This is an important
feature in diagnosing problems with the HVAC control.  Without this feature it requires a technician to visit the area,
limb a ladder, and measure the supply air temperature. Historical data logs also provide valuable information. With the high cost of labor this feature saves thousands of dollars each year.

9. Is not vulnerable to older systems that do not have clean dry control air supplies

Older HVAC systems pneumatic control line's are usually always contaminated with some oil, moisture and dirt. The standard pneumatic thermostats are quite often replaced because of contamination. This also puts the S.P at risk of becoming contaminated leading to a costly emergency repair. ($500 plus Labor.) The PESC-F100 does not have small orifices and is not susceptible to contamination.

8. Will not become obsolete and is backwards compatible to future all electric upgrades.(With optional upgrade module.)

By adding a companion module (in development) the customer does not lose money when he decides to upgrade to all electric DDC control system. 

7. Wireless communications through open ceiling areas or below the ceiling.

Quite often it's clear sailing in the ceiling areas making the communications very simple and robust.

6. Room thermostat continues to control the temperature if it loses communications

By simply unplugging a router/repeater the temperature setting of the other products could get stuck in the unoccupied
setpoint position, causing an emergency service call and temperature problems. The ecWizard, just goes into auto mode and continues to control the temperature with the existing pneumatic thermostat. 

5. Main Controller is located in the ceiling area where it can't be tempered with by the general public.

 Since the main controller is located in the ceiling, it prevents the public from tampering with it and reduces replacement costs.

4. Complete shut off of heating and cooling in unoccupied mode

Damper spring ranges can change from the force of duct air pressure etc. Similar products rely on accurate spring ranges for
close off.  Actual conditions can vary the close off of the damper actuator, changing the actual spring range of the control
device.  Minimum airflow allows heat to continue flowing into the condition space.

3. Wireless Energy harvesting power supply

Energy harvesting technology eliminates the need for batteries, making the device totally sustainable. The energy is harvest from the air within the ductwork. 

2. Saves energy in VAV with hot-water reheat applications by shutting off the heating, cooling and air flow.

 The VAV with hot water re-heat is one the most popular zone controls throughout the United States.  Other devices that are similar to the ecWizard and are located on the wall cannot  work in this application because the air flow is only reduced to 50%.  55° supply air  temperature at 50% flow will pull the condition space down to extreme cold conditions.

1. Adjustable dead band setpoints on all applications

 This is a valuable energy saving sequence, especially in operations that are 24/7.
