6.4.1 MAIN SCREEN TAB
6.4.1.1 Conditions
The Zone Temperature is the current Temperature inside the structure. This, and all the other
points being monitored on this screen are updated once a second. The Zone Humidity is the Humidity
Level inside of the structure. The Outdoor Temperature and Humidity are the current outdoor conditions
at the structure being monitored.
The Free Cooling is a Yes or No condition based on an Enthalpy calculation of the Outdoor
conditions. This is used to determine if the Economizer can be opened to take advantage of a Free
Cooling condition.
When a Technician enters the structure, he/she may decide to press the Occupancy Override
button on the front of the TCS22. This changes the active setpoint to that of an Occupied Mode that is
set to make conditions in the structure more comfortable for the Technician inside.
The Building Power condition is monitoring the power source to the Controller. This condition
will show ON, for utility power, or OFF, for battery or generator backup power if there is a utility power
failure.
Outdoor Enthalpy is a calculated point based on outdoor temperature and humidity.
