Thermostat
Thermostat controls are used to operate heating or cooling equipment based on a temperature set point
and temperature sensor reading. A setpoint determines the target temperature and a "deadband" deter-
mines the allowed drift from the target before activating the thermostat to return the reading to the target.
Example uses:
• Heating / Cooling HVAC equipment
• Exhaust fans
• Chillers
• Floor heating

NOTE
When configuring a thermostat on HVAC systems it is recommended to control the "heat" or "cool" output
from the thermostat function, then control the "fan" output with a off-delay count timer that is activated
from either the heat/cool output, or the thermostat control function. This will activate the fan with the heat
or cool signal and inlcude an off-delay retaining the fan on for a set time after the heat/cool signal.
See the "Programming" section for more details.
