DAMPER ADJUSTMENT

positions if desired.
The SAMOD is an Auto Changeover thermostat that modulates a zone damper based on supply air and room temperature.
System logic dictates system mode of operation. When duct temperature is 3 degrees or more below room displayed
temperature on the SAMOD thermostat, the mode is set as Cool. When duct temperature is 7 degrees or greater than room
temperature as displayed on SAMOD thermostat, then mode is set for Heat. If duct temperature is neither 3 degrees below
nor 7 degrees above room temperature displayed on SAMOD thermostat, then mode is set for Vent for continuous air
circulation.
