Zonex SAMOD Manual

SAMOD OVERVIEW
The system is designed for over-conditioned areas and prevents over-heating and over-cooling of individual or
stand alone zones. The SAMOD is an auto changeover thermostat that communicates to a fully modulating
round or rectangular damper or D-Fuser.
Auto changeover operation allows the SAMOD thermostat to change from a cooling to a heating thermostat
automatically. A duct sensor is included and installed upstream of the damper to determine the temperature
in the duct. If the SAMOD thermostat is calling for cooling and cool air is available in the duct the damper will
modulate open. A heating call will close the damper. If the sensor determines warm air is available in the
duct and the thermostat is calling for heat the damper will modulate open. The SAMOD system senses the
duct temperature and compares it to the set point vs. room temperature providing warm or cool air as
required. If the thermostat is not calling for heating or cooling the damper will modulate to 40% for
ventilation.
The SAMOD allows you to effectively control problem areas by controlling the existing air supply to the
problem room or zone. This versatile problem solver is also designed to control supplemental or
auxiliary heating devices.
Zonex auto changeover thermostat is designed to control and modulate a stand alone diffuser or damper.
Zonex offers 600 unique sizes of round and rectangular dampers for your commercial applications.
