4 SMAT ZONE S-T SMAT THEMOSTAT MODULATING ZONE THEMOSTAT ITH AUTO CHANGEOVE DISASSEMBLING THEMOSTAT Insert a small coin (dime) into the release slot located on the bottom of the thermostat. Gently twist the coin to release the thermostat from the subbase. Avoid twisting the case as this may stress the LCD and cause it to crack or bend the wiring terminal connection pins. SITCH FUNCTIONS There are eight dip switches located on the thermostat PC board. Only dip switches, and are active. SITCH - Switch is used to lock the thermostat after setup is completed. hen the thermostat is locked (ON position) a padlock icon will show on the LCD. hen locked, only setpoint changes and status functions can be accessed by the user. Do not set Switch in the ON position until all SETUP functions are completed. SITCH - Switch is used to display the space temperature and setpoint in Celsius (ON position) or Fahrenheit (OFF position). Select Celsius or Fahrenheit before proceeding to the thermostat SETUP menu. SITCH - Switch is used to select twoposition (ON) or fully modulating (OFF) damper control to best suit the specific application requirement. KE FUNCTIONS ON/OFF KE - hen the S-T is not locked, this key allows the thermostat to be turned ON or OFF. hen in the OFF position, the damper is also driven closed STATUS KE - Pressing the STATUS key displays the UNIT number, ZONE number, DUCT temperature and DAMPE position. UP/DON KES - These keys are used to increase or decrease the setpoint as well as change thermostat setup values. ENTE KE - This key is used to enter changes as well as exit the setup menu. (efer to Installation / Operation Manual for complete setup instructions) OPEATION The duct sensor wired to the S-T is designed to select the mode of operation of the damper. If the discharge air temperature is above 7 F, the damper will open on a call for heating. If the discharge air temperature is below 7 F, the damper will open on a call for cooling TEMINAL DESIGNATIONS C Vac (Common) Vac (Hot) PO Power Open PC Power Close () Duct Sensor Cooling elay Heating elay A / B Modbus Communications FACTO DEFAULT SETTINGS Minimum Heating Damper Position 0% Minimum Cooling Damper Position 0% Maximum Damper Position 00% Unit Number 00 Zone Number 00 Heating Limit 76 F Cooling Limit 68 F Actuator Speed 90 Modbus Address 0 Temperature Calibration Offset 0

5 APPLICATION: SMAT ZONE SE-HC/S, Type LT, Lay-in, T-Bar, VAV Fully Modulating Auxiliary Diffuser Specifications The Model SE-HC/S VAV Smart Zone Diffuser includes a diffuser and modulating actuator. The SE-HC/S can be used as an auxiliary damper when wired to a SE-HC/S diffuser actuator in applications where more than one diffuser is required in a single zone.

VA VAC POE DUCT SENSO (0 K ) IE TO OPTIONAL SLAVE DAMPE (UP TO 0 MA BE IED IN PAALLEL) SEQUENCE OF OPEATION: The automatic changeover duct sensor (located on the Smart Zone damper) senses whether there is warm air or cool air in the duct. If the S-T Smart Thermostat is calling for cooling and the duct sensor determines there is cool air in the duct, the damper will modulate open. If the S-T Smart Thermostat is calling for heating and the duct sensor determines there is warm air in the duct, the damper will modulate open. The green LED located on the actuator board indicates when the space temperature is. F above the thermostat setpoint and the thermostat is calling for cooling. The red LED located on the actuator board indicates when the space temperature is. below the thermostat setpoint and the thermostat is calling for heating. APPLICATION AND INSTALLATION NOTES: Use standard 8 gauge thermostat wire. A VAC 0 VA transformer will power a single Smart Zone system and up to 0 actuators. The actuator board is located on the side of the actuator. If the duct temperature is above 7 F, the zone damper will open on a call for heating. If the duct temperature is below 7 F, the zone damper will open on a call for cooling. If a single Smart Zone system or multiple Smart Zone systems are used to zone more than 0% of the total CFM served by the HVAC system, a bypass damper may be required to maintain constant system static pressure. The HVAC system should be controlled by its own space thermostat or discharge air controller. If a space thermostat is used to control the HVAC system, it must never be located in an area served by a Smart Zone. A suction line freeze stat (FS-8) should be installed when zoning more than 0% of the total CFM served by the HVAC system to protect the equipment in the event the suction line temperature drops too low (ire in series with the cooling control circuit).

A VAC 0 VA transformer is required to power thermostat and actuator. A K Ohm resistor must be wired to - relay contacts and paralleled with the duct sensor. The relay coil is wired to terminals and on the actuator board. hen the thermostat call for heating, the relay coil will be energized and the resistor will change the ohms value translating to a higher duct temperature which will drive the damper open. The electric duct heater relay coil can be wired to the actuator board and terminals. emove factory jumper as illustrated.
