Zone Sensors
Shall be provided to interface with the Micro unit controls and shall be available in either manual, automatic programmable with night setback, with system malfunction lights or remote sensor options.
ConventionalThermostat Interface (CTI)
This field installed circuit board shall provide interface with electromechanical thermostats or automation systems. Not available with VAV system control.
Differential Pressure Switches
This field installed option allows dirty filter indication. The dirty filter switch will light the Service LED on the zone sensor and will allow continued unit operation.
Remote Potentiometer
A remote potentiometer shall be available to remotely adjust the unit economizer minimum position.
HighTemperatureThermostats
Field installed, manually resettable high temperature thermostats shall provide input to the unit controls to shut down the system if the temperature sensed at the return is 135 F or at the discharge 240 F.
Reference Enthalpy Kit
Field installed enthalpy kit shall provide inputs for economizer control based upon comparison of the outside air stream to a definable enthalpy reference point. May also be factory installed.
Comparative Enthalpy Kit
Field installed enthalpy kit shall provide inputs for economizer control based upon comparison of the enthalpies of the return and outdoor air streams. Also available factory installed.
