Programmable Zone Sensors

Programmable zone sensors provide programming and zone temperature sensing for the self-contained unit. It allows the user to monitor room temperatures and program settings in the space, without having to access the unit control panel.

Reference programming instructions for these zone sensors beginning on page 44.

ConstantVolume Zone Sensor

BAYSENS019 Description

This seven day programmable sensor with night setback has four periods for occupied\unoccupied programming per day. If power is interrupted, the program retains in permanent memory. If power is off longer than two hours, only the clock and day may have to be reset.

The six programming keys on the front of the zone sensor allow selection of system modes (heat, cool, auto, and off), two fan modes (on and auto). The zone sensor has dual temperature selection with programmable start time capability.

The occupied cooling setpoint range is 40 to 80°F.The warmup setpoint range is 50 to 90°F with a 2° deadband. The unoccupied cooling setpoint range is 45 to 98°F.The heating setpoint range is 43 to 96°F.

Two liquid crystal displays (LCD) display zone temperature, setpoints, week day, time, and operational mode symbols.

The DIP switches on the subbase enable or disable applicable functions; i.e. morning warmup, economizer minimum CFM override during unoccupied status, Fahrenheit or Centigrade, supply air tempering, remote zone temperature sensor, 12/24 hour time display, smart fan, and computed recovery.

During an occupied period, an auxiliary relay rated for 1.25 amps @ 30 volts AC with one set of single pole double throw contacts activates.

Variable AirVolume Zone Sensor

BAYSENS020B Description

This seven day programmable sensor with night setback has four periods for occupied\unoccupied programming per day. Either one or all four periods can be programmed. If power is interrupted, the program retains in permanent memory. If power is off longer than twohours, only the clock and day may have to be reset.

The zone sensor keypad allows you to select occupied/unoccupied periods with two temperature inputs (cooling supply air temperature and heating warmup temperature) per occupied period. The occupied cooling setpoint ranges be- tween 40 and 80°F.The warmup setpoint ranges between 50 and 90°F with a 2° deadband. The unoccupied cooling setpoint ranges between 45 and 98°F. The heating setpoint ranges between 43 and 96°F.

The liquid crystal display (LCD) displays zone temperature, setpoints, week day, time, and operational mode symbols.

The DIP switches on the subbase enable or disable applicable functions; i.e. morning warmup, economizer minimum position override during unoccupied status, heat installed, remote zone temperature sensor, 12/24 hour time display, and daytime warmup. During an occupied period, an auxiliary relay rated for 1.25 amps @ 30 volts AC with one set of single pole double throw contacts activates.
