Remote Zone Sensor (BAYSENS077*)
This electronic sensor can be used with BAYSENS106*,
108*, 110*, 119*, or 021* Remote Panels. When this
sensor is wired to a BAYSENS119* Remote Panel,
wiring must be 18 AWG Shielded Twisted Pair (Belden
8760 or equivalent). Refer to the specific Remote Panel
for wiring details.
Remote Panel with NSB (BAYSENS119*)
This 7 day programmable sensor features four periods
for Occupied/Unoccupied programming per day. Either
one or all four periods can be programmed. If the
power is interrupted, the program is retained in
permanent memory. If power is off longer than 2 hours,
only the clock and day may have to be reset.
The front panel allows selection of Occupied/
Unoccupied periods with two temperature inputs
(Cooling Supply Air Temperature and Heating Warm-
up temperature) per occupied period. The occupied
supply air cooling setpoint ranges between 40º and 80º
F. The warm-up setpoint ranges between 50º and 90º F
with a 2 degrees deadband. The unoccupied cooling
setpoint ranges between 45º and 98ºF. The unoccupied
heating setpoint ranges between 43º and 96ºF.
N No otte e:: In modulating gas heat units, the supply air
heating setpoint is the active setpoint with a
BAYSENS119* and must be set for the heater to
function properly. The modulating furnace will
not react to the Discharge Heating Setpoint on
the NSB.
The liquid crystal display (LCD) displays zone
temperature, temperature setpoints, week day, time,
and operational mode symbols.
The options menu is used to enable or disable these
applicable functions: Morning warm-up, economizer
minimum position override during unoccupied status,
heat installed, remote zone temperature sensor, 12/24
hour time display, and daytime warm-up. See
, p. 39
for the Temp vs Resistance coefficient if an optional
remote sensor is used.
During an occupied period, an auxiliary relay rated for
1.25 amps @ 30 volts AC with one set of single pole
double throw contacts is activated.

High Temperature Sensor (BAYFRST003*)
Provides high limit “shutdown” of the unit.
The sensor is used to detect high temperatures due to
fire in the air conditioning or ventilation ducts. The
sensor is designed to mount directly to the sheet metal
duct. Each kit contains two sensors. The return air duct
sensor (X1310004001) is set to open at 135ºF. The
supply air duct sensor (X1310004002) is set to open at
240ºF. The control can be reset after the temperature
has been lowered approximately 25ºF below the cutout
setpoint.

Remote Minimum Position Potentiometer
(BAYSTAT023*)
This device can be used with units with an economizer.
It allows the operator to remotely set the position of the
economizer dampers from 0% to 50% of fresh air
entering the space.
