Remote Zone Sensor (BAYSENS077*)
This sensor can be used with BAYSENS106*, 108*, 110*,
800* remote panels. When this sensor is wired to a
BAYSENS800* remote panel, wiring must be 18 AWG
Shielded Twisted Pair (Belden 8760 or equivalent). Refer to
the specific remote panel for wiring details.
Thermostat
The unit must have a thermostat to operate.

thermostat.
• BAYSTAT155
Three Heat/Two Cool Auto changeover display
thermostat.
• BAYSENS150
Three Heat/Two Cool Auto changeover digital
display thermostat. Seven-day programmable
thermostat with night setback.
Digital Display Zone Sensor(BAYSENS135*)
LCD display provides heat, cool, auto, on, and off status.
Display includes two temperature setpoints and a lockable
setting with °F or °C indicators.
Thermostat (TCONT402AN32DA)
This thermostat is a multi-stage three heat/two cool, auto
changeover digital display thermostat. It is a
nonprogrammable, wall-mounted thermostat, and it can be
used for economizer operation.

Sensor — Symbio™ 700 with
Economizer Demand Control Ventilation
(DCV)
Demand Control Ventilation (DCV) eliminates over-
ventilation by closing the fresh air damper further than non-
CO
2
sensing systems and reducing power consumption.
DCV adjusts the fresh air damper between a DCV Minimum
Position and Design Minimum Position. DCV Minimum
Position equals non-CO
2
sensing systems minimum
damper position - 10%, or more, down to 0% open. When
the CO
2
level is greater than or equal to the DCV Minimum
CO
2
setpoint, supply fan energizes and fresh air damper
modulates between the DCV Minimum Position Setpoint
and the Design Minimum Setpoint, increasing the amount
of outdoor air flow and reducing the CO2 level in the space.
The damper will open up to the Design Minimum Position
Setpoint only. If the CO
2
level drops below the DCV
Minimum CO
2
Setpoint - 50ppm the fresh air damper will
drive to the DCV Minimum Position. If CO
2
level rises
above the Building CO
2
setpoint, the fresh air damper will
open to the Design Minimum Position setpoint.
