Zone Sensor Options for IntelliPak™ Control Units
Zone sensor options are available and be ordered with the unit or after the unit ships.
Following is a full description of zone sensors and their functions. Installation
instructions are on page 46. Programming instructions for the programmable zone
sensor are on page 49. See Table 40, p. 65 for the zone sensor temperature vs.
resistance coefficient curve.
BAYSENS077* Description
This zone sensor module ships with all units, and can be used with BAYSENS019,
BAYSENS020, or BAYSENS021 remote sensors. When this sensor is wired to one of
these remote zone sensors, wiring must be 18 AWG shielded twisted pair (Belden 8760
or equivalent). Refer to the specific zone sensor for wiring details. It provides the
following features and system control functions:
• Remote temperature sensing in the zone
• Morning warmup sensor
• Zone sensor for ICS™ systems
• Zone temperature averaging
When used as a remote sensor for standard zone sensor, the thermistor sensor must
be disabled.
(Possible Schematic Designation(s): 5U23, 5U26, 5U30, and 5RT5.)
BAYSENS108 & BAYSENS110 Description
These zone sensor modules are for use with cooling/heating constant volume units.
They have four system switch settings (heat, cool, auto, and off) and two fan settings
(on and auto).The zone sensor provides either manual or automatic changeover
control with dual setpoint capability.
BAYSENS108 and BAYSENS110 features and system control functions include:
• System control switch to select heating mode (HEAT), cooling mode (COOL),
automatic selection of heating or cooling as required (AUTO), or to turn the
system off (OFF).
• Fan control switch to select automatic fan operation while actively heating or
cooling (AUTO), or continuous fan operation (ON).
• Dual temperature setpoint levers for setting desired temperature.The blue lever
controls cooling, and the red lever controls heating.
• Thermometer to indicate temperature in the zone.This indicator is factory
calibrated.
(Possible Schematic Designation: 5U29)
BAYSENS110-Specific Feature: Function status indicator lights:
• SYSTEM ON glows continuously during normal operation, or blinks if system
is in test mode.
• COOL glows continuously during cooling cycles, or blinks to indicate a cooling
system failure.
• HEAT glows continuously during heating cycles, or blinks to indicate a heating
system failure.
• SERVICE blinks or glows to indicate a problem.These signals vary depending
on the particular equipment being used.
