Remote Panels and Sensors
Constant Volume and Single Zone VAV
Control Options
The RTRM must have a zone sensor or conventional
thermostat (CV only) to operate the rooftop unit. If using a
zone sensor, mode capability depends upon the type of
sensor and/or remote panel selected to interface with the
RTRM. The possibilities are: Fan selection ON or AUTO,
System selection HEAT, COOL, AUTO, and OFF. Refer to
Figure 21, p. 31
for conventional thermostat connections
on Constant Volume units.
The following controls are available from the factory for
field installation on Constant Volume or Single Zone VAV
units.
Zone Panel (BAYSENS106*)
This electronic sensor features three system switch
settings (Heat, Cool, and Off) and two fan settings (On and
Auto). It is a manual changeover control with single
setpoint capability.
Zone Panel (BAYSENS108*)
This electronic sensor features four system switch settings
(Heat, Cool, Auto, and Off) and two fan settings (On and
Auto). It is a manual or auto changeover control with dual
setpoint capability. It can be used with a remote zone
temperature sensor BAYSENS077*.
Remote Panel W/O NSB (BAYSENS110*)
This electronic sensor features four system switch settings
(Heat, Cool, Auto, and Off) and two fan settings (On and
Auto) with four system status LED's. It is a manual or auto
changeover control with dual setpoint capability. It can be
used with a remote zone temperature sensor
BAYSENS077*.
Variable Air Volume (non-SZ VAV) Control
Options
The RTRM must have a mode input in order to operate the
rooftop unit. The normal mode selection used with a
remote panel with or without night setback, or ICS is AUTO
and OFF.
Table 15, p. 33
lists the operating sequence
should a CV/SZ VAV zone sensor be applied to a traditional
VAV system having selectable modes; i.e. Fan selection
ON or AUTO. System selection HEAT, COOL, AUTO, and
OFF.
Default Mode Input for Discharge Air Control
For unit stand-alone operation without a remote panel or
an ICS connected, jumper between terminals J6-2 and J6-
4 on RTRM.
VHR Relay Output
For stand alone VAV unit operation, the VHR output should
be wired to drive VAV boxes to maximum position during
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
