Power Wire Sizing and Protection Devices
To correctly size electrical service wiring for a unit, find the
appropriate calculations listed below. Each type of unit has
its own set of calculations for MCA (Minimum Circuit
Ampacity), MOP (Maximum Overcurrent Protection), and RDE (Recommended Dual Element fuse size). Read the
load definitions that follow and then find the appropriate
set of calculations based on unit type.
Note: Set 1 is for cooling only and cooling with gas heat...

Field Installed Control Wiring
The Rooftop Module (RTM) must have a mode input in
order to operate the rooftop unit. The flexibility of having
several system modes depends upon the type of sensor
and/or remote panel selected to interface with the RTM. An
overall layout of the various control options available, with
the required number of conductors for each device, is
illustrated beginning with Figure 57, p. 89.
Note: All field wiring must conform to NEC guidelines as
well as...

Constant Volume System Controls
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 LEDs. It is a manual or automatic changeover control with dual setpoint
capability. It can be used with a remote zone sensor
BAYSENS077*. Refer to Table 34, p. 87for the
Temperature vs. Resistance coefficient.

Remote Minimum Position Potentiometer
(BAYSTAT023*)
The remote minimum position potentiometer is used on
units with an economizer. It allows the operator to
remotely set the economizer minimum position (which
controls the amount of outside air entering the unit). Use
the installation instructions that shipped with the
potentiometer to install it, and the appropriate illustrations
beginning with Figure 57, p. 89to connect it to the unit.
