RRS Economizer Controller
FIGURE 1 -
Field-installed economizer accessories with the RRS Econo-
mizer Controller utilize the P12/S12 connector for inter-con-
necting wiring to the 3 through 6 ton units equipped with
Simplicity Lite in the same manner as Honeywell W7212 and
Jade controllers in economizer accessories. Through the
P12/S12 connector, the unit-to-RRS Economizer wiring con-
nections are as follows:
• TB1 to RRS Economizer Controller C pin - Pro-
vides cabinet ground-referenced 24 volts AC com-
mon to power the RRS Economizer Controller,
economizer inputs and outputs
• Simplicity Lite G pin to RRS Economizer Con-
troller R pin - Provides 24 volts AC hot to power
the RRS Economizer Controller, economizer
inputs and outputs when Simplicity Lite operates
the indoor blower
• Simplicity Lite OCC pin to RRS Economizer
Controller OCC pin - 24 volts AC originating from
jumper or thermostat input to the Simplicity Lite
OCC screw terminal, through the Simplicity Lite
OCC output pin to the RRS Economizer Controller
• Simplicity Lite Y1 pin to RRS Economizer Con-
troller Y1 pin - 24 volts AC originating from ther-
mostat input to the Simplicity Lite Y1 screw
terminal, through the Simplicity Lite Y1 output pin
to the RRS Economizer Controller Y1 pin input
indicates there is a first stage cooling request

Economizer Controller Y1O pin output to the Sim-
plicity Lite ECON pin input allows initiation of com-
pressor operation when outdoor conditions are
not suitable for free cooling
