THIRD PARTY CONTROL

Third party controls may interface with the unit

('Ol//Jbrtkink TM controls tba'ough the connections described

belo,a: See other sections of these instructions for more

intbnnation on the related unit control confignrations.

Thermostat -- The therlnostat inputs are provided on the

field connection terlninat board (TB2). The Therlnostat

Connol Type configuration, Configuration -+UNIT---_T.(TL,

selects the unit response to these inputs.

Y1 first stage cooling

Y2 second stage cooling

W1 first stage heating

W2 second stage heating

G indoor tan

Humidistat -- For units with the factory Humidi-MiZer TM

option, the humidistat input is provided on the field connection

terminal board (TB2). The Space Humidity Switch confignra-

tion, Configumtion---_UNIr---_RH.SW, identities the nonnalty

open or normally closed status of this input at high humidity.

Humidistat 1 24 VAC signal input

Hmnidistat 2 24 VAC source for dry contact

Humidity Sensor -- For units with the factory Humidi-

MiZer option and the economizer option with the ECB (econo-

mizer control board), the humidity sensor input is provided on

the field connection terminal board (TB2). The sensor can be

used instead of a humidistat. The RH Sensor on OAQ Input

confignration, Configumtion--_UNIT--_RH, q=YES, identi-

fies the sensor use. Default conversion to 0 to 100% relative

humidity can be changed in the confignrations.

4 4-20 mA + signal input

3 4-20 mA colrnnon

Remote Occupancy -- The remote occupancy input is

provided on the field connection terminal board (TB2). The

Remote Occupancy Switch conlignration, (bnfiguration

--->U_ClT---yRM..SVV,identifies the nonnalty open or normally

closed status of this input when unoccupied.

5 24 VAC signal input

6 24 VAC source for dry contact

Fire Shutdown -- The fire shutdo,a_ input is provided

for unit shutdown in response to a tire alarln or smoke detector.

The Fire Shutdown Switch conlignration, Configuration

-+UNIT-+FS.SW, identifies the norlnalty open or nonnatly

closed status of this input when there is no fire alarln.

For 48/50 units without Humidi-MiZer system, input at field

connection terlninal board (TB2)

Fire Shutdown 1 24 VAC source for dry contact

Fire Shutdo,am 2 24 VAC si_at input

For 50 series units with Humidi-MiZer system, input at wire

harness plug 19 (PL 19)

PL 19-3 24 VAC source for dry contact

PL 19-5 24 VAC signal input for fire shutdown

For 48 series units with Humidi-MiZer system, input at wire

harness plug 19 (PL 19)

PL 19-3 24 VAC source for dry contact

PL 19-5 24 VAC signal tbr Fire Shutdown

PL 19-4 24 VAC power for indoor fan contactor control

circuit

NOTE: For 48 series units with Humidi-MiZer system, if the

indoor fan must be shut down without any delay upon Fire

Shutdown input, then the factory julnper between PL 19-3 and

PL19-4 must be replaced with a norlnally closed contact when

there is no atann (open with atann).

Alarm Output- The alarln output is provided on the

field connection terminal board (TB2) to indicate a current

atann status. The output will be 24VAC if a current atann

exists.

C 24 VAC comlnon

X 24 VAC signal output

Outdoor Enthalpy- For units with the economizer

option or accessory and the ECB control board, the outdoor

enthalpy input is provided on the field connection terminal

board (TB2). The Enthalpy Switch confignration, (bnfigura-

tion---_E{DN--+EN..SW, identifies the nonnalty open or

normally closed status of this input when the outdoor enthalpy

is low.

6 24 VAC source for dry contact

7 24 VAC signal input
