CONTROLS QUICK START
The following information will provide a quick guide to
setting
up
and
configuring
the
48/50PG
series
units
with
Comfort
Link
™
controls. Unit controls are pre-configured at the
factory for factory-installed options. Field-installed accessories
will require configuration at start-up. Additionally, specific job
requirements may require changes to default configuration
values. See the CCN and Display parameter tables and other
sections of these instructions for more details.
Thermostat Control
Wire accessory thermostat to the corresponding R, Y1, Y2, W1,
W2, and G terminals on the field connection terminal board
located at the unit control box.
The

U.CTL,
default value is for Thermostat (2) so there is
no need to configure this item.
Space Temperature Sensor Control -- Direct
Wired (T--55 or T--56)
Wire accessory space temperature sensor(s) to the T-55 terminals
on the field connection terminal board located at the unit control
box. Refer to Field-Installed Accessories section.
The

, must be set to Space Sensor (3). The jumper
wire in the installer’s packet must be connected between R and
W1 for heating mode to operate.
Space Temperature Sensor Control -- CCN
(T--58)
Install the T-58 communicating thermostat. Connect the CCN
communication bus from the T-58 to the CCN terminals on the
field connection terminal board located at the unit control box.
Configure the 48/50PG unit CCN communication element
number (see below). Configure the T-58 thermostat CCN
communication element number and also configure the T-58 with
the 48/50PG unit element number.

Space Temperature Control -- CCN Linkage
The CCN communication must be properly configured for the
48/50PG unit and all devices. Linkage configuration is
automatically done by the supervisory CCN Linkage device.

Installation of an accessory supply air temperature (SAT) sensor
in the supply duct is recommended for Linkage applications. A
supply duct SAT measurement is valid for heating mode display,
while the factory-standard internal SAT is not valid for heating
due to its location upstream of the heating section. When
installing the supply duct SAT, the heating mode display is
enabled by setting

BAUD
to desired code number for baud
rate (Default is 3 = 9600 baud).

See the Field-Installed Accessories section, control connection
tables, and CCN or Display parameter tables for required
connections and configurations.
