Carrier 58HDV Installation Instructions Manual Download

Page: 38 / 52

For

two--stage

thermostat installations, the

and

wires

from the thermostat connect to the

and

connections on

the furnace control board. Set TT SW1 DIP switch #3 to ON
position. During operation, the furnace will shift from Low Heat to

High Heat as requested by the thermostat. (See Fig. 40 and wiring

diagram)
Heat anticipator setting will need to be measured if 24VAC

humidifier is installed. Measure current in series from

the thermostat. Be sure 24VAC humidifier is operating during this

check. Allow furnace to operate for 2 minutes before recording the

AC amperage reading. Set anticipator on thermostat to recorded
value.
Thermostat location has an important effect on the operation of the
furnace. Follow instructions included with thermostat for correct

mounting and wiring.
Low voltage connections to furnace must be made on terminal
board to furnace control board. (See Fig. 41)

Cooling

If single--speed cooling is used, the

Y and G

from the thermostat

must be connected to the control board

Y/Y2 and G

to energize

cooling blower speed.
If two--stage cooling is used, the

Y1, Y2, G

of the thermostat must

be connected to

of tap select interface board for low cooling,

Y/Y2

of the furnace control board for high cooling and

of the

furnace control board for continuous fan speed.

Optional Equipment

All wiring from furnace to optional equipment

MUST

conform to

local codes or, in the absence of local codes with the latest edition
of The National Electric Code, ANSI NFPA 70 and/or The

Canadian Electric Code CSA C22.1. Install wiring in accordance

with manufacturer’s instructions. The wiring

MUST

have a

minimum temperature rating of 105

Humidifier/Electronic Air Cleaner

The furnace is wired for humidifier and/or electronic air cleaner

connection.
HUMIDIFIER -- The HUM (24V) terminal is energized when the

low pressure switch closes on a call for heat. The HUM (115V) is

energized when the inducer is energized.
ELECTRONIC AIR CLEANER -- EAC terminal is energized

when there is a blower speed call, except it is NOT energized when
blower operates in the hard--wired continuous fan mode.

REDUCED FURNACE LIFE HAZARD

Failure to follow this caution may result in reduced furnace

life.
Do NOT exceed 115V/1.0 amp. maximum current load for

both the EAC terminal and the HUM terminal combined.

CAUTION

Furnace Control Board

The furnace control board has a fixed blower

delay of 30

seconds for High Heat calls and 45 seconds for Low Heat calls. The
blower

OFF

timing is factory preset at 140 seconds. If desired, the

fan

OFF

delay can be reset to obtain the longest delay times while

still maintaining comfort levels. See “Furnace Wiring Diagram”.

Dehumidification

The furnace control board has a dehumidification feature which

reduces cooling airflow by 20% when the

DEHUM

terminal (

”

male quick connect) is energized by 24VAC and there is a cooling
call.

DEHUM

may be operated by a thermostat dehumidify

(24VAC for dehumidify) command or a dehumidistat (switch closes
on call for dehumidification) with one terminal connected to (

for two--stage cooling or

Y/Y2

for single--speed cooling

applications) and the other terminal connected to

DEHUM

Furnace Control Fuse

The 24V circuit contains a 5--amp, automotive--type fuse located on

furnace control board. (See Fig. 41) Any electrical shorts of 24V

wiring during installation, service, or maintenance may cause fuse
to blow. If fuse replacement is required, use only a fuse of identical

size (5 amp.)

Tap Select Interface Board

The Tap Select Interface Board is used with the Variable Speed
motor. There are DIP switches

(SW2)

for continuous blower adjust,

heating blower adjust, cooling blower adjust and cooling on/off

delay profiles. There is a jumper

(J1)

for slight blower adjustment,

. There is a jumper

for airflow selection of Heat Pump

EFFICIENCY

COMFORT

(

EFFICIENCY

provides no airflow reduction in airflow whether

is energized or not.

COMFORT

provides a 10% reduction in

airflow when

is not energized with a cooling call).

The

terminal is available for use for Heat Pump applications, if

desired.
The

terminal (if a two--stage Air Conditioner or two--stage Heat

Pump is used) will provide low cooling blower speed when
energized. (Only

Y/Y2

on the furnace control board is used if a

single--stage Air Conditioner or Heat Pump is installed)
