24-V WIRING
Make field 24-v thermostat connections at 24-v terminal block on
fm'nace control
For proper
cooling operation,
Y wire from
thermostat MUST be connected to ¥ terminal on filrnace connol,
as shown in Fig. 30. The 24=v terminal block is marked fbr easy
connection of field wiring. (See Fig. 320 The 24=v circuit contains
a 3=amp, automotive4ype
fuse located on fi/mace control. (See
Fig. 33.) Any electrical shorts of 24-v wiring during installation,
service, or maintenance may cause lime to blow. If filse replace-
merit is required, use only a time of identical size (3 amp) and type.
The control will flash code 24 when fuse needs replacement.
NOTE:
Use AWG No. 18 color-coded copper thermostat wire fbr
lengths up to 100 it. For wire lengths over 100 ft, use AWG No.
16 wire.
A( CESSORIES
l. Electronic Air Cleaner (EAC)
Two quick-connect
terminals marked EAC-I and EAC°2 are
provided for EAC connection. (See Fig 33) These terminals
are energized with 115v (1 0-amp maximum) during blower
motor operation.
NOTE:
DO NOT connect f:urnace control HI_M tem_inal to HUM
(humidifier) terminal on Thermidistat-f_L Zone Controller or simi-
tar device
See Thermidistat
TM,
Zone Controller, thermostat, or
controller manufi_cturer's instructions fbr proper connection.
