Honeywell TRADELINE R182J Manual

TRADELINE
These relays can be used for a variety of switching applications. Typically they provide control of line- or low-voltage
devices by a low voltage controller. See Table 1.
Models Application
R182J
For 24V thermostat
control of line voltage
devices.
R482J
Controlled by a line
voltage controller
R845A For hot water zone control
systems or spst control of
two separate loads.
R847A
Provides switching for
high-current loads such as
cooling compressors.
RA89A For switching one line
voltage load.
RA832A
For switching two line
voltage loads with a
common power source.
a
IMPORTANT: The transformer on the R182 can over-
heat when used with a series 20 thermostat if the
total resistance of the thermostat circuit exceeds
2.5 ohms. If the measured resistance of the thermo-
stat (including thermostat wire and thermostat con-
tact resistance) exceeds 2.5 ohms, add a 100 ohm,
10 watt resistor between the W and R terminals.
Table 2 gives maximum thermostat wire runs; if
longer runs are necessary, measure the resistance or
add a 100 ohm, 10 watt resistor across terminals W
and R.
