Switching Relays
Application
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.

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.
