The RLV4300 thermostat can be used to control an electric heating
system such as a baseboard heater, a radiant floor, a radiant ceiling,
a convector, a fan-forced heater, etc. The thermostat cannot be used
with the following:
a resistive load under 2 A
a resistive load over 12.5 A
systems driven by a contactor or a relay (inductive load)
central heating systems
One (1) thermostat
Two (2) 6-32 mounting screws
Two (2) solderless connectors
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN
POWER PANEL TO AVOID ELECTRICAL SHOCK.
Loosen the screw under-
neath the thermostat and
separate the front plate
from the back plate.
NOTE: The screw cannot
be completely removed.
Connect the thermostat wires to the power and to the load using
solderless connectors for copper wires. The thermostat wires are not
polarized; meaning either wire can be connected to the load or to the
