6b. Safety Switch
The safety switch should be connected to a Class II Low Voltage circuit. The
safety switch wires are yellow and yellow with black stripe. Do not confuse
these wires with the power conductors.
The safety switch connection is normally closed (NC). Refer to thermostat
and air conditioning or refrigeration unit’s operating instructions when
using the safety switch. Be sure to disconnect power to the air conditioning
or refrigeration unit when installing or modifying the safety switch circuit.
Connect the safety switch in series with the low voltage thermostat circuit as
specified in the thermostat’s operating manual.
