All ACI/LM34 and ACI/LM334 sensors are polarity but not position sensitive. All ACI/LM334 Room units are
supplied with a two-pole terminal block while all ACI/LM34 Room units are supplied with a three-pole terminal block.
ACI recommends the use of 18 to 22 AWG twisted pair wires or shielded cable for all sensor installations.
All of the following units are available with corresponding terminal blocks for all connections: Room with Setpoint (RS),
Room with Override (RO), and Room with Setpoint and Override (RSO).
