Power 120 V~ 50 / 60 Hz or 24 V~ IEC PELV / NECR Class 2 Typical Power Consumption1 W (120 V~), 0.5 W (24 V~); Test conditions: all backlights on medium intensity, two LEDs on Regulatory Approvals
UL, cUL, FCC, NOM, IC, COFETEL
Environment Ambient operating temperature: 32 °F to 104 °F (0 °C to 40 °C), 0% to 90% humidity, non-condensing. Indoor use only.
Communications LutronR Comfort Controls communicate with the system through Radio
Frequency (RF) and must be located within 30 ft (9 m) of a repeater. System devices operate on frequencies between 431.0 MHz and 437.0 MHz.
ESD Protection Tested to withstand electrostatic discharge without damage or memory loss, in accordance with IEC 61000-4-2.
Surge Protection Tested to withstand surge voltages without damage or loss of operation, in accordance with IEEE C62.41-1991 Recommended Practice on Surge
Voltages in Low-Voltage AC Power Circuits.
Power Failure Power failure memory: should power be interrupted, the seeTempTM Wall Display will retain its programming when power is restored.
Mounting 120 V~ requires U.S. wallbox 3 ½ in (89 mm) deep recommended. 24 V~ can be used with Low-Voltage mounting bracket.
Wiring 120 V~ requires hot and neutral wiring; 24 V~ requires transformer common IEC PELV / NECR Class 2, 22 AWG (0.5 mm2) to 18 AWG (0.75 mm2) solid wiring.
