Uses standard thermostat connections: (C, RC, RH, W1,W2/O, Y1, Y2, G) – 18 AWGDo NOT use for line voltage controls (120/240VAC) The thermostat can either be powered by batteries or 24VAC. Battery Powered Operation The thermostat can be powered by four AA Alkaline batteries. The thermostat will operate for approximately two years on four AA Alkaline batteries depending on the frequency of user operations and backlight operation. Always use Alkaline batteries and replace all four at the same time with NEW batteries. Z-Wave Operation when Battery Powered Important Note: If the thermostat is installed on a Z-Wave network, while it is battery powered, it does not work as a Z-Wave repeater.
24VAC Powered Operation Powering the thermostat with 24VAC power requires both the C wire (24VAC common wire - typically blue) and the R wire (24VAC hot wire - typically Red). If the C wire is not available, then batteries are required. Note! If the thermostat is powered from 24VAC, do not install batteries! Z-Wave Operation when 24VAC powered If the thermostat is installed on a Z-Wave network while it is 24VAC powered, it operates as an always-on Z-Wave repeater.
