From to description 0 4 0 = disabled: 1 = 0.5ºf: 2 = 1.0ºf: 3 = 1.5ºf: 4 = 2.0ºf 2 hvac settings the hvac settings parameter is a read only value that reports the current hvac configuration. the hvac settings must be fixed before the thermostat is joined to the z wave network. 0 4 0 0 0 from to description 1 2147483647 byte 1: normal (1) or heat pump (2). byte 2, bits 7 4: gas (1) or electric (2). byte 2, bits 3 0: # of auxiliary stages. byte 3: # of heat pump stages. byte 4: # of cool stages. 3 utility lock the utility lock parameter enables or disables the utility lock. if the utility lock is enabled, the setpoint cannot be modified directly via the thermostat screen. 0 1 0 0 0 from to description 0 255 0 = disabled, 1 255 = enabled 4 c wire/battery the c wire / battery status configuration parameter reports the status of the thermostat power source. the power state is fixed when the thermostat joins the network. 0 1 0 0 0 from to description 1 2 1=c wire, 2=battery 5 humidity reporting threshold the humidity threshold configuration parameter sets the reporting threshold for changes in the relative humidity as detected by the thermostat. 0 1 0 0 2 from to description 0 3 0 = disabled, 1 = 3% rh, 2 = 5% rh, 3 = 10% rh 6 auxiliary/emergency mode the auxiliary/emergency parameter enables or disables auxiliary / emergency heating in the thermostat. auxiliary / emergency heating is only available if the thermostat is configured in heat pump mode and with at least one stage of auxiliary heating. this command enables auxiliary / emergency heating when the thermostat is in auto mode. the thermostat set mode command with mode auxiliary/emergency heat (see 1.6.1) will enable emergency heating but only if the thermostat is in heat mode. this command should only be used on thermostats that support auxiliary/emergency heat thermostat mode. 0 1 0 0 0 from to description 0 1 0 = disabled, 1 = enabled 7 thermostat swing temperature the thermostat swing temperature parameter swing temperature on the thermostat. the swing temperature is applied to the setpoint to determine when the thermostat will turn on the hvac system. if the thermostat is heating, the swing temperature is subtracted from the heat setpoint. if the thermostat is cooling, the swing temperature is added to the cool setpoint. 0 1 0 0 2 from to description 1 8 1 = 0.5ºf, 2 = 1.0ºf, 3 = 1.5ºf, 4 = 2.0ºf, 5 = 2.5ºf, 6 = 3.0ºf, 7 = 3.5ºf, 8 = 4.0ºf 8 thermostat differential temperature the thermostat differential temperature configuration command sets the differential temperature for multi stage hvac systems. the differential temperature delta defines when the thermostat will turn on additional stages. there are two differential temperatures, one for multistage cool systems and one for multistage heat systems. if the thermostat is not configured for multistage hvac systems then these parameters have no effect. 0 2 0 0 4 from to description 4 3084 byte 1: 4 12 (heat diff temp), byte 2: 4 12 (cool diff temp) 9 thermostat recovery mode the thermostat recovery mode configuration command sets the hvac recovery mode type. the recovery mode determines when additional hvac stages are turned off as the ambient temperature returns to the target temperature. if the recovery mode is set to economy, the thermostat will turn off additional hvac stages when the ambient temperature reaches the target temperature plus/minus the differential temperature. if the recovery mode is set to fast, the thermostat will leave all stages on (assuming they were already on) until the ambient temperature reaches the target temperature. 0 1 0 0 2 from to description 1 2 1 = fast, 2 = economy 10 temperature reporting filter the temperature reporting filter parameter controls upper and lower bounds of the ambient temperature reporting. the thermostat will not report ambient temperature changes if the ambient temperature falls between these bounds. for example, if the upper bound is 80 f and the lower bound is 60 f, the thermostat will not send sensor multi level reports for ambient temperature values between 60 f and 80 f. the thermostat will only send ambient temperature changes if the thermostat has been added to an association group (see command class association) and the temperature reporting threshold is non zero (see temperature reporting threshold). 0 2 0 0 3200 from to description 0 31868 byte 1: 0 124ºf (lower bound), byte 2: 0 124ºf (upper bound) 11 simple ui mode the simple ui mode parameter controls whether the thermostats ui is in simple or normal mode. 0 1 0 0 1 from to description 0 1 0 = normal mode, 1 = simple mode texts
