atiMgmtSysTempTemperature (1.3.6.1.4.1.926.1.3.2.4.5)
Size list Description
1...70 Thermostatic temperature setpoint in degrees centigrade. When this device is set to control the temperature
device based on temperature, this variable (along with the hysteresis variable) will be used to determine when the
temperature device is to be turned on and off. This value is compared to the value from the battery temperature
sensor. The DEFAULT factory state for this variable will be 0 (once changed, it may not be put back to zero, pro-
viding an indication that the value has been adjusted). This variable is non-volatile and the value will be retained
when the device is reset.
atiMgmtSysTempHysteresis (1.3.6.1.4.1.926.1.3.2.4.6)
Size list Description
1...10 When the device is controlling the temperature device thermostatically, this value is used to keep the temperature
device from going on and off too often. If the temperature device is a heater, the device will be turned on when
the temperature reaches the setpoint but will not be turned off until the detected temperature overshoots the set
point by this amount. When the temperature device is a cooler, the device will be turned on when the temperature
reaches the set point, but will not turn off until the detected temperature undershoots the set point by this amount.
The DEFAULT factory state for this variable is 1. This variable is non-volatile and the value will be retained when
the device is reset.
atiMgmtSysTempTimer (1.3.6.1.4.1.926.1.3.2.4.7)
Size list Description
0...1440 When the temperature device is controlled using the timer, this is the number of minutes the temperature device
will be active. The DEFAULT factory state for this variable is 30. This variable is non-volatile and the value will be
retained when the device is reset.
atiMgmtSysTempCountdown (1.3.6.1.4.1.926.1.3.2.4.8)
Size list Description
0...1440 When the temperature device is controlled using the timer, this is a countdown that will indicate how many min-
utes before the device will become inactive. The value of this counter is undefined when the device is not active in
a timer mode. Anytime atiMgmtSysTempCtrl is SET to a value that indicates timer mode, the value of atiMgmtSys-
TempTimer will be copied into this variable. If, while this variable is counting down, atiMgmtSysTempCtrl is again
SET to a value that represents a timer mode, the value of atiMgmtSysTempTimer will again be copied into this
variable and the count will start over again. The temperature device will change to inactive when this count drops
to zero. At zero the counter will stop.
atiMgmtSysTempStatusInvert (1.3.6.1.4.1.926.1.3.2.4.9)
Value list Description
noInvert(1) The default value of this variable is noInvert(1), which provides a contact closure when the temperature device
is on. When this parameter is set to invert(2), the returned value for the contact status (atiMgmtSysTempStatus)
will be inverted (contact closed will be reported as open, contact open will be reported as closed). This
accommodates the differences in which the manufacturers of the relay block have implemented the open versus
closed status contacts. This variable is non-volatile and the value will be retained when the device is reset.
