UCM Programming and Operation
EXAMPLE: If the auxiliary temperature sensor indicates a temperature of 74.0°F (23.3°C) and the
auxiliary temperature calibration offset is -1.5°F, the actual temperature used by Rover is 72.5°F
(22.5°C). Valid range: -10.0°F - 10.0°F (-5.5°C - 5.5°C).
Note: It may take 30 seconds (after a new offset is entered) before the calibration is
factored into the auxiliary temperature.
Outputs
1-3: The outputs can be either Normally Open or Normally Closed. Outputs 1 and 2 can be
edited only when the heat type is 3-Stage Hot Water. In all other cases they are set to Normally
Open. If there is a fan, output 3 is set to Normally Open and cannot be edited. If there is no fan,
output 3 can be edited if the heat type is either 3-Stage Hot Water or Hot Water with Auxiliary
Output.
Wired Zone Temperature
Value: This field displays the value of the wired zone temperature sensor after the UCM has
added the wired zone temperature calibration offset. If the zone sensor has failed or is not
present, dashes (---) appear.
Calibration: The zone temperature sensor calibration offset. The UCM adds the offset to the
value read by the zone sensor. After you add a new offset, Rover may take up to 30 seconds to
update the displayed temperature. Valid Range: -10°F - 10°F (-5.5°C - 5.5°C).
Wired Sensor
Use: This input determines the function of the wired zone temperature sensor. Select Averaged
to use the sensor as part of a wired system OR to use the sensor as an averaging sensor in an
older style wireless system.
Type: This line is used to edit the type of temperature sensor being used. The sensor type can
be selected as either Thermistor or RTD.
Note: Factory supplied sensors are thermistors.
Note: Set point vote determines the weighting of the set point vote. The range is 0-9. This number
represents the number of votes the sensor gets when the set points are averaged. If "0" is
selected the sensor gets no vote.
Wired Thumbwheel
Select the check box to enable the local thumbwheel setpoint input. If the Thumbwheel Setpoint
check box is not selected, the UCM does not respond to the following thumbwheel functions:
• Setpoint
• Ability to generate a "drive to max" command
• Ability to generate a "go unoccupied" command
Note: Disabling thumbwheel functions does not disable the On/Cancel push button
feature.
Setpoint: This line displays the value of the thumbwheel setpoint after the calibration offset
is applied. If the Thumbwheel is placed in the ** position and the ON button is pressed, the UCM
will request to go unoccupied. If the Thumbwheel is placed in the * position and the ON button
is pressed, the UCM will request a maximum override. Valid Range: 50°F - 85°F (10°C - 29.4°C)
Fail, Max, Unocc.)
Calibration: The value of the zone temperature sensor calibration offset. The UCM adds the
offset to the value read by the zone sensor. After you add a new offset, Rover may take up to
30 seconds to update the displayed temperature. Valid Range: -10°F - 10°F (-5.5°C - 5.5°C).
