High Temp Probe 1

High Temp Probe 2

High Temp Probe 3

High Temp Probe 4
The temperature associated with a probe has gone above the high temperature alarm point and past any alarm biasing.
  1. Try lowering the temperature by turning heaters down or off, or by increasing or turning on cooling elements (such as fans or misters), or by a combination of both.
  2. Check the temperature probes.
  3. Check to see if a fan has failed.
  4. Check settings.
  5. Check if probe averaging is enabled and configured correctly.

Low Temp Probe 1

Low Temp Probe 2

Low Temp Probe 3

Low Temp Probe 4

The temperature associated with a probe has gone below the low temperature alarm point.
  1. Try to raise the temperature by turning heaters up or on, or by decreasing or turning off cooling elements (such as fans or misters), or by a combination of both.
  2. Check the temperature probes.
  3. Check to see if a heater has failed.
  4. Check settings,
  5. Check if probe averaging is enabled and configured correctly.

Probe 1 Shorted

Probe 2 Shorted

Probe 3 Shorted

Probe 4 Shorted
An active temperature probe has shorted.
  1. The next active Probe will be used. If Averaging is ON, the defective probe will be excluded from the average.
  2. Replace the temperature probe. The control should recover automatically.

Probe 1 Absent

Probe 2 Absent

Probe 3 Absent

Probe 4 Absent
An active temperature probe has disconnected.
  1. The next active Probe will be used. If Averaging is ON, the defective probe will be excluded from the average.
  2. Reconnect the temperature probe. The control should recover automatically.
Actuator 1 Jam
Actuator 2 Jam
The Supra is attempting to open or close an inlet or other element operated by an actuator, and has not received the correct response from the positioning motor.
  1. Check the element controlled by the actuator to see if it is mechanically stuck.
  2. Check the feedback wires for damage.

Error (for a relay during the status display)

You have configured an “open relay” for an actuator or curtain, but not a “close relay”.
  1. Check the relay configuration and configure the close relay.
Low AC Line Frequency
High AC Line Frequency
The AC line frequency is outside acceptable limits (±3 Hz at rated line frequency). There is a danger of damaging the control if this condition persists.
  1. Consult your local power company.
  2. If using generator power, adjust the generator frequency to 60Hz (or 50Hz).
Low Power Volt
High Power Volt
AC power supply is outside acceptable limits (+10%/-20% at rated line voltage).
  1. Consult an electrician or your local power company.
PC Comm. Alarm
The communication cable between the Supra and the computer is damaged or disconnected.
  1. Check the cable.
  2. Verify that cable leads are properly seated in terminal block.
