Issue
The SP90 Actuator alarm "BV:22 Temperature Sensors Missing or Interchanged" is triggered. Can we simply swap T1 and T2 in the configuration to fix this, instead of physically swapping the sensors?
Product Line
Field Devices
Environment
SpaceLogic SP90 Series Smart Actuator
Cause
The installer has installed the temperature sensors in the incorrect pipes.
Resolution
Firmware versions V439 (for actuators products marked V1xxx on the product label) and V539 (for actuators marked V2xx on the product label) introduced MSV:42 (T1 input) and MSV:43 (T2 input) which enable the temperature sensors to be swapped.
You are able to select each as:
1: Disabled
2: Supply temperature
3: Return temperature
If the SP90 actuator is at a lower firmware revision, it can be upgraded. Contact Product Support for the firmware files and upgrade instructions.
