You may need to recalibrate the pump to be matched with the IceCap module. When it comes to the Gyres, the module is set to query the pump when connected for the very first time, The module will then run the pump at 100% for 10 seconds while it calibrates itself. You only do this once but if you connect a different pump to the module, you should have the module recalibrate itself to match the individual pump you just connected to it.
Here is how you force the module to recalibrate itself with that specific pump:
1. Disconnect old pump
2. Plug module into power (with no pump connected)
3. Run it until the light goes Red (around 30 seconds)
4. Unplug module from power
5. Plug in new pump
6. Power up module
