Pros & Cons

Pros

  • Four THP sizes share a 600–3450 RPM operating range.
  • The integrated interface supports seven timers and a dedicated Clean cycle.
  • The manual documents both discrete-input control and several RS-485 automation modes.

Watchouts

  • Only the 165 model supports both 115 and 230 VAC; the 225, 270, and 350 models require 230 VAC.
  • The motor and control have no user-serviceable internal parts.
  • Electrical service requires qualified personnel, full power isolation, and a four-minute capacitor-discharge wait.

Error Codes & Troubleshooting

E0
Motor Control Overcurrent (HW) — often a severe pump overload, lodged debris, or a binding pump.
E1
Motor Control Low Voltage — input voltage remained significantly below the nominal 115 or 230 VAC supply.
E2
Motor Control High Voltage — input voltage remained significantly above the nominal 115 or 230 VAC supply.
E4
Motor Control Power Module Hot — the pump stops until the power module returns to an acceptable temperature.
E5
Motor Control Open Output Phase — an open connection or motor-winding phase prevents output from reaching the motor.
E7
Motor Control Max Output Load — the motor remained torque-limited and could not reduce output enough to relieve the load.
E8
Motor Control EE Failure — the control could not read required values from memory.
E9
Motor Control Overcurrent (SW) — a software-detected overcurrent condition similar to E0.
E11
Motor Control Communication Lost — communication between the motor and DI board was lost.
E12
UI Key Stuck — the START/PAUSE button is stuck.
E16
Motor Stalled — the shaft cannot turn, possibly because dirt or debris has jammed the impeller.
E17
Control Over Temperature — a control-circuit temperature fault similar to E4.
E18
Motor Control Hardware Fault (Opens/Shorts) — an internal control failure that requires professional service.
E25
Reset to Factory Settings — corrupted pool settings were automatically reset; customized settings must be re-entered.
E26
Modbus Comm Lost — the connection to the central controller was lost in Remote Mode.
E27
MC Comm Lost — a communication error between the motor and the DI system control.
E29 / E30 / E31
Corrupt limits, options, or power-loss profile — cycle power only after the manual-required four-minute discharge wait.
E32
Template Mismatch — a memory-profile failure handled like E29.
E33
UI/DI Comm Lost — communication between the user interface and DI board was established at startup and then lost.
E34
No DI at Power Up — the DI communication error occurred during initial power-up.
