- E
  Eric HernandezAug 16, 2025
  To resolve a 'No display or distorted display' issue on your Heat-Timer ETV Platinum Plus Control Module: * First, verify that the ETV Platinum Plus Control Module is receiving power and that all power wiring is in good condition and properly connected. The module requires 120Vac power to terminals 1 and 2, and earth ground wiring to terminal 3. * Then, try turning the power to the ETV Platinum Plus Control Module off and then back on.

Why does the outlet temperature fluctuate with my Heat-Timer ETV Platinum Plus?
- S
  Sarah ThomasAug 20, 2025
  Outlet temperature fluctuations in the Heat-Timer ETV Platinum Plus system typically occur when the circulation pump isn't running constantly or the System Sensor isn't properly placed. Ensure the pump operates correctly, the System Sensor tip is in the flow stream, and the sensor is 1 to 3 feet from the ETV valve outlet.

  If your Heat-Timer Control Unit system reads an incorrect temperature, it might be due to: * A probe sensor that is not properly installed. Ensure the probe sensor is correctly placed in the flow of the water stream. * A defective sensor or ETV Platinum Plus Control Module. Disconnect the wires from the input terminals; the display should then read “Open”. If it doesn't, the device is defective and the ETV Platinum Plus Control Module should be replaced. If the control reads “Open” and the temperature difference is within 5°F, replace the sensor.

  Lisa DennisAug 27, 2025
  If the Heat-Timer Control Unit display shows sensor “Open”, it could be due to: * A disconnected sensor. Verify the sensor is properly connected to the ETV Platinum Plus Control Module. * A defective sensor, wires, or ETV Platinum Plus Control Module. Short the sensor input wires. The display should read “Short”. If the display still reads “Open”, the device is defective and the ETV Platinum Plus Control Module should be replaced. If the display reads “Short”, test the sensor wiring for continuity and replace the sensor/wiring if necessary.

  If the Heat-Timer Control Unit display shows sensor “Short”, it could be due to a defective sensor, wires, or ETV Platinum Plus Control Module. To resolve this: * Remove the sensor wires from the input terminals. The display should read “Open”. * If the display still reads “Short”, the device is defective and the ETV Platinum Plus Control Module should be replaced. * If the display reads “Open”, test the sensor wiring for continuity. Replace the sensor/wiring if necessary.

What to do if Heat-Timer Control Unit display shows IP DUPE?
- W
  William CastilloSep 4, 2025
  If the Heat-Timer Control Unit displays 'IP DUPE', it means two controls have the same IP address. To resolve this, change the second control’s Internet ID to a unique value and configure the Port Forwarding accordingly.

What to do if Heat-Timer ETV Platinum Plus Control Module doesn't move the Floating Motorized Valve?
- R
  rhillNov 11, 2025
  If the Heat-Timer ETV Platinum Plus Control Module isn't moving the Floating Motorized Valve, it could be due to a few reasons: 1. **Valve wiring defective:** Ensure all wiring is in good condition and properly connected. Check that the voltage at the Actuator power terminals is between 20–24Vac. Voltages outside this range can prevent movement or damage the Actuator. 2. **Valve modulating signal incorrect:** Verify the ETV modulating signal is set to 0–10V to match the Actuator’s signal. Use a DC voltmeter to measure the modulation signal on terminals 13 and 15. If the Modulation Output % was at 40%, the signal should read 4Vdc. If not, the ETV control may be damaged, and the ETV Platinum Plus should be replaced. 3. **Actuator manual override engaged:** Make sure the actuator is not s...
