Description

  • Powerful Performance, Lower Startup Current : Soft starter for up to 7 Ton (84,000 BTU) RVAC & HVAC units. Equipped with magnetic latching relays, dual SCR control, Hall detection and cyclic capacitor tech. It delivers gentle startup, reducing startup current by up to 75%, cutting power surges and extending compressor service life.
  • Bluetooth Smart Monitoring & Control: Connect through Bluetooth for real-time system monitoring and easier setup. The smart interface helps detect operating conditions and provides better control over your RV or HVAC soft start system. Please noted bluetooth only functions with the compressor in normal operation. Signal may attenuate from installation‑site obstructions; please keep it close to the HVAC unit.
  • IP6 Waterproof & Heavy-Duty Protection: Built with IP6 waterproof & dustproof enclosure, S72 Pro HVAC soft starter is engineered for demanding outdoor environments including RV applications, protecting internal components from moisture and weather exposure.
  • Intelligent Protection for Compressor Operation: Equipped with advanced current detection technology and intelligent control algorithms, TURBRO AC soft starter helps manage compressor startup load, improve electrical efficiency, and extend AC system lifespan.
  • Engineered for generators, inverters and limited-utility/off-grid power systems, this home AC soft start kit cuts startup current for smooth air conditioner performance under low amperage conditions. It works with 2-stage compressors and heat pump units, ideal for RVs, solar setups, backup power and blackout scenarios.
  • Installation Reminder: Please kindly check and remove original start components before installation. If there are PTCR and START CAP., please remove both. If there are START RELAY and START CAP., also remove both. Otherwise, these components will cause compressor startup failure. Pleas contact us for confirmation before installation if you are in doubt.

Q&A

Q1: Can I install the soft starter by myself?

A1: No, installation must be performed by a qualified electrician.

Q2: Does this soft starter provide overcurrent protection?

A2: No, this soft starter is NOT an overcurrent protection device. It must not be used as a substitute for any primary circuit overcurrent protection system.

Q3: S72 Pro or S15 Plus? How can I choose the right model of soft starter that I need?

A3: The S15 Plus is mainly used for low tonnage units, such as RVAC systems. The S72 Pro works for both low tonnage and high tonnage applications, including RVAC, residential air conditioners, and commercial heat pumps, etc.

Q4: What power sources can this soft starter work with?

A4: The soft starter is designed for off-grid, backup power, and low-amperage systems, allowing your AC to run efficiently even during blackouts or when using generators, RVs, or solar power.

Q5: Why the bluetooth drops connection constantly and when it does connect the readings will freeze or lag?

A5: The Bluetooth signal from the soft starter has an approximate 10‑meter range. For example, if the soft starter was mounted inside an air conditioner, the unit housing blocks part of the signal. If it was installed in an RV, the ceiling creates further obstruction, leaving an effective range of only 2‑3 meters. Bluetooth only works when the compressor runs normally. Obstructions in the installation environment cause signal attenuation; please keep the device close to the HVAC unit.
