Its control connects to Wi-Fi for the Raymote phone app and can also run valve actuators, a pump and auxiliary pool equipment.

📌 Good to know:

• A heat pump puts out less heat per hour than a gas heater and may run many hours a day to hold temperature. Raypak recommends covering the pool when it is not in use.
• Leave 5 ft of open space above the unit and 1 ft on each side for service, and keep it at least 3 ft from any gas or other fuel-burning heater.
• Chlorinators and chemical feeders go after the heater, with a check valve or Hartford loop between them.
• If the heater sits below the pool water line, the water pressure switch may need adjusting, and Raypak's manual calls for an external water flow switch (kit H000166, not included).
• Electrical connection is for a licensed electrician, and any work on the sealed refrigerant circuit is for a qualified technician.

Gas, venting and electrical work must be done by a qualified installer and meet local codes.
