Oasis Heat Command 3 (SLH3) Heat Pump and Gas Heater Controller

🏷️ Brand

Oasis (Sunlover Group)

📝 Description

The Oasis Heat Command 3 (SLH3, SSC012) is a 240V digital pool heating controller that runs a heat pump or gas heater on an independent heating circuit, switching the circulation pump on when heat is needed and stopping at your set temperature limit.

You set the temperature limit and run schedule, and the controller manages the rest, with Standby, Heating and Cooling modes and a "1st HEAT" override for an immediate heat-up. Gas heaters connect through a low-voltage interlock so the heater gets its cool-down cycle (adjustable 0–20 minutes) before the pump stops.

💡 Before You Buy

• Independent system only. This controller runs a separate heating pump. For an Oasis heat pump plumbed in line with the filter pump and chlorinator, look at the Oasis Heat Junction 5 (HJ5).
• Interlock wiring. The interlock is for extra-low voltage only. Connecting mains voltage will damage the controller.
• Mounting. Mount at least 3 m from the water's edge and 600 mm above the ground, and plug straight into a power point, not an extension lead.

❓ Common Questions

• Does a heat pump need the interlock? Usually not. Heat pumps can normally be switched by stopping the water flow. Gas heaters use the interlock so they can cool down first.
• Can it cool my pool? Yes, it has a Cooling mode for heat pumps that can cool.
• Where does the pool sensor go? In the heating circuit before the pump, close to the pool and out of direct sunlight, in the side of the pipe.
