Heat Controller MCL018AEC30C0PS Heat Pump 1.5 Ton 265V

Product Description

The HEAT CONTROLLER MCL018AEC30C0PS is a horizontal water source heat pump rated at 1.5 nominal tons and designed for single-phase, 265-volt electrical service using R-454B refrigerant. This unit delivers both heating and cooling through a coaxial heat exchanger that transfers energy between the refrigerant circuit and the water loop or ground water source. The compact horizontal profile is engineered to minimize footprint, making it well suited for ceiling plenum spaces, mechanical closets, and retrofit projects where clearance is limited. A built-in performance monitoring system detects abnormal operating conditions and signals potential faults before they escalate. Licensed HVAC technicians familiar with hydronic or geothermal systems are the primary installers of this equipment.

This unit is designed for commercial and residential applications where a building water loop or ground water source is available. The horizontal configuration fits above dropped ceilings and in tight mechanical spaces common in multi-family, hospitality, and office retrofit projects. The extended-range refrigerant circuit allows the unit to operate efficiently across a wide entering water temperature range. Ground water performance is rated at 59 degrees F entering water temperature for cooling and 50 degrees F for heating. Water loop performance is rated at 86 degrees F EWT for cooling and 68 degrees F EWT for heating. The left return air configuration suits common horizontal installation orientations.

Key Features

• Coaxial heat exchanger for efficient water-to-refrigerant energy transfer
• R-454B refrigerant with extended-range circuit for broad EWT operating capability
• Exceeds ASHRAE 90.1 efficiency standards
• Ground water COP of 4.2 and EER of 23 at 59 degrees F EWT
• Water loop COP of 4.9 and EER of 14.3 at rated loop conditions
• Performance monitoring system provides early fault indication
• Compact horizontal form factor designed for tight spaces and retrofit applications

Compatibility

Designed as an OEM water source heat pump for single-phase 265-volt building water loop and ground water hydronic systems requiring a 1.5-ton horizontal unit with left return air configuration and R-454B refrigerant.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-454B refrigerant under applicable EPA Section 608 regulations. Shut down the building water loop and disconnect electrical power at the disconnect switch before servicing or connecting the unit. Verify supply water flow rate and entering water temperature are within the equipment operating range before startup. Follow local mechanical and electrical codes, including applicable ASHRAE and NEC requirements, for refrigerant piping, electrical connections, and equipment support.
