Heat Controller MCL012AEC30C0PS Water Source Heat Pump 1 Ton

Product Description

The HEAT CONTROLLER MCL012AEC30C0PS is a 1-ton horizontal water source heat pump designed for both heating and cooling in commercial and residential hydronic systems. Rated at 265 volts single-phase and charged with R-454B refrigerant, this unit delivers a ground water cooling capacity of 12,800 BTU/h at 59 degrees F entering water temperature and a heating capacity of 11,700 BTU/h at 50 degrees F EWT. A coaxial heat exchanger and extended-range refrigerant circuit support efficient heat transfer across a wide range of water temperatures. A built-in performance monitoring system alerts technicians to potential faults before they become failures.

This unit is engineered for horizontal installation in applications where ceiling or cabinet space is limited, making it well-suited for retrofit jobs and tight mechanical rooms. The compact footprint maximizes usable building space without sacrificing output. Left return air configuration supports common horizontal concealed installations in hotels, office buildings, multi-family units, and similar light commercial settings. It exceeds ASHRAE 90.1 efficiency standards, which is relevant for projects subject to energy code compliance review.

Key Features

• Ground water cooling EER of 19 and COP of 3.9 at 59 degrees F EWT
• Water loop cooling EER of 12.7 and COP of 4.5 at 86 degrees F EWT
• R-454B refrigerant with extended-range refrigerant circuit for broad operating conditions
• Coaxial heat exchanger for efficient water-to-refrigerant heat transfer
• Performance monitoring system provides early fault signaling
• Horizontal compact design suited for retrofit and space-constrained installations
• Exceeds ASHRAE 90.1 efficiency requirements

Compatibility

Designed as an OEM-style horizontal water source heat pump for use in water loop and ground water hydronic systems requiring 1-ton nominal capacity at 265 volts single-phase.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with water source heat pump systems, hydronic piping, and low-voltage control wiring. Shut off water supply and disconnect electrical power before servicing or making connections. Follow local mechanical and electrical codes, including applicable ASHRAE and NEC requirements, for refrigerant handling, electrical termination, and condensate drainage. R-454B is an A2L mildly flammable refrigerant and requires certified technicians and appropriate handling procedures per EPA Section 608 regulations.
