Beyond “Standard” Expectations

Easy to read LED diagnostics

Sensors in the unit continually monitor the indoor coil,

outdoor coil, and outdoor air conditions. If abnormal

conditions are detected, an error code is displayed,

removing the guess work in troubleshooting a unit.

The hydronic experts

McQuay is a leading manufacturer of hydronic heat

equipment. We specialize in providing hydronic heat

with a host of congurable options.

Modes

● Cooling only mode with hydronic heat

● Cooling only mode with hydronic heat and

supplemental electric heat.

● Top mounted hydronic coil

(steam or hot water)

Controls-with built in hydronic logic

● Normally open/normally closed valve

control

● Heat fan lockout – prevent the fan from

coming on until there is heat in the pipes.

Easy fan motor removal

Electric heat override

Heat pump units can be manually switched to electric

heat, providing added freeze protection if the heat

pump mode is not available due to a compressor

failure.

Compressor protection

The life of the compressor is extended through built

in protection logic such as:

● High temperature protection if the

compressor temperature exceeds 154°F

● Minimum run time

● Minimum off time

● Random restart after a power outage

● Low ambient lockout when the outdoor

air temperature falls below 35°F

Memory recall

Control settings are saved in a non-volatile memory,

allowing the last settings to be recalled after a loss

of power.

Easy installation and service design

Quick link connections

Applied PDAE/PDHE units are designed for easy

access with quick link connections to the control box.

The simple slide in/slide out conguration makes it

easy to access the electric heater, indoor and outdoor

fans, motors, and compressor.

Easy fan removal
