Buy McQuay Circuit Board Parts

McQuay Circuit Board, like the Mark IV/AC circuit board, equipped with the new MicroTech 2000 Source Heat Pump Controller are a part of the McQuay® Enfinity (R-410A) and Standard (R-22) Horizontal source heat pumps. The R-22 and R-410A refrigerants are used in the various models

The Mark IV/AC circuit board comes as an option and can be installed only if required. This control system comes with built-in features such as compressor time delay, load shed, random start, night setback, shutdown, condensate overflow protection, brownout, LED outputs for fault detection and defrost cycle. This control is designed to work with a 24 volt wall thermostat which is a 24 volt or a microelectronic wall thermostat. Each control has a printed circuit board control system.

The Mark IV/AC control board stops the compressor from operating if there is a safety issue by making use of its lockout circuit. The circuit also has a remote reset feature which is used to reset remotely any automatic lockouts which have been caused by faults due to high-pressure or low-temperature (in heating). Every Enfinity R-410A and standard R-22 horizontal source heat pump can be optionally equipped with a MicroTech 2000 source heat pump controller. The Microtech comes with sensors for temperature. This controller is linked to the centralized building automation system.

Enfinity Vertical Source Heat Pumps

This equipment is designed for indoor installation only. The Mark IV/AC circuit board is an optional control system with built-in features such as random start, compressor time delay, night setback, load shed, shutdown, condensate overflow protection, defrost cycle, brownout, and LED/fault outputs. The has been designed for operation with a 24 volt mercury bulb type wall thermostat or a microelectronic wall thermostat selected by the manufacturer.

Each Enfinity vertical source heat pump can be equipped with a MicroTech 2000 source heat pump controller. The controller is microprocessor-based and is designed to communicate over a LonWorks communications network. The controller is factory programmed and tested with all the logic required to monitor and control the . The controller sets the mode of operation, monitors and air temperatures, and can communicate fault conditions to a LonWorks communications network.

The MicroTech 2000 controllers include -mounted return air, discharge air and leaving temperature sensors. Options include a tenant setpoint adjustment knob and tenant override button, and the capability of substituting the return air sensor with a wall-mounted room sensor.

MicroTech 2000 heat pumps are designed to be linked with a centralized building automation system through a LonWorks communications network for centralized scheduling and management of multiple heat pumps. Wall-mounted room sensors are available to control the heating and cooling operation of each MicroTech 2000 Source Heat Pump Controller. Available room sensors include: room sensor with LED status and tenant override button, room sensor with LED status, timed-override button, and bi-metal thermostat; room sensor with LED status, timed-override button, and setpoint adjustment; and room sensor with LED status, timed-override button, setpoint adjustment and bimetal thermostat.

Enfinity vertical source heat pumps are available with a factory mounted and tested Alerton BACnet controller as a special.
