The Power and Control Module (PCM) is a direct digital controller designed for pressurized underfloor plenum cooling and heating zones, specifically for interior and perimeter applications. It offers advanced zone control by combining the accuracy of direct digital control with the flexibility of an individual zone control system, aiming for maximum control and efficiency. The PCM comes in a rugged galvanized enclosure, complete with a 100VA transformer and a disconnect switch.
The PCM controller is an advanced and fully configurable underfloor ModuFlex cooling controller. It can be interfaced with one of four Price Thermostats to determine room load and allow for setup functions. With a variety of output configurations, the PCM can control up to 30 underfloor dampers, as well as auxiliary equipment using its auxiliary 24VAC binary outputs, and analog 0-10V outputs.
In cooling mode, an increase in space temperature causes the controller to regulate the dampers open, increasing the flow of cool air. If the space temperature exceeds the proportional band, the dampers' positions are maintained at their pre-selected maximum setting. Conversely, a decrease in space temperature causes the dampers to close, reducing cool airflow.
For heating, if connected to LFGH floor grills with integrated damper and reheat, the PCM will energize or modulate the heat proportionally to the room demand. If the space temperature drops below the proportional band, the dampers' positions are maintained at their pre-selected minimum setting.
The PCM can also be configured to accept 0-10V input signals from a BAS system or a third-party thermostat for room load calculations, instead of data from the thermostat. It can operate as a standalone unit or be interfaced into a BAS with the MS/TP BACnet network.
The PCM offers five thermostat options, providing control from room temperature sensing to motion sensing. The LCD Thermostat allows for balancing and system setup. The LCD Thermostat with Motion can also function as a motion-occupied zone and lighting controller, offering different levels of sensitivity while retaining all standard LCD Thermostat functions.
