The CP-RTU-LM controllers provide fan, heating and cooling, damper and air quality control capabilities. Using the Comfort Point LNS plug-in, the controller can be configured with job-specific settings. Both conventional and LCD-Digital wall modules interface with the controllers and provide any or all of the following: SetPoint adjustment within limits, fan speed adjustment, and an occupancy override. All wall modules include a space temperature sensor (20K thermistor). The Fan is enabled by occupancy or unoccupied demand control. The temperature control for heating and cooling control is optional and can be staged up to 3 stages each, or controlled with a 0-10 modulating signal. Cascade discharge-air temperature control can be enabled when using modulating control. Damper Control: The dampers will be controlled to maintain a minimum position and will modulate to control air quality. Economizer control will be sequenced with cooling control when enabled. Temperature control can be selected to control for space or discharge air temperature. Air Quality Control utilizes CO2-level inputs to control the economizer using a minimum position and will override temperature control.
The number of applications for LonMark certification is growing rapidly. To make sure your products are on-track for certification, design conformance into them by following the LonMark Interoperability Guidelines v3.4.
The Proficiency Testing Program for Qualified Open Systems Installers, Professionals and Integrators provides a worldwide standard of proficiency for individuals that install, integrate and maintain systems utilizing LonMark certified products.
