General Information
About Fan Coils
Vertical stack fan coil units are used in many high-rise HVAC applications. They deliver excellent comfort to individual zones allowing suite
owners to select their own comfort settings.
Fan coils consist of two critical components – a fan and a coil. The hot or cold water in your coil conditions air to be warm or cool. The fan
circulates air in your suite. The fan draws air in through the access panel in your suite and redistributes air through wall-mounted grilles.
DO NOT block the supply or return air grilles in any way, including with furniture.
The thermostat controls all fan coil features. You can change temperature settings and switch between heating and cooling. The fan has
3 speeds and an automatic setting that you can control as well.

Building Integration
Your vertical fan coil unit integrates with your building-wide hot/cold water system. A boiler and/or chiller, heats or cools water that’s run
through the coil in your fan coil with an extensive pipe network.
Buildings can be equipped with 2-pipe systems for heating or cooling capabilities.
This means your building will switch from heating to cooling and back again. Your
unit senses the water temperature so it will not provide heating if hot water is not
present. Similarly, it will not provide cooling if cold water is not present.
Some buildings have 4-pipe systems for year-round heating and cooling.
If there is an issue with your heating and cooling, it may be caused by the
building’s system.
Your Fan Coil Model
Your Unilux CRFC retrofit fan coil is designed to be installed within the original
HVAC framework. Your retrofit fan coil is manufactured to match the original
heating, cooling and ventilation capacities of your HVAC system.
Drain Pan Overflow Sensor
While cooling, the warm humid air from your suite causes water to condense on the
cold coil. This condensate water accumulates in a drain pan connected to a building
drainage system.
Sometimes condensate water will not drain properly. The drain-pan overflow sensor
on your unit detects when the water level is too high and turns off the flow of cold
water to the coil and stops the fan.
