CLIFC VARIABLE - INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Standard features
Current air conditioning systems must comply with two fundamental characteristics: efficiently provide the comfort
required by the users and offer energy savings to reduce the environmental impact and operating costs.
To cope with this challenge Clima-Flex has developed a unit that provides comfort and energy savings at the same
time, the variable Fan & Coil unit available in vertical and horizontal configuration.
The standard features of the Variable F&C are:
It’s capable of operating in the entire range of the fan motor (from 1% to 100%), which allows it to adjust very
precisely to the demand at any given time. Modulating its operation and saving electrical energy.
It reduces moisture significantly during normal operation, even when the unit is in “standby” mode. By reducing the
humidity a more pleasant atmosphere is created for the users and the useful life of the elements of the room are
prolonged (carpet, bedding, wallpaper, etc.)
The equipment is small in size, easy to install, quick and simple to maintain. Low noise level, especially in moments
of low latent heat such as night. Flexible connection configuration (left or right). Configurable control range, with a
variation of less than +/- 1 ° F / ° C. Quick water connections that use flexible plastic hose. Hydronic operation

Operation
The variable Fan & Coil is controlled by a thermostat, the Set Point is defined to reach the desired comfort
temperature. The system performs calculations considering an average between the air injection sensor, the room
sensor and the rate at which the temperature changes, adjusting the operation of the system at different speeds to
satisfy the requested temperature as soon as possible.
As the temperature approaches the “Set Point” the system regulates the fan speed until reaching the desired
temperature, thus saving electrical energy by always operating at the minimum necessary capacity to meet and
maintain the Set Point. The modulating water valve keeps the injection temperature constant by regulating the
chilled water flow.
The Variable F&C reduces the humidity at all times automatically by keeping the temperature of the coil below the
dew point of the room, this causes any humidity present to condense and be removed by the condensate tray.
The entire system increases and reduces the speed of the fan to meet the changes of the demand. The logic of
operation starts from the premise that once the Set Point is reached the demand is lower and the system is not
required to operate at a higher capacity. When the demand (either cooling or heating) begins to decrease, the
system decreases the electricity consumption; because it decreases the energy delivered to the fan. The unit
becomes progressively quieter as it reaches the Set Point, being of special importance during night operation.
When the Set Point temperature is reached, the Variable F&C does not shut down, it keeps operating at a very
low percentage (5-10%) to maintain the temperature, because of this moisture is removed at all times helping to
maintain a more comfortable and healthy atmosphere for the users.
The Variable F&C system performs optimally in installations with a primary water circuit with variable pumping. Due
to its proven results to control humidity this equipment has had great acceptance in: offices, residences, hospital
rooms, banks and any place where temperature and humidity control is needed. The Variable F&C unit operates
under the following principle: “It operates at the minimum capacity required to maintain the set conditions at all times
and adjusts according to changes”.
