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

The Variable Fan & Coil is designed with efficiency and performance in mind to meet ASHRAE 90.1 and AHRI RFC

440. The manufacturing process meets UL 1995 ETL safety standard. Our manufacturing plant is ISO 9001:2015

quality certified.

• Aluminum / Copper coil: Allows for high-efficiency temperature transfer. Long lasting material that is easy to

maintain and repair. Our certified coils are manufactured and tested in-house.

• Centrifugal fans: Sturdy, reliable and silent.

• Electronic 2 or 3 way valve: With smart actuator to control water flow to the coil very precisely to maintain the

injection temperature.

• Programmable digital thermostat: With 5 daily time schedules and humidity sensor. Aesthetic design, easy to

use and multiple programming options.

• Temperature sensors: Analog readings for precise temperature control.

• Condensate tray: Includes anti-bacterial coating.

• Filter Casing: Includes filter holder box, easy access.

CLIFC VARIABLE - INSTALLATION, OPERATION AND MAINTENANCE MANUAL

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”.
