Dynamic set point and suppression of buffer
tank

The YLCA/YLHA PLUS 5 to 27 control system has Dynamic
Set Point and Suppression of Buffer Tank functions.
Dynamic Set Point. Modifies water temperature control set

point in accordance with the outdoor temperature. The pur­pose of this is to avoid excessive an temperature differential
between the indoor and outdoor air conditioned areas. If this
differential is excessive, it could cause discomfort and thermal
shock that could be detrimental to the health of the users en­tering and leaving this area. On the other hand, this function,
that increases the set point in winter cycle and lowers it in
summer cycle, contributes considerably to saving energy.
Suppression of Buffer Tank. This function increases the
temperature differential that, added to the control set point,
controls the on/off cycles of the compressor when the unit is
operating at a low charge. To achieve this, the reference point
used is the duration of the compressor operating cycles. In
this way, when the water temperature falls quickly, it delays the

Technical Specifications

These units are supplied completely factory-assembled and
with all refrigerant tubing and wiring ready for installation on
the job site. After installation, these units must go through
an operational test with water. Refrigerant leaks will also be
checked during this process.

Sheeting casing

The units are made of galvanized steel sheeting and anticor­rosion nuts and bolts. Panels can be removed for access to
internal components. The casing parts are painted with white
RAL9001 oven-baked polymerized enamel.

Compressor

Hermetic Scroll compressors mounted on antivibratory
supports are used. These compressors are equipped with
electronic modules that protect them against high operating
temperatures. The sump heater operates (units only 20 to

27) only when the compressor is inoperative.

Indoor heat exchanger

Comprises a stainless steel plate exchanger, adequately
insulated by a layer of closed-cell elastomer foam. The refrig­erant side of said exchanger accepts an operating pressure of
52 bar, whereas the water side accepts 10 bar. When the unit
includes a hydro kit, maximum admissible pressure on the
water side is 6 bar (adjustment of the relief valve).

Outdoor heat exchanger

Made up of notched blue fin aluminium, fin coils and grooved
copper tubing mechanically expanded within the fin assembly.

Fans

Of the axial and low sound level type. Equipped with single­phase motors with IP54 protection. These motors allow speed
control by means of a phase cut-out shifter controlled by
the unit controller. This allows unit operation at low ambient
temperatures (-10°C).
An optional low ambient temperature kit (pressure sensor)
can reach -18°C. This kit is included as standard on heat
pump models YLHA PLUS. On heat pumps, the fan will remain
inoperative during defrosts.

Electric and control panel

Located inside the unit, and with IP44 protection. The operat­ing and control components are factory mounted, wired and
tested. This control panel is equipped with a locking isolator
that turns power supply off. Inside we find the contactors for
the compressor and the pump, the transformer, magneto­thermal protector, speed control, connecting strip and the
keyboard-display with the unit controls.

Control keyboard-display

This device is accessible through an external leak-tight plastic
cover. This is an easy-to-use control with three access levels:
Direct, User (password) and Factory (password). For further
information, please see Operating Instructions.

of a hydro kit. This assembly is located within the unit frame
and does not increase the footprint of same. It includes the
following components: Centrifugal pump, expansion vessel
charged with nitrogen at 1.5 bar, relief valve set to 6 bar, flow
switch, air bleed valve and drain connection. Also includes
a mesh filter for the water circuit. This filter is supplied loose
for installation at the most convenient point.

Protecting grids

To protect the coils from possible impacts. Made of steel
rods and painted with oven baked polymerized white enamel
(RAL9001).

Low ambient temperature kit (YLCA 5 to 15)

Includes a pressure transducer for controlling condensing
pressure at low ambient temperature (-18°C).
Standard on models YLCA 20 & 27, and YLHA PLUS 5-27.

High pressure fans

Buffer tank

With a backup heater installed.

Antivibratory supports

Whenever necessary to reduce to a maximum vibrations
and noise caused by the unit, you can use a set of caoutch
antivibratory supports, that should be installed between the
supporting chassis of the unit and the base or floor on which
same should be set. This base should be solid and dimen­sioned in accordance with the weight to be supported. To
fasten the supports to the base of the chassis, 8/10Ma screws
are used. The antivibratory supports accessory includes 4
parts. These supports should be distributed amongst and
fastened in the drilled holes in the base, the location of which
is detailed in the General Dimensions section.

Cooling cycle

The 4-way valve is activated. Heat exchange takes place
between the heat transfer liquid (water or glycol water) and
the refrigerant in the plate heat exchanger. Water is cooled,
and refrigerant is evaporated and reheated. Then the Scroll
type compressor condenses the refrigerant (gas) until the con­densing pressure is reached, and the refrigerant goes to the
air cooled condensing unit. In the air cooled condensing unit,
heat is exchanged between the air and the refrigerant. The air
is heated and evacuated from the chiller (heat rejection). The

refrigerant is condensed and sub-cooled. Then the refrigerant
(liquid) goes on to the expansion valve, where it is expanded
until the evaporating pressure is reached, at which time it goes
to the evaporating unit to start a new cooling cycle.

Heating cycle

The cycle is reversed to heating mode. The 4-way valve is
not activated. The condensing unit becomes the evaporating
unit, and the evaporating unit becomes the condensing unit.
The water in the heat exchanger is heated.

Heat exchange takes place between the heat transfer liquid
(water or glycol water) and the refrigerant in the plate heat
exchanger. Water is cooled, and refrigerant is evaporated
and reheated. Then the Scroll compressor condenses the
refrigerant (gas) until the condensing pressure is reached,
and the refrigerant goes to the air cooled condensing unit. In
the air cooled condensing unit, heat is exchanged between

the air and the refrigerant. The air is heated and evacuated
from the chiller (heat rejection).
The refrigerant is condensed and sub-cooled. Then the
refrigerant (liquid) goes on to the expansion valve, where
it is expanded until the evaporating pressure is reached,
at which time it goes to the evaporating unit to start a new
cooling cycle.

Selection guide (YLCA and YLHA PLUS)

Necessary information

The following information is needed to select a YLCA water
chiller:

1. Cooling capacity needed.

2. Design cold water input and output temperatures.

3. Design water flow, if any of the temperatures in above
point 2 is unknown.

4. Design input temperature of air to the condensing unit.
Normally, this will be the design ambient temperature of
summer air, unless influenced by the situation or other
factors.

5. Altitude above sea level.

6. Design gumming coefficient of the evaporating unit.

Taking a quick look at Table 1 we can see that a YLCA-5 unit
gives an approximate required capacity of 5.38 kW.
As the factors appearing in Tables 10 and 11 are not appli­cable, conditions will be as follows:
Cooling capacity: 5.38 kW
Power consumed: 1.87 kW
Water temperature: 13° C to 7° C (∆t = 6)

5.38 x 860

Water flow: = 771 l/h

6

Available pressure in hydraulic circuit of a unit.

- From Table 6 we infer that the YLCA - 5 MC, with a 771 l/h
flow, has an available pressure of 56 kPa.

Note: Points 1, 2 and 3 should be related by means of the
following formulae:

l/h cold water x °C differential
Cooling capacity kW =
860

Selection example

A chiller is required to chill water from 13° C to 7° C, with a
cooling capacity of 5 kW.

Here are other design conditions:

Ambient air entering the condensing unit: 35° C
Gumming coefficient: 0.044m2 °C/kW
Altitude: At sea level

- From Table 7. 1" filter, we infer that with a 771 l/h flow, said
filter has a pressure drop of 1.3 kPa.

YLHA PLUS selection method

1. Determine the correct size of the YLHA PLUS unit by

selecting a model from Tables 3 and 5 that is closest to
the cooling and heating capacities required in the design
conditions of the water outlet and air intake tempera­tures.

2. Apply gumming correcting factors (Table 10) and altitude

(Table 11) to the capacity and power values that appear
in the corresponding capacity tables in cool and heat.
Make sure the corrected capacity is still sufficient for your
needs.

3. Using the corrected capacities of the unit, select the de-

sign temperature differential, or the flow.

4. Check to make sure that these selections are within the

YLCA/YLHA PLUS operating limits.

YLHA PLUS selection example

A YLHA PLUS 5 heat pump operating at a 35° C ambient
temperature should chill water from 13° C to 7° C, with a
5 kW cooling capacity.
A 4 kW heating capacity is required in 0° C design ambi­ent temperature and a hot water output temperature of
45° C.
The gumming coefficient is 0.044 m² °C/kW, with the unit
operating at sea level (no corrections).
With a quick glance of capacity Tables 3 and 5, we see that
a YLHA PLUS 5 heat pump gives the approximate required
capacities:

Altitude (m) Capacity factor

0 1.000 1.000

600 0.987 1.010

1 200 0.973 1.020

Comp. absorbed

power factor

Cooling capacity = 5.40 kW
Total unit absorbed power = 1.91 kW
Cold water temperature = 13° C to 71 C (∆t: 6° C)
Hot and cold water flow = 774 l/h
Heating capacity = 4.15 kW
Total unit absorbed power
in heat mode = 1.88 kW
Hot water output temperature = 45° C
Hot water temp. 4.15 x 860
differential = = 4.60° C

Thus. hot water return
temperature is = 40.4° C

All values are within operating limits.

- Available pressure in hydraulic circuit of a unit with hydro
kit.

- From Table 6 we infer that the YLHA PLUS 5, with a

748 l/h flow, has an available pressure of 56.5 kPa.

- Pressure drop in filter.

- From Table 7.1" filter, we infer that with a 748 l/h flow,

said filter has a pressure drop of 1.2 kPa.

Selection guide with glycol (cool only units)

Necessary information

The following information is needed to select a YLCA water
chiller:

1. Cooling capacity needed.

2. Design cold water/glycol input and output temperatures

to and from the condensing unit.

4. Always recheck to make sure these selections are within
the specified design operating limits.

Selection example

A chiller is required to chill ethylene glycol from 1 to -4° C,
with a capacity of 3.5 kW.

The following design conditions are applicable:
Gumming coefficient: 0.088m² °C/kW
Altitude: 1 200 m
Ambient air: 30° C
Concentration of glycol: 30% w/w

For a -4° C ethylene glycol output, the concentration recom­mended in Figure 1 is 30%. Therefore, the specified concen­tration is appropriate.

3. Design water/glycol flow.

4. Design input temperature of air to condensing unit.
Normally, this will be the design ambient temperature of
summer air, unless influenced by the situation or other
factors.

5. Altitude above sea level.

6. Design gumming coefficient of the evaporating unit.

Note: Points 1, 2 and 3 should be related by means of the
following formulae:

 ∆t (°C) x Flow (litres/second)
Capacity (kW) =

Glycol factor

In which ∆t = liquid intake temp. - liquid output temp.

To determine the glycol factor, please see Figure 1 for eth­ylene glycol, or Figure 3 for propylene glycol. For design
output temperature, please see the recommended glycol
concentration and the glycol factor in this concentration. This
is the minimum concentration to be used for design output
temperature. If a greater concentration is required, the glycol
factor can be determined by means of Figure 2 on ethylene
glycol or Figure 4 on propylene glycol.

Selection method

1. Determine the correct chiller model by selecting the one
that is closest to the capacities required by the design con­ditions of the glycol outlet and air intake temperature.

2. Apply the gumming correcting factors that correspond to
the gumming coefficient, altitude and glycol concentration,
and to the capacity and power values that appear in the
corresponding capacity tables. Make sure the corrected
capacity is still sufficient for your needs.

3. Using the corrected capacities of the chiller, set the design
temperature range, or the flow, to balance the formulae
appearing in the "Necessary Information" section.

From Table 2 (capacities with 35% glycol) we infer that a
YLCA - 5 unit, at the established design conditions, gives a
capacity of 3.44 kW and a consumption of 1.35 kW.

With the design gumming coefficient, use the capacity cor­recting factors x 0.987 and power x 0.995 (Table 10).

On design altitude, apply the capacity correcting factors x

10.973 and power x 1.020 (Table 11).

On design glycol concentration, apply the capacity correcting
factors x 1.015 and power x 1.005 (Table 3).

Applying these factors to the selection: YLCA - 5

Capacity = 3.44 x 0.987 x 0.973 x 1.015 = 3.35 kW

Comp. power = 1.35 x 0.995 x 1.020 x 1.005 = 1.37 kW

For the specified glycol concentration and a -4° C output
temperature. Figure 3 shows a 0.248 glycol factor. Thus, the
flow can be determined with the formula appearing in the
"Necessary Information" section.

(1 - (-4)) x Flow (l/s)

3.35 kW =

0.248

3.35 x 0.248
Flow = = 0.166 (l/s) or 598 (l/h)
5

This covers the limits of use.
The evaporating unit pressure drop can be determined by
taking the water pressure drop value (Table 7) for a YLCA
unit and multiplying it by the correcting factor (see Fig. 5)
for a 30% concentration and an average temperature of

-1.5° C, that is to say 1 + (-4)
= -1.5

Wiring

WARNING

Electrical connections

All established national regulations should be complied.
Each unit is supplied with a control box to which the power
supply will be connected through a fused main switch or an
automatic switch.

Loose cables can cause overheating of terminals or incorrect opera­tion of the unit. Fire hazards may also exist. Therefore, make sure
all cables are connected firmly.

Rotational direction of Scroll compressors

The Scroll compressors operate correctly in one single rota­tional direction. Although these units are protected by a phase

order detector, when starting the equipment make sure the
rotational direction is correct.
If it is not correct:

- The compressor does not compress.

- It makes a strange sound.

- Amperage consumption is limited.

- It overheats in excess.
The phase detector should have the led son for operation
to be correct.

- Green led on means: Power ON.

- Yellow led on means: Relay ON.

Hydraulic connections

The hydraulic connections of the water intake and outlet of
the unit should be carried out respecting the intake and outlet
directions indicated.
A galvanised iron or copper tubing can be used, with dimen­sions no lower than those indicated, and keeping in mind
the pressure drops at said connections and in the internal
exchanger of the installation.
During the winter season, with outdoor temperatures below
0° C, take precautions to avoid freezing of the water in the
tubing network.
Usually, a solution is filling the circuit with an antifreeze
mixture (glycol).

(Rev. 1016)

Control unit description

This is a multipurpose controller specially programmed for
use with air-water chillers and heat pumps equipped with a
compressor with one single power stage.

Main functions

- Water temperature control (at intake or outlet, as per pa­rameter r6).

- Defrost cycle management.

- System operating and safety management.

- Fan speed control.

- Alarm management.

- Connection for supervision and telephone assistance (ac­cess serial connection RS485).

Devices controlled

- Compressor

- Fans

- Four-way valve

- Water pump

- Alarm device

- Auxiliary heater

Standard components

- Control module. This is the central nucleus that processes
the signals coming from the probes and protection elements
of the entire system to control its active elements: compres­sor and fans, four-way valve, water circulating pump, alarm
relay and auxiliary heater. Power supply 24 Vac.

Can also be used for access and control of the system by

means of the display, buttons and LEDs available. Allows
selection cool, heat and off functions. Operating parameters
can also be modified, and the system can be supervised
as well.

- Fan speed control module. Operates by phase cut-off.
Includes fuse.

- NTC and ratiometric (pressure) probes.

YLCA/YLHA PLUS 5 to 15 standard.
4 NTC probes are used to read system temperatures:
B1. Controls set point. Reads water temperature at ex-

changer intake.

B2. Antifreeze control. Reads water temperature at ex-

changer discharge.

B3. Fan speed and defrost cycle control. Reads refrigerant

temperature inside the coil.

B4. Dynamic set point control. Reads outdoor air tempera-

ture.

YLHA PLUS, YLCA 20, 27 and YLCA 5-15 LAK (low tem-

perature kit).

3 NTC probes are used to read system temperatures and

a ratiometric pressure transducer (B4) to read refrigerant
pressure inside the coil:

B1. Controls set point. Reads water temperature at ex-

changer intake.

B2. Antifreeze control. Reads water temperature at ex-

changer discharge.

B3. Controls dynamic set point. Reads outdoor air tempera-

ture.

B4. Fan speed and defrost cycle control. Reads refrigerant

pressure inside the coil.

Parameters

The set of parameters that configure the operating program of
the unit is divided into four levels (Factory, Super User, User
and Direct), depending upon the function of each parameter
and the user’s access level. The parameters of each level
can be modified from that same level, as well as lower level
parameters.

Factory level

Accessible with the Factory password. Allows configuration
of all unit parameters.

Super User level

Accessible with Super User password. Allows setting Super
User, User and Direct parameters.

User level

Accessible with password 22. Allows access to all parameters
the user normally sets.

Direct level

Accessible without a password. Allows reading the values
detected by the probes, as well as other system values. Can
be used by the user without affecting unit operation.

General

Modification of the parameters that affect basic unit configura­tion should be made with the controller in Standby position.

4 operating modes can be selected in accordance with the
value given to parameter H5. H5=0 (pump disabled), H5=1
(pump permanently on), H5=2 (pump on controlled by the
regulator or in parallel with the compressor), H5=3 (pump
starts and stops at regular intervals, independent of compres-

sor operation) (parameters c17 and c18).

Calibration of probes

If necessary, probes can be calibrated by using parameters /13,
/14, /15, and /16, See Parameters related to probes table.

Remote ON/OFF

A remote ON/OFF intake can be connected between termi­nals D5 and B of the connecting strip. To activate said intake,
a value of 1 should be given to parameter H07 (H07= 1).
With this intake open the unit is OFF; when closed, the unit
is ON. This function does not disable the ON/OFF function
of the keyboard.

Remote COOL/HEAT

A remote COOL/HEAT intake can be connected between
terminals D2 and B of the connecting strip. To activate said
intake, a value of 1 should be given to parameter H06 (H06=

1). With this intake open the unit is in HEAT; when closed, the
unit is in COOL. This function does not disable the COOL/
HEAT function of the keyboard.

Remote terminal

This accessory allows remote control and supervision of the
air conditioning unit (up to 1040 m.). Functions are the same
as the standard control panel keyboard. This remote terminal
is compatible with said keyboard, and the air conditioning unit
can be accessed from both devices. For this application, it
must be connected to the system by means of the RS485

serial line connection accessory.

Wall-mounting

For wall-mounting, the rear support (A) must be fastened to
a standard three-switch modular box.

- Fasten the rear of the casing to the box by means of the
two round head screws.

- Connect the telephone cable.

- Lean the control unit on the rear casing and fasten by
means of the two flat head screws (B).

- Fasten the front panel by applying slight pressure.

Wiring

Connect the RS485 serial device (separate accessory) to the RJ12 power supply outlet (included with the remote terminal)
and to the electric panel keyboard supervising connection, by using shielded cable. Power terminals G-G0 by means of a
transformer and a 250mAT fuse as per the diagram enclosed. Carry out connection between power supply RJ12 and the
remote terminal, using the telephone cable supplied (80 cms.). This cable can be replaced by a longer cable of up to a
maximum of 40 m.

Attention:

- Use safety transformers only (3VA, class 2).

- For safety purposes, a 250mA slow fuse should be inserted in series with the G terminal.

- Do not ground transformer secondary.

Maximum distance to RS485 1 km. (insert a 120-ohm 1/4W resistor in RS485)

Installation

No configuration is necessary for the remote terminal to be operative, because the terminal operates whatever the control
serial direction might be (can be selected by means of parameter H10). At start-up, the screen will display the control ver­sion. After 4 seconds, all symbols will be displayed. Should the connection to the RS485 not be correct, or the control unit
is set to OFF, the message offline is displayed.

Info mode

Pressing the up, down and sel keys simultaneously for over 6 seconds, four lines are displayed with information on the
system and communications.
