Installation Instructions

General information

This hot water coil is factory-installed as
an option.
These instructions give the necessary in-
formation for correct installation at the job
site (see Fig. 1).
Located in the air impulse section, thus
correctly protected against any freezing
problems.
Allows installing the unit for side or upflow
impulse duct connection, even on a roof curb
(standard accessory), without the need for
any further modification.
The control board, cables and all material
necessary for installation are supplied with
this accessory.

Technical specifications

This accessory includes the following com-
ponents:
- Coil: With steel sheet frame, copper tubing
and aluminium fins.
- 3-way valve: Bronze body.
- Electric actuator: 0-10 V, 24 VAC propor-
tional control.
- Control board and plastic partitions.
- Temperature probe for water intake, B17.
- Manual air purger: Accessible from the
outside by means of a cover on the side
panel of the unit.
Installation
As all components are factory-fitted, at the
job site it is necessary to merely connect

the 3-way valve intake and output to the
how water line.
Turn main power supply to the unit off by
means of switch Q1. See Figs. 1, 2, 3, 4, 5 and
wiring diagram for coil assembly details.
Install the coil as follows:
1. Open the access panel to the 3-way
valve.
Remove and discard the interior cover.
Remove and save the side impulse
cover. Once installation is completed,
replace and make sure no screw is left
out.
For units with bottom impulse air duct,
remove and discard the cover on the
base.
For units with side air duct, keep the
cover on the base.
2. The water intake and outlet connections
are carried out either from the front,
in the zone between the impulse and
compressor chamber and the electric
box (Fig. 1).
Attention:
It is recommendable to install manual
valves on the intake and outlet lines, so
as to be able to isolate the unit from the
general installation if necessary.
3. Hot water coil control board.
The control board and the water intake
probe are factory-installed. The wiring of
the valve actuator has also been com-
pleted as per the wiring diagram.
Once the water intake and outlet con-

nections are completed, turn the power
supply to the machine on.
Make sure the green LED (V1) on the coil
control board (A6) is flashing. Accessory
board configured.
Should this not be the case, carry out a
search and configuration of accessories
by pressing the test button on the Yklon
board (A1) for over three seconds, until
the red LED goes on. Once this search
and configuration process begins, the
red LED goes on and stays on until this
operation is completed. Once it goes
off, make sure the green LED (V1) on
the coil board is flashing to indicate the
accessory has been configured.
4. Check valve actuator operation.
A potentiometer, P1, on the coil control
board allows modulating the 3-way valve
manually to check its operation. The
actuator will go back to its operating
position after 30 seconds.
5. Jumper S2 (ENTALP) selection
By defect, factory-set to open, selects
the priority of the compressors in heat
pump models. If closed, selects operat-
ing priority of the hot water coil over the
compressors. Adequate for installations
with very economical hot water.
6. Water pump operation relay output.
The control board has a relay (K1) that,
through connector J14, gives output to a
volt-free contact for the operation of an
installation water pump.
