1.
With the key
on the control modules, select HEAT mode
and then set the maximum
temperature with the UP and DOWN arrows. The ambient temperature should be within the
operating limits (Refer to the §
, page 7). In the same way, during the pre-
commissioning checks the exchanger pump(s) water loop inlet temperature should be within the
limits corresponding to each operating mode (Refer to the §
, page 7).
Reminder: if one of these factors is situated at its minimum or maximum level, the other should be
situated at a normal level in order to ensure the unit’s correct and normal operation.
2.
Ensure that the thermostat is connected properly and set the set temperature above the ambient
temperature of the zone to be cooled. After 3 minutes, the compressor starts operating.
3.
When the appliance has been operating for a few minutes, check the presence of hot air at the
blowing grille.
4.
When the appliance has been operating for a few minutes, check the temperature of the unit’s outlet
water. Generally, this should be around 3°C below the unit’s water loop inlet temperature. A variance
lower than 2°C indicates that the water flow is too high, whilst a variance higher than 6°C indicates
that the water flow is too low.
5.
Adjust the isolation/balancing valve on the outlet water pipe to obtain the appliance’s nominal water
flow (Refer to the Maker’s Plate)
6.
Check for the absence of vibrations and water leaks.
7.
When all the above tests have been completed, adjust the system to maintain the desired comfort
level.
After performing all the above-mentioned checks, proceed with creating a demand for Cooling and Heating
or vice versa.
18.1. COMMISSIONING
18.1.1. DEMAND FOR COOLING
1.
With the key
on the control module, select COOL mode
and then set the minimum
temperature with the UP and DOWN arrows. The ambient temperature should be within the
operating limits (Refer to the §
, page 7). In the same way, during the pre-
commissioning checks, the exchanger pump(s) water loop inlet temperature should be within the
limits corresponding to each operating mode (Refer to the §
, page 7).

situated at a normal level in order to ensure the unit’s correct and normal operation.
2.
Ensure that the thermostat is connected properly and set the set temperature below the ambient
temperature of the zone to be cooled. After 3 minutes, the compressor starts operating.
3.
When the appliance has been operating for a few minutes, check the presence of cold air at the
blowing grille.
4.
When the appliance has been operating for a few minutes, check the temperature of the unit’s outlet
water. Generally, this should be around 5°C above the unit’s water loop inlet temperature. A variance
lower than 3.5°C indicates that the water flow is too high, whilst a variance higher than 8°C indicates
that the water flow is too low.
5.
Adjust the isolation/balancing valve on the outlet water pipe to obtain the appliance’s nominal water
flow (Refer to the Maker’s Plate)
6.
Check that the condensates drainage system is working properly and check that a siphon is included
in the drainage line.
7.
Check for the absence of vibrations and water leaks.
8.
When all the above tests have been completed, adjust the system to maintain the desired comfort
level.
18.1.2. DEMAND FOR HEATING
Note:
If the unit does not operate, perform a fault diagnosis (Refer to the §
page 27). If the fault analysis does not enable the cause of the problem(s) to be determined or if the unit
still does not operate, contact a qualified after-sales technician to obtain a correct diagnosis and to repair
the equipment.
