THERMODYNAMIC HEAT RECOVERY C,D, E, E+BOX - INSTALLATION
REFRIGERATION CIRCUIT
Frigorific components access:
Compressor is located in the fix condenser part. Its access for electrical checking and
pressure taps (HP and LP) is made through the screwed access door behind the hinged
coil.
4-way valve, thermostatic expansion valve, dryer, and sensors are located on the e-
Drive™ supply compartment.
Electrical components:
• For D and E-box, specific TRMO components are located in the electrical box.
• For C-box, specific TRMO components are located on the back of the electrical box, and can be accessible from the
supply e-
Drive™ compartment.
COMMISSIONING
Electrical connections:
• All wire connections are factory made.
Starting up:
•
CLIMATIC™ configuration:
o
Power the unit
o
Check the configuration of the CLIMATIC™ with the DS in expert mode.
•
Flow rate settings:
Make sure that both supply and exhaust air flow are balanced. See section EBHO or ERVF. Balancing is correctly set if:
o
with Test = 'B.Nom 100%': at 100% fresh air, set the exhaust Flow 3864 = supply flow 3333;
o
then switch Test = 'B.Nom 0%':
▪
reduce coefficient 3866 until the louvers are closed;
▪
then if the flow (supply and exhaust) is far from the previous flow settings, set coefficient 3335;
▪
finally, repeat step 1 and 2 to obtain a constant flow whatever the fresh air mode.
o
same settings have to be realized for reduced flow - 3334 and 3865.
WARNING! During the settings, wait until the economizer is fully closed or opened, since it takes 1-2 minutes to switch.
•
Start the TRMO circuit (circuit 3): switch Test='C3--Cool'
o
check the sense of rotation of the circuit 3 compressor;
o
check frigorific values (HP, LP, overheating and subcooling).
•
Repeat the last operations with Test='C3--Heat'
