EAV - EME/EMD Rev. A Models
Installaon and Operaons Manual
• Check that the pipe system is complete.
• Check the pipe system for leaks.
• Check that the electrical installaon is prepared.
• Check that the electrical supply is connected so that the
compressor crankcase heater can start warming up the
compressor, if necessary.
• The compressor crankcase heater must have been acve
for at least 3 hours before compressor operaon can be
iniated. This is done by connecng control voltage. EAV
permits compressor start aer the compressor has been
warmed up. This can take up to 3 hours.
1. Fill the hydronic system to the necessary pressure.
2. Vent the system using the venng port on the ex tube
(included) and possibly the circulaon pump.
3. See indoor secon installaon for detailed ushing/purging
piping system of air.
1. Communicaon cable, terminal block (X22:1-4) must be
connected.
2. Turn the isolator switch on.
3. Ensure that the EAV is connected to the power source.
4. Reinstall the removed panels and cover.
5. Aer the power to EAV has been switched on and there
is a compressor demand from the indoor module/control
module, the compressor starts once it has warmed up, aer
max 180 minutes. The length of this me delay depends on
whether the compressor has been warmed up previously.
See chapter Preparaons secon, above.
6. Adjust menu sengs via the indoor HMI (touchscreen
Human Machine Interface) as necessary.
7. Fill in the commissioning report.
8. Remove the protecve lm from the cover on EAV.
Air is inially released from the water/anfreeze soluon and
venng may be necessary. If bubbling sounds can be heard from
the heat pump, the circulaon pump and piping/fan coils the
enre system will require further ushing/purging. When the
system is stable (correct pressure and all air eliminated) the
control system can be set as required.
EAV is equipped with an internal electronic controller that
handles all funcons necessary for operaon of the heat pump,
e.g. defrost cycle, stop at max/min. temperature, connecon
of the compressor heater, and protecve funcons during
operaon. Temperatures, number of starts and run me, are
displayed in the indoor module/control module.
The integrated control shows informaon via status-LEDs and
can be used during servicing.
Under normal operang condions the home owner does not
need to have access to the controller.
EAV communicates with the Enertech indoor module/control
module, which means that all sengs and measurement values
from EAV are adjusted and displayed on the indoor module/
control module.
