• Check that the pipe system is complete.
• Check the pipe system for leaks.
• Check that the electrical installaon 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 acve
for at least 3 hours before compressor operaon can be
iniated. This is done by connecng control voltage. EAV
permits compressor start aer 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 venng port on the ex tube
(included) and possibly the circulaon pump.
3. See “Flushing and Filling System” for details.

1. Communicaon cable, the EAV 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. Aer 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,
aer max 180 minutes. The length of this me delay
depends on whether the compressor has been warmed
up previously. See chapter Preparaons secon, above.
Preparing Piping System
Air is inially released from the water/anfreeze soluon and
venng may be necessary. If bubbling sounds can be heard
from the heat pump, the circulaon pump and piping/fan coils
the enre 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.
General
EAV is equipped with an internal electronic controller that
handles all funcons necessary for operaon of the heat
pump, e.g. defrost cycle, stop at max/min. temperature,
connecon of the compressor heater, and protecve funcons
during operaon. Temperatures, number of starts and run
me, are displayed in the indoor module/control module.
The integrated control shows informaon via status-LEDs and
can be used during servicing.
Under normal operang condions 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 sengs and measurement
values from EAV are adjusted and displayed on the indoor
module/control module.

The Startup Wizard is part of the First Run Setup. This Wizard
is designed to ensure that the system has the proper ow
rates and that air is purged from this system. Screens from the
Startup Wizard are shown on the following pages.
