USER MANUAL
100% GEOTHERMAL HEAT
Use the button in the bottom left corner to return to the home screen. Use the arrow button in the bottom right corner to return to previous screen. For
instructions screen, press the ‘i’ button in the top right corner. In case of operation faults, an alarm button is displayed on the top bar.
process operation temperatures remain as low as possible, which
improves the system’s annual efficiency. Division of the coil into two
parts allows heating of the domestic water circulation only using the
upper storage tank coil, so that blending of the storage tank temperature
stratifications is avoided.
Lämpöässä ESi/EMi/ELi are well suitable for pieces of real estate with
especially high hot domestic water consumption. In renovated residential
buildings Lämpöässä Esi/Emi can be connected to existing separate sto-
rage tank as well if the storage tank is in good condition and is suitable
for geothermal heating. In this case Lämpöässä ESi/EMi/ELi can be con-
nected without the superheating feature and separate storage tank is
used. In case the building includes previously installed water tank that is
suitable for geothermal heating, it can be connected to Lämpöässä ESi/
EMi/ELi.
2.2. ÄssäCooling cooling system
A passive cooling system can be installed into the heat collection circuit,
in which case the fluid in the circuit is circulated through an additional
heat exchanger. The heat exchanger releases cooling energy to indoor air.
Such exchangers include radiant cooling units provided within the venti-
lation system or fan coils installed indoor. Lämpöässä offers multiple
solutions for control of the cooling with ÄssäControl control system.
These are available as accessories.
The Lämpöässä product family includes wall and ceiling-mounted fan
units for cooling, complete with installation set. Passive cooling is a
favourable approach to cooling, since the only running costs are associ-
ated with water circulation pump and cooling fan operation. In Esi/Emi
series cooling is connected externally to the device through heat collec-
tion circulation.
3. How to use the equipment
3.1. Control system functioning
ÄssäControl by Lämpöässä is a logic-based control system. It considers
the conditions prevailing in the premises and the surrounding environ-
ment with improved precision. ÄssäControl control system adjusts the
heating network supply water temperature proceeding from the storage
tank and outdoor temperature based on a seven-point adjustment curve,
so that the room temperature remains pleasantly even regardless of out-
door temperature variations.
Depending on the connections, the control system controls 1-3 heat
distribution circuits or 1-2 heat distribution circuits and domestic hot
water temperature. With the help of the ÄssäControl control system, it is
also possible to control a heat source external to the geothermal heat
pump unit.
These instructions contain a user manual and a manual for equipment
installer. Maintenance functions are password-protected.
3.2. Touch screen functioning
After unit start-up the display goes into basic mode, displaying on the
two-part ÄssäControl home screen function shortcuts (8 pc.), time, date,
and outdoor temperature. To switch between the two home screens, use
the arrow buttons in the bottom right corner. To access the Functions
screen, press the symbol in the top left corner.
