Procedure for space heating/cooling
1 Check the leaving water and entering water temperature through
the remote controller read-out mode and write down the
displayed values. See "Temperature read-out mode" on
page 24.
2 Select the operation mode: heating or cooling.
3 Push the button 4 times so the icon will be displayed.
4 Perform the test as follows (when no action is performed, the
remote controller will return to normal mode after 10 seconds or
by pressing the button once):
To test the space heating/cooling operation push the button
to start the test run operation.
5 The test run operation will end automatically after 30 minutes or
when reaching the set temperature. The test run operation can
be stopped manually by pressing the button once. If there are
misconnections or malfunctions, an error code will be displayed
on the remote controller. Otherwise, the remote controller will
return to normal operation.
6 To resolve the error codes, see "9.5.2. Error codes" on page 26.
7 Check the leaving water and entering water temperature through
the remote controller read-out mode and compare them with the
values noted with step 1. After 20 minutes of operation an
increase/decrease of the values should confirm the space
heating/cooling operation.
9.4. Handover to the user
Once the test run is finished and the unit operates properly, fill-in the
sheet "Handover of the installation to the user" which is in "Annex" on
page 26.
9.5. Service and maintenance
In order to ensure optimal operation of the unit, a number of checks
and inspections on the unit and the field wiring have to be carried out
at regular intervals.
This maintenance should be carried out by your local installer.
To execute maintenance first remove the panels as shown in
"7.1. Opening the unit" on page 4.
9.5.1. Maintenance activities
Checks
The described checks must be executed at least once a year by
qualified personnel.
1 Pressure relief valve hose (if present)
Check that the pressure relief valve hose is positioned
appropriately to drain the water.
2 Water pressure relief valve
Check for correct operation of the pressure relief valve by
turning the red knob on the valve counter-clockwise:
If you do not hear a clacking sound, contact your local dealer.
In case the water keeps running out of the unit, close both
the water inlet and outlet shut-off valves first and then contact
your local dealer.
3 Switch box
Carry out a thorough visual inspection of the switch box and look
for obvious defects such as loose connections or defective
wiring.
4 Water pressure
Check if the water pressure is above 1 bar.
If necessary add water.
5 Water filter
Clean the water filter.
INFORMATION
To display the last resolved error code, push the button
1 time. Push the button again 4 times to return to
normal mode.
INFORMATION
It is not possible to perform a test run if a forced operation
from the unit is in progress. Should forced operation be
started during a test run, the test run will be aborted. The
external control icon will appear.
DANGER: ELECTRICAL SHOCK
See "4. Precautions for installation" on page 2.
WARNING: ELECTRIC SHOCK
Before carrying out any maintenance or repair activity,
always switch off the circuit breaker on the supply
panel, remove the fuses or open the protection
devices of the unit.
Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.
Please note that some sections of the electric
component box are hot.
Make sure you do not touch a conductive section.
Do not rinse the unit. This may cause electric shocks
or fire.
Play it safe!
Touch a metal part by hand (such as the stop valve) in
order to eliminate static electricity and to protect the PCB
before performing service.
