To Perform An Air Purge On The Brine Circuit; To Perform An Operation Test Run; To Perform An Actuator Test Run; To Perform An Underfloor Heating Screed Dryout - Daikin Altherma 3 GEO Installation Manual

7 Commissioning
7.2.2 To perform an air purge on the brine
circuit
There are two ways to perform an air purge on the brine circuit:
▪ with a brine filling station (field supply)
▪ with a brine filling station (field supply) in combination with the
unit's own brine pump
In both cases, follow the instructions included with the brine filling
station. The second method should only be used when the air purge
on the brine circuit was NOT successful using only a brine filling
station. See "To perform an air purge with a brine filling station" in
the installer reference guide for more information.
In case a brine buffer vessel is present in the brine circuit, or if the
brine circuit consists of a horizontal loop instead of a vertical
borehole, further air purging may be required. You can make use of
the 10 day brine pump operation. See
day brine pump operation" on page 33
7.2.3

To perform an operation test run

1 Set the user permission level to Installer. See
change the user permission level" on
2 Go to [A.1]: Commissioning > Operation test
run.
3 Select a test from the list. Example: Heating.
4 Select OK to confirm.
Result: The test run starts. It stops automatically
when done (±30 min).
To stop the test run manually:
1 Go to Stop test run.
2 Select OK to confirm.
If the installation of the unit has been done correctly, the unit will
start up during test operation in the selected operation mode. During
test mode, the correct operation of the unit can be checked by
monitoring its leaving water temperature (heating/cooling mode) and
tank temperature (domestic hot water mode).
To monitor the temperature:
1 Go to Sensors.
2 Select the temperature information.
7.2.4

To perform an actuator test run

Purpose of the actuator test run is to confirm the operation of the
different actuators (e.g., when you select Pump, a test run of the
pump will start).
1 Set the user permission level to Installer. See
change the user permission level" on
2 Go to [A.2]: Commissioning > Actuator test run.
3 Select a test from the list. Example: Pump.
4 Select OK to confirm.
Result: The actuator test run starts. It stops
automatically when done (±30 min for Pump,
±120 min for Brine pump, ±10 min for other test
runs).
To stop the test run manually:
1 Go to Stop test run.
2 Select OK to confirm.

▪ Backup heater 2 test (6 kW capacity, only available when no
current sensors are used)
▪ Pump test
INFORMATION
Make sure that all air is purged before executing the test
run. Also avoid disturbances in the water circuit during the
test run.
▪ Shut off valve test
▪ Diverter valve test
▪ Bivalent signal test
▪ Alarm output test
▪ C/H signal test
▪ DHW pump test
▪ Backup heater phase 1 test (3 kW capacity, only available
when current sensors are used)
▪ Backup heater phase 2 test (3 kW capacity, only available
when current sensors are used)
▪ Backup heater phase 3 test (3 kW capacity, only available
when current sensors are used)
▪ Brine pump test
7.2.5 To perform an underfloor heating screed
dryout
Conditions:
▪ Make sure all operation is disabled. Go to [C] Operation and turn
off [C.1] Room, [C.2] Space heating/cooling and [C.3] Tank
operation.
▪ Make sure [2.7] and [3.7] Emitter type is set to Underfloor
heating.
1 Set the user permission level to Installer. See
change the user permission level" on
2 Go to [A.4]: Commissioning > UFH screed dryout.
3 Set a dryout program: go to Program and use the
UFH screed dryout programming screen.
4 Select OK to confirm.
Result: The underfloor heating screed dryout starts.
It stops automatically when done.
To stop the test run manually:
1 Go to Stop UFH screed dryout.
2 Select OK to confirm.
NOTICE
To perform an underfloor heating screed dryout, room frost
protection needs to be disabled ([2‑06]=0). By default, it is
enabled ([2‑06]=1). However, due to the "installer-on-site"
mode (see "Commissioning"), room frost protection will be
automatically disabled for 36 hours after the first power-on.
If the screed dryout still needs to be performed after the
first 36 hours of power-on, manually disable room frost
protection by setting [2‑06] to "0", and KEEP it disabled
until the screed dryout has finished. Ignoring this notice will
result in cracking of the screed.
