Field settings

Make the following field settings so that they correspond with the
actual installation setup and with the needs of the user:
▪ Ceiling height
▪ Air flow direction
▪ Air volume when thermostat control is OFF
▪ Time to clean air filter
Setting: Ceiling height
This setting must correspond with the actual distance to the floor,
capacity class and air flow directions.
▪ For 3-way and 4-way air flows (which require an optional blocking
pad kit), see the installation manual of the optional blocking pad
kit.
▪ For all-round air flow, use the table below.
If the
distance to
M C1
the floor is
(m)
≤2.7 13 (23) 0
2.7<x≤3.0
3.0<x≤3.5
Setting: Air flow direction
This setting must correspond with the actual used air flow directions.
See the installation manual of the optional blocking pad kit and the
manual of the user interface.
Default: 01 (= all-round air flow)
Example:
a b
a All-round air flow
b 3-way air flow (1 air outlet closed) (optional blocking pad kit
required)
c 2-way air flow (2 air outlets closed) (optional blocking pad
kit required)
Setting: Air volume when thermostat control is OFF
This setting must correspond with the needs of the user. It
determines the fan speed of the indoor unit during thermostat OFF
condition.
1 If you have set the fan to operate, set the air volume speed:
(1)
Field settings are defined as follows:
▪ M: Mode number – First number: for group of units – Number between brackets: for individual unit
▪ C1: First code number
▪ C2: Second code number
▪ : Default
(2)
Fan speed:
▪ LL: Low fan speed
▪ Setup volume: The fan speed corresponds to the speed the user has set (low, medium, high) using the fan speed button
on the user interface.
▪ Monitoring 1, 2: The fan is OFF, but runs for a short time every 6 minutes to detect the room temperature by Low fan
speed (1) or by Setup volume (2).

Setting: Time to clean air filter
This setting must correspond with the air contamination in the room.
It determines the interval at which the TIME TO CLEAN AIR FILTER
notification is displayed on the user interface. When using a wireless
user interface, you must also set the address (see the installation
manual of the user interface).
If you want an interval of...

Commissioning

NOTICE
NEVER operate the unit without thermistors and/or
pressure sensors/switches. Burning of the compressor
might result.
7.1

Overview: Commissioning

This chapter describes what you have to do and know to
commission the system after it is installed.
Typical workflow
Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing a test run for the system.
7.2

Precautions when commissioning

INFORMATION
During the first running period of the unit, the required
power may be higher than stated on the nameplate of the
unit. This phenomenon is caused by the compressor, that
needs a continuous run time of 50 hours before reaching
smooth operation and stable power consumption.
