5.7 Setting up an external temperature
sensor
You can connect one external temperature sensor. It can measure
the outdoor ambient temperature. ROTEX recommends to use an
external temperature sensor in the following cases:
Outdoor ambient temperature
In the outdoor unit, the outdoor ambient temperature is measured.
Therefore, the outdoor unit must be installed on a location:
At the north side of the house or at the side of the house where
the most heat emitters are located
That is NOT exposed to direct sunlight
If this is NOT possible, ROTEX recommends to connect a remote
outdoor sensor (option EKRSCA1).
Setup: For installation instructions, see the installation manual of
the remote outdoor sensor.
Configuration: Select outdoor sensor [A.2.2.B].
During suspend (see "8 Configuration" on page 47), the outdoor
unit is turned down to reduce the standby energy losses. As a
result, the outdoor ambient temperature is NOT read out.
If the desired leaving water temperature is weather dependent, the
full time outdoor temperature measurement is important. This is
another reason to install the optional outdoor ambient temperature
sensor.
INFORMATION
The external outdoor ambient sensor data (either averaged
or instantaneous) is used in the weather-dependent control
curves and in the automatic heating/cooling changeover
logic. To protect the outdoor unit, the internal sensor of the
outdoor unit is always used.
6 Preparation
6.1 Overview: Preparation
This chapter describes what you have to do and know before going
on-site.
It contains information about:
Preparing the installation site
Preparing the refrigerant piping
Preparing the water piping
Preparing the electrical wiring
6.2 Preparing installation site
Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit must be covered.
Choose the installation location with sufficient place for carrying the
unit in and out of the site.
6.2.1 Installation site requirements of the
outdoor unit
INFORMATION
Also read the following requirements:
General installation site requirements. See the
"General safety precautions" chapter.
Service space requirements. See the "Technical data"
chapter.
Refrigerant piping requirements (length, height
difference). See further in this "Preparation" chapter.
Select a place where rain can be avoided as much as possible.
Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.
Do NOT install the unit in the following places:
Sound sensitive areas (e.g. near a bedroom and the like), so that
the operation noise will cause no trouble.
In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
It is NOT recommended to install the unit in the following places
because it may shorten the life of the unit:
Where the voltage fluctuates a lot
In vehicles or vessels
Where acidic or alkaline vapour is present
Seaside installation. Make sure the outdoor unit is NOT directly
exposed to sea winds. This is to prevent corrosion caused by high
levels of salt in the air, which might shorten the life of the unit.
Install the outdoor unit away from direct sea winds.
Example: Behind the building.
