Determine the attachment position of the redundancy controller housing following these guidelines:
•
Position ideally half way between the 2 indoor units or in the center of the 3 indoor units or of the
group of units.
•
Install so that the room temperature sensor (factory mounted on the left side of the box) is located
at a representative room position. The sensor comes with a 1 m extension cable already fitted
within the box. You may place the sensor also outside the box. In this case please use field
supplied fixing material (such as small pipe clips). Please do not extend this wire by standard wires,
as it is a thermocoupler element you need special extension cable for thermocouple elements type
K) . The temperature sensor is flexible and may be ajusted according to local needs, however do
not use force in order to not brake it.
•
Maximum wire length between the control box and each of the indoor units must not exceed 10 m
•
Within 1,5 m of the control box a 100 - 240V AC socket must be provided for the power supply
•
Take especially care that the controller is not mounted near to an external heat source
•
Take care that there is enough space to plug and unplug the power supply to the box (on the left
side) and to be able switching the controller on/off. Free access must be provided to the front plate
for the setup and wiring etc.
