Installation
4.3 Installation of thermistors
ATTENTION
Damage to the thermistor wires
Exposing the wires of thermistors to the outside and/or to direct sunlight might damage the wires
and should therefore be avoided.
►
Attach the AHU Kit either directly to the Air Handling Unit or to a wall nearby and make
sure that it is not exposed to direct sunlight.
►
Use protecting wire ducts to avoid exposing the wires of thermistors and the electronic
expansion valve to the outside.
When installing the thermistors, the following limitations and restrictions need to be observed:
●
Wires must not be put out of equipments.
●
Wires must not be cut and connector of wires must not be detached.
● Thermistors must be Identified by the tag which is wound to each thermistor.
●
The head of the thermistor must be attached exactly onto the pipe, because the head
is the most sensitive point of the thermistor.
Maximum contact
Most sensitive point of the thermistor
●
The thermistor wire must point downwards from the thermistor to avoid water reaching
the thermistor.
●
The thermistor wire must be inserted drooped in the AHU body with the drooping wire
being close to the AHU Kit.
